Can anyone enlighten me why some Amiga games are displayed in full screen, some games take up about 3/4 of the screen and some games some other weird portion of the screen? Is it to accelerate games when they use less of the screen? I've also noticed that AGA games are more likely to run full screen than not. Why? Is there a way to force games to use full screen?
Assuming you have a PAL amiga, the games that appear to be vertically short are those that were designed for NTSC, which has a somewhat lower vertical resolution than PAL.
