Hi All, Looks like Simon has indeed found a bug in SimCoupe - one of many no doubt. I'll really try to check and correct this in the next week. Chris's problems with SimCoupe and defender may also be related to the frame sync. mechanism used in the DOS version. On the UNIX version I just used a SIG_ALARM to get a periodic timer interrupt of 50Hz, but DOS in its wisdom programs the PC PITs at a lower frequency, so this approach is no use, unless the PIT timers are reprogrammed. This works in pure DOS but screws up in Windows.
I'll try to put up the latest UNIX sources on the web as well.
