The game works with Supercard Lite, use the software 2.56
OK, grabbed 2.56 again, patched it with that (restart, trim, reset, patch cart : high) and it no longer crashes when I go in and out of the map screen. Gonna play for a little while and see if I can force a crash by repeating stuff that crashed the game previously.
EDIT: Spoke with blue guy again and got a crash (Never crashed on that previously) Gonna try it with no trim, no reset and CPA: Low instead.
EDIT2: OK, no crash first time I spoke to the blue guy, then spoke to him again and it crashed. Still no crash when buying map, exiting map screen, or pressing start. Should speak to the blue guy activate the mission, save it, then repatch with 2.56 I guess
EDIT3: OK, managed to get a crash coming out of the map screen again, haven't mamaged to repeat speaking to the blue guy with no crash
Happy to wait for the English version, hope they can fix it by then. Back to playing Bomberman Land, which has got me surprisingly hooked
