What's wrong with this picture?




Can you spot two things?

Those with a keen eye will notice the larger screen space of my GEM desktop. What about the three resolutions that appear selectable? If you saw these things, then you're an Atari ST rock star. I salute you!

I've been experimenting with a few GEM programs that allow larger resolutions and other cool stuff. Some use interlacing to double the vertical resolution, but that can look odd and hurt my eyes! (use 60Hz!!). Others can create a virtual screen by using the Atari STe's hardware scrolling. Why would you wanna scroll?

Interestingly, some programs feature overscan. This is a technique used to make use of the empty borders, and it sparked my curiosity. Using this extra screen space is great, and without any slowdown. Most GEM programs should work perfectly fine, and I'm left wondering why Atari couldn't have made this standard?

I've made a bundled download of these programs - please let me know if there are others I've missed.
