I don't know. I think people might like some games like Pop'n Music or KeyboardMania... but they might also like a Jojo game, maybe a fighter... DEFINITELY Famicom games... but I don't know. Would all depend on what people ask for.
Of systems I can bring I can do Sega Saturn, MegaDrive, Dreamcast, GameCube, PS1, PC Engine, N64, SuFami, Famicom, and PS2. Anything else more recent would be too far into the 'hacking'.
