Hi Again Etienne, sadly my board doesn't work, it has a clock problem, do you have also the Main board Schematics?, didn't came with the manual? will be great to find where the clock signal is lost.

Thanks for all.

I'm not sure if it helps, but you should check Zacc Quasar's manual, the pcb is very identical.

Cool, can you explain, what was the problem and how did you repair it?

[ricky2001]

Of course 
The problem was that the processor and most of the board didn't get the clock. It was a bad 74S112 in 13b, just near the oscillator, It was easy in this case because this ic was receiving  clock but hasnt in the output, I change it and the board came to life, however then realized that it outputs inverted video just like nintendo boards so I'll make an inverter and try.

Here you can see the board



I'll tell you about the progress inverting video

Thanks

I've had a bad one of those before. Probably runs hot because of the fast clocks. In terms of the inverter, the simple inverter circuit that's in the Midway Lazarian manual is easily copied and works fine.
Regards,
Paul.
