From what I have been able to research, the net yaroze program was much more significant in the UK than the states. From what I can tell, Sony USA wasn't very interested in doing the Net Yaroze program and canned it quick.
Assuming I could get a Net Yaroze (NTSC) how would I be able to play these games? I am assuming they are all PAL and won't work correctly in the states. Will I have to buy a UK PS1?
