People often ask me why I don't support console emus in RD and this is one of the main reasons why. Eariler console emulators are good (nes/snes) about running games, but the newer one's run maybe one or two games correctly a piece. Even if the games are playable there are always serious graphical errors, particularly with n64 emus. My advice is either to run the u64emus for the arcade versions of ki/ki2 or simply keep playing them on your n64. I've yet to find a n64emu that plays all of my favorite games, one of which is ki gold.
