toying with the SIO

Post by legacy » September 5th, 2013, 7:17 am

hi guys
any asm source around to toy with the psOne & playstation1 SIO-uart port which does not use the BIOS at all ? I mean something that access directly the SIO registers.

I am planning to remove the psx's bios replacing the firmware with a bareboard piece of code, so the SIO will be my std-IO for the console.

You can check my SIO lib. It's not asm but it will get you in the right direction.
