Okay guys, I managed to find a guy in my home province who I am confident will be able to make me an Arduino cart reader if he purchases the required parts for the cart reader to have just SNES and Nintendo 64 support (this guy is Chinese; he runs this small store which specializes in products involving the use of the Raspberry Pi, and he has expertise in electrical engineering so I'm sure he can help me).
Now, I better ask a few questions so I can get back to this guy with the information he'll want to know.
First of all, what parts will he need to order to make the cart reader (including the clock generator for giving it compatibility with SA-1 SNES games)?
Second, can I have a guide to give him for this specific setup, please?
And third, if he is successful in building one of these cart readers someday, should I let him borrow my Super Mario RPG cartridge and one of my Nintendo 64 cartridges so that he can test it?
Thanks in advance.
