SDD-1 (Star Ocean)
SA-1 (Yoshi's Island)
Super-FX (StarFox)
DSP (Mario Kart)
Only DSP chips can be played in copiers with either a built-in DSP chip (like my PFQ+) or a DSP cart (DSP adapter or cart with DSP chip onboard). HOWEVER, as mentioned before , there are different "versions" of DSP, and they're aren't compatible with each other. So, If you use mariokart as your DSP adapter, you _may_ be able to play one or two other DSP games, but probably not (I'm not sure how many different DSP chips there are). So, it's pretty impractical to try to play dsp games.

> According to some texts Star Ocean hasn't DSP, but other different chip. Btw, in the case it was one DSP... do you have more than 64 mb in your copier in order to play it? :)
