Does Captain Tsubasa on PS2 have an English version or English patch? This game is great but unfortunately I don't know Japanese at all.
No. And it looks like there hasn't been any attempts by fans to rewrite the script for the game (at least not that I could find). PS2 games are usually not quite as easy to 'patch' as, say, a PC, NES, or Gameboy game.
It does look like you aren't the only one who wants to see it though.
