I have one of these which I have played all of two minutes before deciding that the included games aren't worth playing for more than two minutes:
Despite already having piles of unfinished projects, I'm kicking around the idea of getting some real classics on it.
From a little bit of research, here is the direction I'm thinking of going:
Pi Zero - as long as early 80's classics are playable, I'll be happy with it.
I don't think a full size Pi will fit.
320x240 Screen with A/V input - From what I read this still utilizes the GPU whereas one driven by the pins on the zero would not, and would require software installation. Is RGB an option? I have a spare mini slg scanline generator kicking around (would require higher resolution) Not sure which size screen will fit yet.
Kind of deciding whether I want to take on the project or not at this juncture.
Minimus AVR programmed using KADE software - I assume this is easier than using pins on the Pi Zero? The controls on the mini arcade are already on their own PCB, so it should just be a matter of wiring it to the AVR. I already have a couple of these in a parts drawer.
The little arcade machine currently takes 3 AAA batteries which will give me 4.5v.
Is this enough, or does it need to be taken up to 5-6v?
I have no experience with Linux or pi. I'm counting on just downloading a card image and having things be fairly plug and play.
Any advice appreciated.
