Good info about Linux. About to build a little DIY NAS and emulation machine in one, and had kind of landed on Linux (probably Mint) with a software raid (mdadm), and then intended to chuck the emulators on top. Guess I know in the back of my mind that some won't run, but, that's a problem for down the track. Looks like at least with a bit of tinkering I might be able to get MFME working!
