Psx for the win
I just kinda skimmed it right now, but does it go into technical specifications? I'm curious since it mentioned the board can accept actual PS1 chips if it would need an official PS1 BIOS.
My (incredibly amateur and limited) understanding of the PSX architecture tells me that it would need some kind of BIOS, but this is the first search result for "open source psx bios" and it seems to work for most games, according to their compatibility list . It's possible that other, more developed BIOS replacements exist.
This is a cool as shit project
Amazing. So cool to see.

Hell yeah. Always good to hear.
That said, I need a PSOne ODE. My stack of PS1s still run fine.
Man those are some CHUNKY ICs.
