man i cant stress this enough
take EVERY XBE file from the game folder on your xbox and bring them to your PC,, patch them,, ftp them back and overwrite the old ones.
use ONLY 4977 bios, make DAMN sure ALL igr are off in the evox system settings menu.
if the game sTILL aint working then its either a bogus copy or a bad download if you downloaded it, which,, well we aint talking about that.
mine works fine and my xbox is the one it should be giving the most trouble.
1.0 xbox
bert and ernie reloaded w/ PBL 1.3.5i
ALSO
make damn sure your evox clock is correct.
are you using like a madcatz controller or something ? try a regualr xbox controller.
take out all your memory cards delete the save game that IS there,, even if you dont play the game the game creates a save file.
delete the cache files on your E and xyz drives.
if it still aint working there is something about your xbox thegame dont like.
