I don't think TUMIKI Fighters is new, I'm sure I saw that there when I looked at these games when the 2 ports were released. At the time the author of the ports was mentioning that the coding for these other games was in a different language, or something to the like, and that it was a LOT more effort to port them. He said he was going to have a look at it maybe one day.
Agh, here we go, some are in the D Programming Language. In fact, it looks like all the others except the 2 already ported are in D, else I'm sure we would have seem them by now.
XDelusion, I can't believe you're not up with the play on these two excellent ports.
