Ive been looking into making my own reproduction carts. Im most interested in the NES and so far have found a lot of tutorials on how to do it, but I'm a little worried. Ive seen ones that use the basics like here but heres where I get nervous. Its the wires. I have no problem following his tutorial but my worry is it seems on other reproduction the wiring is different. For example that tutorial is for a MMC3 and I may want to do one on a SNROM. Will this tutorial be enough that I can figure it out on my own or is there a more specific one about how to make what with what.
