The library of downloadable PsOne games in Japan is humongous. Sony Computer Entertainment announced there are over 600 titles in the Game Archives section on PlayStation Network. TurboGrafx-16 games and SNK’s online enabled NeoGeo ROMs account for part of that number, but the bulk are PsOne titles.
Our collection in North America is… considerably smaller, but growing thanks to MonkeyPaw’s digital imports, the occasional Squaresoft classic, and the upcoming Sega Genesis titles.
