@spannernick1 This blog post may help since you basically want to detect a GPIO button press and then send a keypress (Select+B) to reset the game.

Nice work! I do love the look of the first generation Megadrive. Can you show some more details or close ups (if you have them) on how you wired up the original power switch. Did you cut the section of the original motherboard that had the switch on it away or did you de-solder the switch (or even just got with a new switch altogether)? As you know from my thread I'm planning on doing something similar with a MegaDrive 2.

@spannernick1 said in Pi2 in a Mega Drive 2 - advice needed:

Mayflash USB MD adapter

Ah thank you! Yeah I also prefer the look of the MD1 but my MD1 is still working so would feel bad about using it. Same reason I haven't gone for a SNES as I only have a working one and the price of even broken retro consoles seems to have gone pretty high these days!

I hadn't heard about the Mayflash USB MD adapter but it's a very good idea, did you have any issues with that working with RetroPie on the various (8-bit and 16-bit) emulators?

@rhj501 i couldnt find an option in picodrive for team play or multi tap.
