New Post: Can someone look at this code

Capcom Vs SNK Pro:

wait for flag at 8007d530 in an infinite loop after calling firstfile(). The flag is set in event handler.
if firstfile() does not return NULL, the game will call card_read() which delivers the event -> call the event handler -> set the flag -> exit the infinite loop.

with real BIOS firstfile() returns NULL as well, however the event handler was still called for some reason. Need more investigation.
