Did it load up with the neo geo cd intro logo before launching the game? Money came up with white screen with polymega bios. Worked fine with neogeo cd bios. Did you follow the instructions on how to make the folder on the sdcard?
Double-checked the card.. when I swapped in a different bios, it was misnamed. Put the real CDZ bios back in place with the right name.. worked like a charm. I'd never seen the NGCD bios startup before.
Your welcome. What I am hoping for next is that the Double Dragon game that is being worked on the Neo Geo will come to Neo Geo CD. So I can play it on the Polymega.
