Im a newb when it comes to R4 usage but for some reason I think they hate Pokemon games. I have an R4-III Upgrade Revolution DS that uses SDHC cards. The cart is currently updated to the latest v3.08 system. I first put it on the sd card, put it in its on folder with the file and folder named the same thing. Every time i would scroll down to the folder it was listed in and go in it, the cart would freeze. I then took the game out of the of the folder and put it in the root directory and it works fine. So i thought maybe the cart was playing a trick on me and hates Pokemon. So i renamed the folder P.Ranger Shadow of Almia and put the rom inside without renaming it from when i extracted it from the folder. Restarted then tried to play it. Again it froze. I have no idea why it does it on this one game and not others. Someone please explain this anomilie.
