I can handle desoldering the BIOS SMD 29F400 flash chip, reprogramming it, and resoldering it back into place for people. I wouldn't want to handle replacing the Capcom custom SH2 CPU though, for the carts that need that done.
I have every good will to help people who cannot or do not want to risk changing the Standard CPU and reprogramming the BIOS. You just have to bring me the Cartridge and the Standard CPU. In Chile and South American countries
Tengo buena voluntad de ayudar la personas que no quiera arriesgarse a cambiar su CPU Estandar y reprogramar la BIOS. En chile y país sudamericano. Solo tienen que traerme su cartucho más su CPU Estandar.
