incredible hulk

is anyone else having an issue runing the incredible hulk ds rom? keep getting a message "the save data could not be accessed, please turn the power off and re insert the DS card"

Have you read the Common Issues? Do you have an R4?

We have the same problem with this game

No one will wave a magic wand sadly and make it happen for you, but I found this and followed the first link and it worked for me
Good luck
