Sounds like fasm used registers to pass parameters, is fixed set and order of registers been used? Such as eax for the first parameter, and ebx for the second one.

revolution: Primitive minded fool 10,000+ comments and not one single useful program to show.

Yep. I'm just posting nonsense constantly.

uart777, nop, you're nobody comparing to revolution's contributions to this board so shut up. revolution should delete your offtopic posts.
