Awesome! I also used a bank switched bios on the ST-V instead of the multibios and let the Arduino control the region. That way it would save the settings I wanted every time on each game and didn't have to hold any button.
I did this exact thing with my ST-V cart with an arduino. Works great, but t does have to be powered on before you actually turn on the ST-V. Just some NPN Transistors and some resistors. I did etch a PCB that uses a Arduino Nano, but never tested it. This worked great on my ST-V and XXX in...
Wow, ok.
I never said I wouldn't release the schematics. I just ignored you when you asked me in my email. I told you in my email I would post an announcement at some point. That should have been a clue that I wasn't ready to announce anything.
I will be open sourcing my NBM project so the...
Have you guys given any thought to what I mentioned earlier this year on ng.com? The ability to load several roms in to virtual slots. Hitting a slot select button will cycle to the next game, and reset the neo. I did this with my arduino and a XXX in 1 cart. It would be a great way to have...
