The loop routine is ANDing the IN DX value with 9 and then looking for bit 0 (1) match, or reloop. Guess that's an out of vertical, out of horizontal status check. Dunno why it's a problem under Qemu, maybe a BIOS versioning issue. I suppose it could be an artifact of GDB breaking into the program, but since Stargunner is an infinite loop at that point, and this would qualify, I'm thinking it's real. ------------------------------------------------------------------------- Using Tomcat but need to do more?
