OK, I finally managed to have the sound wired too, so I can now really enjot my HNG64. Buriki One is absolutely great! It's so accurate and well realized that I can't even call it a fighting game like the ones we know... it's a sports game! Every martial art is super-dateailed and perfectly realized... and the matches (especially VS ones) are intense and need a lot of skill and timing, just like real martial arts matches.
A HNG64 is worth owning only for this one, superb game!
