Now, I know I had this problem on my old Naomi 1, but that thing was crappy Basically, it has a Naomi GDRom error if I dont have power to the GDdrive, then Error 22 with power Using the correct cable now, Capcom IO, and a Naomi 2 board. Think its because it needs a slight tweak on the 5+v line?
Edit: Definately a problem with my Cable or GDrom drive. What cable exactly is it? Dont want to buy the wrong one
Error 22
no the BIOS from a Naomi 1 is no useable in a Naomi 2 or vice versa.
