Thanks. I have Fatal Frame and Captain Rainbow in NTSC-J too, but all I had to do was use RegionFree and BrickBlocker on them. But Tatsunoko Vs. Capcom is a different case. =/
I've looked at all the topics on this game, and if I understand correctly, I HAVE to use a backup loader like Gecko or Wiigator? Because I can't get it to work with just my modchip...
