Sorry if this is the wrong place to post this, but I got Virtual Boy emulation working (on a Raspberry Pi 2) via compiling mednafen-vb-libretro and also via mednafen-0.9 from the ‘Jessie’ Debian repository.
I actually got 3D to work with my TV with the plain mednafen version, but not from within the emulation station frontend.
I also would like 7800 emulation, so I’ll be working on that at some point if someone doesn’t get to it before me.
