Hi!

I was wondering if anyone could hand me both the pinouts of the NES GPU and PPU.

reason is, I will try to get a hold on a (dead) NTSC nes for it's PPU and GPU so I can desolder them and solder them via switches on a PAL NES board.

kinda like this:

PAL chips on the board with power detached..... power on the board soldered to the middle of the switch and 1 leg to the PAL chip's power, the other to the NTSC's power leg. (while the other legs of the NTSC chip are soldered to the board.

So if the switches are set to PAL, the pal PPU and GPU it will power as a PAL machine.
And when it's booted in NTSC mode the NTSC chips will be used.

Reason for trying such a project:
I have some NTSC games which have graphic glitches (Mach Rider for example) so when I switch the NTSC chip, it will play normally.
