ps2 rgb mod
 

i have messiah fitted to a v5 with the rgb mod done now it only plays back ups in b/w with my rgb scart but its ok with my old ps1 scart can someone let me know the best setup rgb mod yes or no thanks

if it works with the psx RGB scart cable, then it's the cable that is the problem.
your ps2 cable is most likely not a true RGB cable.
