i just bought GHOT for ds, and shortly downloaded it on R4 so i could play multiplayer, along using the "no grip error disable" and "ABXY custom frets" cheats. but when we start multiplayer and i host game. my friends ds just keeps saying no host. i had to download US ROM instead of EU wich i own, since US works with "no grip" cheats while i couldnt make EU version work. is it because of the regional Game difference, or is the game just not MP compatible with the current R4 1.18 firmware?
