Guitar hero decades problem

My guitar hero on tour decades (E) from diplodocus ( or something like that ;) ) doesn't work at all.
The first time i had the could not acces data problem. Did the arm 7 patch and that message never ever appeared again.
But now i got an other problem, as soon as the r4 is done loading the game, both screens turn white and nothing happens.
I updated my r4 after that to 1.18 if im correct but still no game coming up...
i got the guitar grip from the first on tour game so that shouldn't be the problem...
I hope someone can help me out coz i really want to play the game and i ran out of ideas :9Thanks for readingPS: Great site :D

Try using YSMenu. Search the Forums for the link I provided, I can't honestly be bothered finding.

Ok i downloaded the ysmenu, formatted my r4, copied the ysmenu folders into the card. copied the old games and saves back, but still, guitar hero won't work, all other games do work...so now im really confused.
Mayby i did something wrong while i applied the arm7 patch, although i can't remember if i have done something wrong...
Is it mayby possible that someone could create a prepatched guitar hero on tour decades rom? I would really like that coz i don't know what to do anymore :(Well thanks anyway for your help anandjones :)

Make sure to use an arm7 bin from a newer game.
