I recently purchased a Naomi that came with a copy of 18 wheeler. It boots up and loads 18 wheeler and any other PCB fine. My problem is I bought this Naomi to move my USA h bios and netdimm so my other white Naomi can go back to being dedicated to marvel vs Capcom 2(I believe my mvc2 set was from the same kit). The 18 wheeler Naomi will only boot with 21577 d bios. I ve tried 21576 d and 21577 h. I have 2 other chips with 21577 d that also boot on this Naomi. I can swap any bios chips into any other Naomi I have and they boot. Why is this Naomi so picky?
