Sega Genesis > Arduino Comunication

Post by cloudstrifer » Sat Feb 02, 2019 2:38 pm

Hi!

I want to use an Arduino to interact with Sega Genesis cartridge, is it possible?
Arduino will be read only, access 8 or 16bit of information.

I will set a value in game and Arduino will read that and generate a bip or show something in a display.

My idea is a game that will interact with external hardware.

Thank you!

You can expose pins provided by the arduino in some range of addresses, that works for sure, but you have to provide a decoder in the cartridge.

Also you can use any of the 3 or 2 controller ports as interface.

And perhaps toying with the DTACK signal on the cartridge port you can even exchange the cpu, not sure how the address arbiter will react, not sure if it's possible.
