Naomi Error 02 - This game is not acceptable...

I'm testing more GD-ROM games with DEmul v0.54 AW and I've noticed that a couple of them, "Capcom vs SNK Millenium Fight 2000 Pro (GDL-0004)" and "Street Fighter Zero 3 Upper (GDL-0002)" produce this error message.

I'm pretty sure I've followed all the right steps when it comes to converting the CHD into a BIN, and also changin BIOS region doesn't seem to help.

Any ideas?

Alright, found out by myself. When the Naomi bios returns a Error 01 or an Error 02 message that's because the BIOS region is wrong. Still have to find out which is the right one for "Street Fighter Zero 3 Upper (GDL-0002)", but I got all the rest of games working with some tweaking.

I hope this region detection becomes automatic with next releases, because it's a real pain in the a*se.

Thank you, it was driving me nuts.

Try exiting the program after changing the BIOS, then restart. I think the emulator won't apply these kind of changes unless it's restarted. Yep, that's annoying.
