I tracked down a boxed copy of The Sentry (1987) -- also known as The Sentinel, apparently. It's a color game, but I don't have a color monitor, so I use Hatari to provide a virtual one for me. Unfortunately it's one of those bootable games, so I can't just copy the files off the disk and put them into the emulator, I'll need to make an image so that Hatari knows it's supposed to be a floppy.
The game's on a single-sided disk, but my 1040 STF has a double-sided drive in it, so that's no problem. The Magic Shadow Archiver doesn't like the disk, though -- it croaks while trying to read the same track of the disk every time. Seems like a bad sign. But I haven't been able to find a copy on the internet that doesn't crash within Hatari, either. Am I missing something here?
