Do you mean the one closest to the big marker "F"? Up is relative and all...just so there's no confusion...

Yeah, that's the one

gues nobody has seen such a megajoy II before but there must be a way to get the pinouts
there's no way by using my voltmeter or something like that?

Mega Joy 2? I own one! the pinouts are on doomportables.org

.... you should pay more attention to the entire thread. It's a PAL megajoy II that doesn't have a cart slot / isn't anything like the ntsc version.

Ben pain steakingly when though each pin to find what did what.

Nope, there are many veriations to the NOAC there is no standard really. He could try to do what Ben did but without a cart is will be a real pain the in ... to do so it might be easier and faster to just by a PAL version of the PowerJoy III.

I think one of the only practical ways is to use an osciloscope to see the pattern on each lead. You could ask NiN^_^NiN though, I know he did some noac pinout work awhile ago.

I'd buy another noac but its the only one I found in germany

Thx gannon I e-mailed NiN^_^NiN perhaps he can help

If anyone knows anything about the mega joy 2 pal post!!!

THX
