Hi there! A friend and I are both looking to get into making some reproduction carts for hacks, etc. and I assume this device is a good place to start?

Are there any guides that walk you through what types of boards you need for each system and type of game? Google really seems to be coming up dry, maybe I'm searching for the wrong thing. Looking for a general direction to look as to what we need to buy and do.

Thanks!

My first functional repro took more than 2 years.
I think no one will give you that kind of information.
Google, read and learn, try , test, re-test etc. This is the only way.
On Google You can find many open source ready projects that can help you to learn or to speculate.
Goodluck

Here is my PCB "guides" for my private SNES reproduction :
