Atomic PI emulation setup notes

I mostly game on PC, but at one point I set up a retropi for emulated console multiplayer. Mario Kart ran pretty well (sprites and all!) but BattleTanx wasn’t performing. That’s the N64 game that I probably played the most of, and it’s cracking good multiplayer, even at the 9FPS that the Pi could manage. That was sort of the experience I was after though, so I went looking for something a bit more powerful.

Enter Digital Loggers. There was a kickstarter for a board called the Atomic Pi. It’s about the size of two Raspberry Pis and has an Intel Atom processor rather than the Pi’s ARM core. It’s still smaller than any one of the various consoles I plan to emulate on it, which is a nice bonus.

For this setup I got the Atomic PI with the small breakout board that provides a (more or less) standard adapter plug. I’m using this power brick and this multi USB hub (because there is only one USB port on the board.) It comes with a soldered-in EPROM you can boot from and write an OS to, but OSs on the eprom are painfully slow so I would recommend installing your OS to a MicroSD card like you would with a RasPi. I’m using Lubuntu, and it’s performing pretty well considering the big screen it’s on, I’m sure your favorite lightweight distro will also do well. You’ll want something that ships with a desktop for emulation though

Back to Battletanx: To get it running in Mupen64Plus (which you can install with apt along with a barebones GUI for opening ROMs and managing settings) with Rice video you need only change the config in one way:

ScreenUpdateSetting = 7

There are some glitches (the button that makes the flame tank fire sideways and makes the FLP-E tank flip get stuck) but it’s mostly playable. And Mario Kart still runs great.
