Making a snes cart...The cart has 8k ram on it, but the game requires 32k ram....everything else matches up that is required. Could I just switch that 8k ram chip out with a 32k ram chip, would that work, or would there be more required than that? Thanks!

I doubt it, but I'm unsure how SNES ciruit works. You'd have to make sure the cart does not use the positive CE on the 8KB RAM (it should be connected to VCC), and if that's the case you should connect the two highest adress lines of the 32 KB RAM at the correct place (no idea where it's, I'm not really in SNESdev).

If the positive CE is used then you'd probably need some NAND gates or something like that to combine both CE and /CE to only one /CE.
Life is complex: it has both real and imaginary components.
