PS1 RGB Fix
 

Could anyone tell me how to modify my ps1 scph-102. It has a built in lcd screen. The picture 'rolls' on most games.

I understand there is an rgb fix but cannot find any for this particular model. Thanks.

I don't think an RGB fix will help sounds like you need to patch the Video Mode on
your games. It is a PAL PS1 right? Built in LCD?? Never heard of that before, it is
not a 3rd Party brand that plugs in the back? If it is imported from Japan or US it
is probably an NTSC format display and you are trying to play PAL games.

There is a PAL-NTSC Patcher convertor called Zapper 2K that works on most games,
you convert the CD to NTSC and burn it, you will also need a MOD chip installed.
You might find a POT adjustment or something if you take apart the LCD Cover to
change the LCD Video Mode but I doubt it.
