SweatyGremlins: I did look at the Rasberry Pi but I'm not too confident installing Windows 10 on it, it's probably easy but I Iike the idea of it coming already installed.
Draek: About the Raspberry Pi or similar: don't. They use ARM CPUs, so does everything running Android, thus unless the "old 2D games" you want to play are emulated console games (and sometimes even then; ZSNES' non-x86 ports are terrible), you really, really want an x86-compatible CPU.
Well certainly I wouldn't expect the Pi to run Windows 10. I mentioned it was mostly for browsing and simple tasks. A $25 computer, although it seemed to be a little slow for my tastes (
at least the Xbox Media Player), it does do native Mpeg4 decoding (
although some videos were glitchy so not sure if it could to AVC).
The
OS is free, although you have to partition a
SD card for it, and if you wanted more ports get a dedicated powered
USB hub, which can then feed power to the Pi. Unless you're emulating
SNES or earlier emulators, it probably isn't a good match.
All in all not a bad system that's tiny and low powered.
