I have a fully working Sega whitestar cpu board 237-0176-00 revision D (also marked 520-5136-00 revision D) that I have tested myself in trilogy and worked fine. Problem is when I try to use it in Tspp or Austin powers (after I swap all the roms) it won't boot up. Those games normally had revision E for cpu. Do I have to swap pal chips, jumper wire, etc. please help.
