Need help stacking original SNES roms
« on: August 06, 2019, 06:45 PM »
Hi, last year I bought a defective Ninja Warriors. After opening the shell, I’ve seen that the pcb was broken. So I bought Barkley Shut Up And Jam and switched the pcb’s. Ninja Warriors worked again but now I have the Barkley roms laying around.

My idea now is, stacking the two Barkley roms on a single Maskrom pcb. I know that there must be a 74LS00 somewhere between the roms, but I don’t know where.

I know that Barkley isn’t the best game, but I have some SVHC-1A0N boards that I don’t need anymore.

Can somebody help me on getting this game working?

Thanks in advance

You can track what pins goes to the ls using the pcb of Ninja Warriors I guess.

There are plenty of schematics of the cartridges pcb.

Hi, got it working  :) It took a little longer, to figure out how to wire the 74LS00, but it works now.
