@Jordi Nevermind... found it. I was wondering however why you did not choose to grab +5V and ground from the pin of the removed chip on the mainboard but instead took it from somewhere else? Is it 12V that goes into the 7805?

@Matth Unfortunately the NTSC version lacks of the RGB circuit inside the console, you cannot do anything.

Any chance of an NTSC version of this circuit?

Hi,

I also tested the RGB mod of gamesx in 2011. I finally manufactured my own PCB for it. On one TV it worked fine, on a modern LCD flat from Sony it did not. I found out that there must be something special with the CSYNC signal. I even used an oscilloscope to investigate the CSYNC signal which was in some cases not good enough.

Did you do any modifcations to the original gamesx layout? Would you be interested to exchange experiences?

Regards, Christian
