Hello
I stopped C developing because as I knew how to do some things in C but there was always one problem that annoyed me a lot, I stopped developing on the Neo in C and instead switched to 68k assembly language. But, here's my problem: my program works perfectly fine with an original MVS BIOS, but when I try it with an AES BIOS or an Unibios, then I just get a black screen and MAME debug option shows that it does some stuff then loop over this:

C116D0 | cmpm.w (a0)+, (a1)+
C116D2 | bne $C116DA
C116D4 | cmpa.l a1, a2
C116D6 | bne $c116d0

If someone has a clue on what happens here (@blastar ?) it would help me a lot.
