If I remember correctly the ROM checksum is based on the second 1K of memory in the cartridge. Thus for small programs there's a good change it'll conflict with another checksum and the properties for that game will be used :-( Usually this means the wrong bank-switching method will be used and Stella crashes.... Luckily, this problem will be fixed in the next release of Stella. The next release uses a 128-bit checksum calculated on the entire ROM image. So far I haven't seen any conflicts with this approach. > But I think using PCAE 2.0b would be a better choice, since > it also has a nice debugger.

Hopefully, the debugger will make it into the other ports as well. Brad P.S. If there's any feature you'd like to see in the next release of Stella let me know and I'll see what I can do P.P.S. I've handled the DOS port of Stella for the last few releases, however, due to my lack of time I'd like to find someone else to take care of it. If you're intested and have some DOS programming experience let me know. -------------------------------------------------------------------------- Bradford W.
