So i have got some cps2 roms working great.... & im hyped to finally have hacked my PSVita , im just curious i can only get the cps2 roms " WORLD " ones working .... not any Usa ,,.. Euro ones work which is a shame because there's tons of titles i want..... So am i doing something wrong? Is there a Region Switch in retroarch? Or is there a way to convert them to " WORLD " Roms....? Any Help or Advice ...Would be Welcome !
