Swapping works, but it's not always worth doing it... I killed my PSX once by doing it
and hopefully, a friend who just thrown his PSX on a wall was ok to give me working parts
I needed. Also, the swapping methods depend on the BIOS version
Very old PSX can do it easily, later ones requires multiple swaps per boot and better timing
Play your PSX games on your PC, HW accelerated rendering and inffinite memory card capacity are cool features
EDIT:
"there are also development versions of ps2s that can boot burnt media, but i think that they need certain developer prgrams to do this and also are not typically available to the public."
Like the Net yaroze version of the PSX?
