SDI: Now The Odds Are Even

The Star Wars program is happening!

It's incredible how quickly time passes, as I've not played this since I got my first Atari ST. The Sega shooter was converted by Alaric Binnie for Activision and released in 1988. I remember being impressed and unimpressed in equal measure - probably because I liked what I saw but was absolutely terrible at playing it!

As most of us, older gamers might remember, SDI stands for Strategic Defence Initiative and is based on the original Star Wars concept by President Regan devised during the Cold War. This technology was supposed to defend Earth from the inevitable Soviet attack. Yeah, I know, it never happened... shocker, right?

The game is an action shooter set within the darkness of Earth's space. As it turns out, the defence initiative is just a lone satellite armed with a laser gun! Use that to protect mankind from a legion of Soviet nuclear missiles, fighters, and more. Why only one satellite, I don't know, but that's the game, so let's crack on.

Okay, let's take the first break from reading with two sexy screenshots...

The Soviets are sending everything they have. Well, in stages, thankfully.

At first, it was distracting to see the moon moving by. I should have been concentrating!

The fate of mankind...

Our quest begins with the Space Shuttle dropping us off before a barrage of Soviet missiles appears. The game is split into two separate modes, depending on your performance: offensive and defensive. The first is not unlike other horizontally scrolling shooters, attacking everything that swarms onto the screen. The second is like a 3D Missile Command and a final chance to save everyone from the previously missed missiles.

You'll soon discover that SDI isn't a complex game at all. It's a frenzied shooter battling squadrons of enemy artillery. So shoot everything as quickly as you can physically move the mouse. Each stage gets more aggressive, right up until the point my hand-to-eye reactions simply cannot cope anymore (see the video!).

No need to fret, you're not alone, as allies will periodically send power-ups. Sadly, during the heat of battle, these look similar to everything else! Especially when you're in a mindset of blasting everything as quickly as possible. This means they’re destroyed far too quickly to collect their cargo as you watch it drift away. Sigh...

The damage meter at the bottom of the screen shows your performance’s current state. Survive, and the Space Shuttle reappears to whisk you off to safety, where that performance is rated on a scale. Anything less than perfect and you're sent through to a defensive stage to help defend from the attack. A perfect score gets you lots of extra points with a blue dancing duck. (And that makes it all worthwhile!!)

Are you bored with reading this? Chill. Take five. Look at these screenshots...

The blood-red moon looks awesome. Don't admire, concentrate on the killing!

I let some missiles get through, so now I'm defending the base Missile Command style!

Input

SDI might seem tricky because you need to do two things simultaneously: keep the satellite safe and select its firing direction. Arcade games can sometimes lose functionality when converted to a home computer. Not here; all controls are fully configurable using a combination of mouse, joystick and keyboard.

It is possible to use only the mouse, but I wouldn't advise it. I use the keyboard to direct the satellite and my mouse to aim/shoot. A joystick would also be a good idea, but only if it has good suckers to stick onto your desk. The keyboard/mouse method is kinda like the WASD/mouse combo as used in FPS games.

This plays great, but that doesn't mean we don't want screenshots. So, here you are...

It's not long before things get crazy with lots to shoot at. Trigger-happy heaven!

Ignore the asteroid shower because it's time to shoot more of that Ruskie hardware.

Output

Space is mostly empty, but the good thing about this Cold War is celestial objects as backgrounds rather than being empty. All graphics are by Bryn Redman, who treats us to images of the Earth, its Moon and an asteroid field - I believe later levels feature the Death Star? My gaming skills won't allow me to witness it!

The darkness of space dictates a sombre palette, which suits the Cold War scene, but there are brighter moments to behold. I love the red moon that boldly stands out; it looks amazing. Sadly, there is some slowdown during the later levels that are bombarded by tons of enemies. Meh, I can live with that as it's not too bad.

Paul Summers is responsible for the audio, and he did a stellar job (see what I did there?). The title features a grungy sample, but nothing compares to the in-game chiptunes. These are subtle and suit the ambience whilst also complementing the zappy effects. To say I adore these tunes would be an understatement!

Breathe and relax as it's the final screenshot break before the gripping conclusion...

Come on, the defensive stages really are Missile Command. Rip-off but brilliantly done!!

Do well and make the high-score table. Hang on, this feels like a game in itself? ;-)

The CryptO'pinion?

SDI could easily have been a bust due to the control system and visual demands. Alaric Binnie has done a fantastic job, not only aesthetically speaking but also in migrating the arcade's control system to the ST by using its keyboard/joystick and mouse. This combination works a treat, a commendable effort.

I usually find something to moan about, so here we go: I failed to see the logic in having a dark blue cursor against the dark backgrounds. Also, the power-ups are so difficult to catch. No, impossible (for me) to catch!! Finally, why aren't we treated to a nuclear explosion at Game Over? Oh, how I wanted to see that...

Some might say it's an alternative to Missile Command, and I get that; the similarities are there. SDI is an exciting shooter and one that is utterly addictive, albeit I'm shockingly bad at it. Make sure you choose the control method that suits you to prevent Western civilisation from catastrophic demise!

Let me know in the comments what you think about SDI (download for hard drive or floppy disk)

Sophélie

Bums and Boobs!

Sophelie was once a goddess of heaven, but has since been vanquished and left to roam the lands searching for her body. What? Why? Well, some kind soul has turned her into an albatross, so she now spends time flying through worlds looking to find her original appearance. As storylines go, this is silly, to say the least!

This is a horizontally scrolling shooter, not too dissimilar to Menace. This time, we're not killing monsters or aliens, but some of the weirdest things you might never have expected: planets, snowmen, wolf heads, eyeballs, and even trees. The landscapes are lush with colour, and even angels will regularly appear to help.

Sounds great, right? Well, let's take a look at some screenshots from the first level...

Yep, giant eyeballs are coming for you and are actually tough to kill, too!

Now, this is getting silly! What have the trees ever done to you?

Let's kill the planet? No, literally by shooting down the rotating planet Earth!!

Spit, don't shoot!

We begin with the hand of God safely delivering us, ready for battle. The levels are split into segments, with each having its own brand of baddies all too eager to see you dead. The controls are fast and responsive, and a joy to control without any lag. The gameplay is fast and exciting as each enemy will swarm onto the screen using its unique attack pattern. Some shoot at you, like the Earth enemies firing mini-planets. Cool.

Some of the nasties are easy to kill, whereas others are impossible, thanks to the slow rate at which we can shoot. This makes killing certain enemies tough because they move too quickly in comparison to our fire rate. Dying can be a bit troublesome, especially when you materialise close to an enemy and therefore instantly die once again. A simple invulnerability effect could have been utilised for a second or two!!

Angels visit after each segment with power-ups, which are essential from the start. Miss them, and the following swarm of enemies is quite impossible to defeat. Also, dying baddies might sometimes throw out an extra power-up, but these fall off the screen before you've had a chance to even think about collecting them. Finally, there is a time limit ticking down to kill each wave of baddies. Very peculiar, to say the least.

Let's end the whining and take a look at some screenshots from the second world...

Some of the sprites are freaky... freaky-cool!

I can't make out whether these are balloons or floating severed heads!

Damn snowmen, they all deserve to die!! O_o

Aesthetics?

Visually, I like the colourful palettes, funky sprites racing across the screen, and smooth parallax scrolling running at a brisk pace. I love the level of detail that's gone into the sprite's artwork. Sophelie's animation is superb, and never have I played a game with such a wacky variety of different enemies. They're quite insane!!

Sadly, the audio is disappointing with a fuzzy tune and near-silent gameplay. Well, apart from the death-killing sound effect and a strange background whistle. It's shocking because the YM is far more capable.

Well, that was a mixed bag, alright, so let's take a peep at the third world...

These are insanely difficult to kill, if not impossible, without losing all your lives!

He's big. He's bad. He's about to be brown bread!!

Hey, a power-up appears from a dying beast, yet you have no chance of collecting it!

The CryptO'pinion?

This isn’t a terrible shoot 'em up. The colourful levels and impressive baddies zipping across the screen create a constant action-packed experience. Plus, the occasional appearance of angels with gifts to boost your chances of victory adds a nice touch. Sadly, it’s also one of the most boring shooters I’ve played. While the graphics might change, the gameplay constantly remains the same. And then there's the audio... Ugh, terrible!

Technically superb, but it’s an understatement to say there are better Atari ST shooters. Sophelie looks nice, but sounds awful and is very repetitive. While there are boobies, I’m not convinced it’s worth playing.

If you're curious, then grab the floppy disk at Atari Legend. Enjoy...

Oh no, another grisly death beautifully laid out. Interesting artwork!

Recovery

The Atari ST cannot scroll

Recovery is a shooter by New Deal Productions that takes us on a *Fantastic Voyage* through the lower parts of some poor soul in need of medical assistance. I presume we're trying to help him recover from something nasty as we begin at the bottom, working our way up through the liver (I think), and then onto the heart before finally smashing through the old grey matter. Yeah, we get to rock through the human body!

This game is very similar to Menace or R-Type, but at a faster pace. The whizzing body parts make dodging almost impossible. Our ship is agile and armed with a laser, so don't think - shoot first and never ask dumb questions. I love finding something 'new' to play, and this is an exciting shooter.

Let's take a break and see some screenshots...

I got AGT vibes from this screenshot, which pleased and depressed me equally.

It's a shooter, so shoot!

Each body part represents a distinct stage and is incredibly long, almost making you think it will never end. Trust me, these levels are lonnnnnng. Despite this, they all feel similar, presenting a vast array of "aliens" to avoid or eliminate. These employ various attack patterns, but touching them depletes energy levels. Consequently, poorly skilled pilots ultimately lose yet another life. Interestingly, there’s no end-of-level boss. A monstrous tumour would have been a fitting final boss - now that’s a sentence I never thought I’d say!

The joystick controls are excellent - swift and responsive without any lag. Our main weapon is an effective laser beam - pressing and holding fire shoots this laser and kills anything in front of you. It's wicked!! Sadly, there are no other types of upgrades or special weapons, so all we have is one laser and nothing more.

Thankfully, our sleeping patient has popped many pills, which you'll see floating through his body just waiting to be collected. These can boost your weapon's rate of fire, energy and shields, which are all displayed in the status bar. I never figured out what "LIGH" is for - I tried hitting every key, but nothing, nada, zip.

Let's take a break from the boring reading and view another lovely screenshot...

A menacing screenshot with the colour scheme. This game is fast, so shoot and move quick!

Aesthetics?

Visually, this is a mixed-body bag that isn't as healthy as you would hope. Don't get me wrong, a scrolling shooter needs to scroll. And this game scrolls smoothly with parallax layers. Sadly, the backgrounds are sometimes bare-bones. Although there are tons of sprites zooming around at impressive rates!

Hitting F4 flips between 50/60Hz to speed things up even more - if you can handle it?

Sonically, this is outstanding and foot-tappingly awesome - makes you realise just how cool your Atari ST is. However, any insane people might wish to turn it off for the sound effects. No problem, just hit F2/F3, but why would you ever wanna do that? Wait, I think that I know the answer, it's because you're stupid.

Okay, you've guessed it - stop reading and enjoy another gorgeous screenshot...

Come on, you cannot deny the style of this game? It looks the business with a style I love.

The CryptO'pinion?

Recovery is technically impressive and a damn good shooter. It slaps the faces of those lazy programmers who said the ST cannot scroll. Sadly, the gameplay could be better, as each stage feels excessively long, and that static style lacks progression and becomes monotonous after a while. Furthermore, the inability to upgrade our weapons is a significant disappointment, but not as much as the absence of bosses to fight.

I've enjoyed blasting through some fella's intimate body parts all in the name of science fiction. Recovery is definitely worth booting up for a quick game or two - especially to see who can survive the longest!!

Check out my screenshots before deciding whether to download for hard disk or floppy...

Zynaps

Just a freebie?

Zynaps is a Nemesis-Esque shoot 'em up that spookily reminds me of another Hewson title, Slayer. We pilot the Scorpion Mk1 Fighter through the heavens in search of a secret alien base. Greeting you are hordes of alien scumbags: in ships, a variety of ground-based defences, and even motherships. Very original, right?

Update: you know, to this day I have still never played Slayer. How odd is that!

Hewson released Zynaps in 1988, and it was developed by Howard Ball of Microwish Software. I've always felt this was a game coded by someone who knew the Atari ST hardware very well, but Howard only ever made this shooter and nothing more. Lost potential there, I fear. At least his only game is quality!

Hey, why aren't you watching the video above? Ah well, perhaps a couple of screenshots then...

The first level is cool, but it isn't long before a guardian appears!

That thing bounces around the screen like an old-school demo!

Shoot! Kill! Shoot some more!!

Our Scorpion spaceship is snazzy with different levels of propulsion and weapon upgrades. However, we do start off limited with sluggish movements and firing, so shoot that first wave of bad guys to collect their loot for speed-up. Then look to improve lasers or even bombs and missiles. It's simple - pimp your ship!

Activating these power-ups is a little strange. When a group of baddies snuffs it, they leave behind a pod. Collecting that changes the power-up being displayed in the status bar. So when something appears that you like the look of, hold down the fire button during the next pick-up to be granted permission to use it. To be fair, this is rather naff - especially during the heat of battle. Surely this could have been designed better.

The enemies attack in predictable formations, which reminds me of Wizball, oddly enough. At first, firing accuracy is difficult, so hitting the baddies feels a lot harder than it should be. This learning curve is massive - it took many attempts before I started to destroy an entire wave (and then begin collecting the pods!).

That's annoying, isn't it? Well, let's cheer ourselves up and see some more screenshots...

Woo! What's happened to the landscape backgrounds on the next level?

Getting past the asteroids is tough, but now it's a boss fight, and he's a bit weird...

Practice makes perfect!

Most levels take you through beautiful environments, whereas others are a bleak asteroid field. No matter where you are, watch out: the slightest collision can cost a life, which can easily be done. This is made worse by ultra-cramped areas thanks to the bulk of that scenery (and the status bar). Fly like Buck Rogers... or die.

Eventually, you reach an end-of-level boss, and most are tough - so it's doubtful you will be victorious right away! The first boss hops around the screen like a sprite from an old skool-styled demo. Rarely did I see the end of the second level (without using a trainer), but YMMV. Just don't give up, you wimp and keep playing!!

Wimps only ever see the first level, so practice, and you might see more! Screenshot time...

Things get freaking on level 3, but it's a good kind of freaky :-)

Well, except for the boss(es). Very lame!

Graphics

Zynaps is a gorgeous shoot 'em up. Sure, games like Xenon 2, Magic Boy, Gods, Deathbringer, and others blow it out of the water, but this old shooter (from 1988) holds its own thanks to the efforts of Pete Lyon!! The title screen is wonderful - pure art - and many levels feature a Menacing array of beautiful environments.

That's not all, the sprites move fast and very smoothly, following those incredibly difficult flight patterns. But what about the scrolling? Programmers without talent tell us the ST cannot scroll. Well, don't worry because it's nigh-on perfect and very smooth, so feels just dandy. Yep, this is another quality Hewson product.

For me, Hewson were consistent, without resorting to lame ports...

Things get a little Menacing for the fourth level.

It looks stunning - if deadly. I never beat it...

Sounds

The theme tune is outstanding thanks to the talent of a favourite musician, Dave Rogers: a man responsible for many of my ZX Spectrum memories, not to mention ST beauties like Ranarama and Cybernoid.

The sound effects might pale in comparison to the music, but they're excellent and offer an arcade-like style which I really admire. I love that sharp "zing-zing" when you shoot, the crunchy death effect, and how you are mocked when it's game over. Like the visuals, a lot of love went into the audio, which is brilliant.

Yep, the audio proves what the Atari ST can sound like. Wanna hear it...

The Crypto'pinion

This is one of those games that has it all, but many give up after a few goes because of its learning curve. The action is relentless, so you're always on the edge of your seat. The method of using power-ups might be flawed, but these are essential to enhance the Scorpion with better firepower and manoeuvrability.

Zynaps is yet another corker from Hewson's incredible library. Sure, I've moaned about a few things, but nothing is perfect, and it has a massive "one-more-go" factor. What an extraordinary shoot 'em up, and it's a great feeling to end my Super Pack series on a high. You need to play this game.

Grab the floppies if you have the skills

I recommend these excellent HD versions by Klaz and PP.

Return To Genesis

Dream Team?

Firebird released Return To Genesis the same year I got my Atari ST, and it was developed by the "ST Dream Team": Steve Bak, Pete Lyons, and David Whittaker. Three masters in their fields, who aimed for quality and always pushed our computer without ever resorting to excuses or using a lame Amiga port. #respect

RTG is a spin on Defender, where Mechanauts have forced scientists into slavery. We've gotta rescue each of these guys, which means jumping into a spaceship to skim the surface of 50 psychedelic worlds.

Wanna see the first bunch of screenshots? Then wait no longer because here they are...

Weeeee..... swooooosh..... ZOOOOM......... dead!

Can you see the Mechanauts? Not easy, is it?

I'm getting too old and slow

If you've ever played Defender, then you should be right at home with RTG. It only has a tiny learning curve. Fire and kill everything? But it's worth slowing down to pick up the scientists rather than killing them: once onboard, hit the HELP key to see what power-ups they might provide. These guys are useful and could improve weaponry, shields, invisibility, etc. However, Festus might be less than fun as the master of self-destruction?

A scanner shows the location of each scientist, but this falls short of detailing the level layout. I don't know why, but this doesn't work well for me. Sigh... how many more times must I be rebounded back and forth like a yo-yo? Yes, you're on the edge of your seat for this incredibly FAST shooter. Blink, and you're dead!!

Screenshot time, and here are twelve scary-looking people from the future...

This is an incredible idea that uses who you rescue in a positive way for the next level. It's superb!

Aesthetics

Pete Lyon designed everything you see, but I'd be lying if I said this was his best work (I personally think Zynaps won that accolade). It's pretty gorky, so I often found it difficult to distinguish the aliens against those funky backgrounds. The scrolling is smooth to prove, once again, that the Atari ST needed no custom chips when in the hands of talented people who care about the product they're working on.

Audio is such a treat. Dave Whittaker sure knew how to get the best heard from our computer - proving that "chipmusic" will last forever. Yes, it sounds <cough> familiar, but it suits the gameplay. Heck, our ST talks to us, which is a zillion times better than Gold Runner. Dave certainly gets the YM processor rocking.

It looks, moves, and sounds superb! Definitely a dream team production, so let's see screenshots...

A weapons upgrade. I knew it was better to rescue these guys rather than blasting 'em!

Shall we rescue him or not? Erm, I shall.... try....!!

The CryptO'pinion?

Return to Genesis is one of those games that seems to have it all - brilliant visuals, smooth scrolling, immersive sound effects, and classic chip tunes. However, I’m left feeling unsure if it’s the game itself or just me. I love a good Defender-inspired shooter, but this one’s way too fast. After a few pointless games, I’m exhausted from hitting objects and dying repeatedly. Thankfully, the scientists have some great power-ups. These are a wonderful idea that somewhat alleviates the frustrating gameplay, albeit just a tiny bit.

This sure is an iconic shoot ‘em up for Atari ST gamers, truly representing the ST’s capabilities. Unfortunately, it’s far too fast for me, and I’d much rather play Zynaps or Menace. I wanted to love this game, but it just wasn’t for me. It’s brilliant, but sadly, not for this gamer. I guess I’m just too old and slow?

Grab it for floppy or hard drive.

Supa Zazai Da!

Super... what?

Supa Zazai Da is another Gamopat conversion by Templeton, the same genius who graced us with the stupendous Crash Time Plumber. I couldn't wait to get my grubby mitts on this after reading the superb review by ST Graveyard on Atari Legend. Sadly, I admit to being disappointed with it. I failed to play more than a handful of frustrating games before rebooting my Atari STe with a massive portion of dismay.

I'll never knock anything powered by Maria Whittaker (yeah!), but this is rock solid and difficult!! Having only one life didn't help, especially when the enemy could fill the entire screen with bullets! Yep, this is a wolf in sheep's clothing and seemed like a bad joke. Dang, I was incredibly bad at it and genuinely gutted.

I know, I know, those first impressions of a weak gamer. Sigh, but read on...

Trust me, this game will destroy you and any expectations for success!

Don't judge a book by its cover

I returned and anxiously grabbed my creaky old joystick, determined, but expecting the battle of my life. After many embarrassing failures, I eventually beat the first horde of nasties and even gained extra points thanks to the green particles. How I managed to dodge the enemy's bullets, well, it felt like a personal achievement!! The clue is how you navigate through the cloud of bullets; it's easier than you think (watch the video).

Nevertheless, the scary boss gave me a good drubbing, and I was again greeted with the Game Over screen. I defeated him on my next nerve-racking attempt, so I was close to tears and ecstatic!! Once the second level begins, you realise there's a familiar and repetitive pattern, so I hammered it home and battled onto the third and fourth levels, with relative ease. The lesson is to stick with it, as it can be conquered!!

Talk about a massive learning curve. Or at least for me? Wow, this game is so rewarding...

However, nobody said those bosses would be easy. Especially when they can fire so much!!

Pixels and Sonics

The visuals scroll at an ultra-smooth 50fps. It's the outrageously cute sprites, from a wide variety of games, that everyone will adore. Your computer will require a Blitter coprocessor, which is not a problem for the Atari STe and Falcon, but the original ST models are outta luck (unless you have a later revision or a Mega ST).

Musically, Supa Zazai is great but different depending on your hardware: an unnerving chip rattles ST players, whereas the STe gets exhilarating streamed audio (both brilliant). As instructed, pump up the volume!

It looks and sounds fantastic, is what I'm saying about this Blitter-boosted game...

50fps action through, and just look at that huge sprite. Impressive, to say the least!!

The CryptO'pinion?

What a journey!! It's nothing like I initially imagined, yet it lived up to my expectations at the same time, which is weird. Arcade fans are going to drool over their keyboards because this shooter is fast, fun, thrilling, and addictive. Quite simply, Supa Zazai Da is an exhilarating game with gorgeous aesthetics.

I hope Templeton has many more Atari STe games in the pipeline, I really do.

Menace [upgraded]

When something isn't quite right...

Menace is one of the few Psygnosis games that I respect. It's a good shooter. Okay, it should have been better with a little effort, but that's an Amiga company for you. Anyhow, it's still a decent game, and I enjoy it. But what's with the YELLOW ship compared to that other version? For years, I've hated its bland colour and wondered what they were thinking. And if it was possible to change it for something better?

So I contacted Atari ST wizard Peter Putnik about my dilemma. He's always up for a challenge and open to ideas. It wasn't long until he came back with a solution that worked well. As you can see in both the video and screenshots, our spaceship now has a new paint job!! The caveat is a change to the (badly placed) status pane due to the 16-colour palette. Of course, the game remains the same, but we now pilot a white ship!

You know, folks, this is what makes the Atari ST scene a marvellous place. Think about it, I wasn't happy with a commercial game from 30+ years ago. I asked a guy living in another country for his thoughts. What does he do? He fixes it without hesitation. Incredible. What an amazing community we have.

My sincere thanks to Peter for being gracious with my request. This version of Menace is the only one I will play on the Atari ST. Here's the download to the newly designed AtariCrypt White Star (geddit?).

Please watch the video trailer above and gander at these lovely screenshots...

I made this silly image. Can you tell? lol

Here it is, our brand new white ship!

Just look at it. Much better now, albeit at the expense of the status bar.

Skimming along through space in my spanky new ship!!

It might not be the best shooter, but the graphics are cool.

It has its haters, but this is better than most of the drivel Psygnosis produced for us.

P-47

Skim the landscape & shoot everything

P-47 was released in 1988 by Firebird and is based on the Jaleco arcade game. There are several levels through a variety of landscapes, so put on your Biggles outfit because you're about to reach for the skies.

Any shoot 'em up needs decent scrolling, awesome controls, and enemies to kill. P-47 has this by the bucketload. It's immediately obvious that the teamwork that went into development has certainly paid off. Choose either a 50/60Hz display with smooth parallax scrolling, great graphics throughout, and fast sprites that honour the original. Funky chipmusic plays alongside the pizazz sound effects, both of which are great.

The action is hectic as the planes whizz into view and tanks blast artillery - they're just asking for a MOAB!! Other levels have us flying through sunset clouds, pyramids, and over the seas (I love the missiles, which emerge from underwater). Oddly, the bosses are easy to defeat by positioning in a safe place and repeatedly dropping a payload of bombs. Each level varies, but the concept remains: fly, avoid, panic, and kill everything.

Where P-47 fails is the frustratingly great difficulty - the screen will always be cluttered with many baddies, and a collision is inevitable. Stick with it; collect the power-ups, learn the enemy's attack pattern, and keep on firing. Sure, this is imperfect, but it's also one I really enjoy and a darn challenging shoot 'em up.

• Atari Legend has the floppies, and I recommend New Order #20 Menu CD.
• Hard drive installable versions are available by both 8BitChip and D-Bug.
• Enter "ZEBEDEE" into the high score:
• Press F1 for a level skip
• press F2 for infinite lives. Have fun!!
