1. I've never heard of an "n64livecd" and suggest you use Surreal64.
Either version
Surreal64 XXX Beta 4.95 (newest but runs sketchy)
Surreal64_V1.0 (First one ever, runs great)
or just be like me, have both of them and just have them share the same rom directory so when one won't run a rom as smooth (ex. Beta 4.95) try the other one (ex.v1.0) and see how it go's
2.Well are their roms in the ROM directory of that cd that it supports?
