Earthworm JimThe DOS version includes Earthworm Jim as a playable character. This is because of the deal that Playmates (publisher of the first two Earthworm Jim games) and Takara (developer of the Battle Arena Toshinden series) had made: whileTakara would publish the Earthworm Jim games in Japan, Playmates would publish Toshinden 2 & 3 in the US, and also handle the DOS port of the original Battle Arena Toshinden.
RungoThe character select screen in the Japanese PlayStation version incorrectly spells "Rungo" as "Run Go". Presumably this was a mistake as the manual spells it "Rungo". This was corrected for the US and European releases.
