Are you by any chance using a 32 bit version of zsnes on a 64 bit distro?
Yes I am. AFAIK there's no 64bit version of zsnes available. At least that's what I've read in the zsnes forums and that's how Gentoo is building the software (as 32bit app).
You need to build and install a 32bit r600g 3D driver as well.
