(Examples of programs that do not work: Afterburner, >Blood Money) Who knows what they're doing, but I can tell you for sure that some things will not work on some monitors. The difference between 50Hz and 60Hz can sometimes be without a cure. There are several different 50/60 switchers available in the public domain. I've found one that works great, and is only about 500 bytes long. If anyone is interested, let me know. This will help with a lot of the problems, but not all. Where I work, we've fixed about 5 or so games from Europe with it, but some, like Blood Money, just will not work on some of the 1224's out there. If anyone is interested in a program like this, let me know and I'll post it to comp.binaries.atari.st.
