Just ordered a Neo Geo Mini (international version) from Amazon.com, as it is dirt cheap ($45, whew) and I figured might be interesting to mess with, and if I end up not wanting to keep it I could always give it away as a Christmas gift.
I was wondering if anyone has already opened one and looked into the possibility of sticking a MiSTer inside? I'm not too hopeful about it, as it's probably too small and the screen probably uses some weird connection, but hey, who knows?
