To translate the japanese (gibberish) text in the file, try opening kumagawa_-2.cns as a state in Fighter Factory, and translate the real japanese text shown to see what each trigger does, the first one which is fvar(39) is his AI switch. For your other question, Touma will be getting an update soon according to otika himself, so please wait until the time comes.
Yup, that's right. Kumagawa got an update!! The game play is the same as the other version, but here are the changes: -Two new supers added in. One is a counter move that can be performed successfully if the opponent attacks physically. (of course it doesn't work on projectiles) And it can be used only if you have the plus screw activated. (Command): B, D, DB, D, DF, F, x / 61234x
Now the second new super is where Kumagawa turns his Book Maker into a long red lance, then to strike his opponent down. This super can be performed in mid-air as well. It can be used only if you have the minus screw activated. (Command): B, D, DB, D, DF, F, y / 61234y
-A new trigger in his Naked Apron super Some characters have a special naked apron sprite that shows when Kumagawa pulls off his HADAKA APRON super. This time the animation is modified. You can activate this in kumagawa_-2.cns on var(53)
If its not right however...
Brutal... Anyways, thats all for now, if you have any questions please reply to me on this topic. And enjoy this new update!
