Hmmmm... I'm not aware of why it may be crashing. I built it initially using the Atari 800 and then moved to 130xe but ensured it could run on the 800 still. I used the standard Atari Basic language (with a few ML routines built in for speed) to build and then compiled with the ABC compiler so that it did not require the Atari Basic cartridge. I am unsure of the Basic Rev used though I suspect that isn't the cause for the crashes. If I could learn to use an emulator I could likely troubleshoot. Also, there is a dungeon editor available for FOG as well that I never released. I think it was the first dungeon editor out at the time that I knew. I also invented my own home-grown compression/decompression technology that might be amusing to share.
On a similar note, I am new to this emulator thing so I need to do some research on how to do it. I'd also like to learn how to put programs/games out there for the emulator. I have massive amounts of software that probably nobody has or at least a small amount of people have.
