rhythm of paradise problem please help

Hi I hope I have posted in the right place, I downloaded rhythm of paradise nds and it loads ok, and can start to play the first level but it does not save, and something is missing on it, because I transferred the file to my friends r4 chip and when she plays it, it is fine, and she can save, on it you can go to the cafe to play other levels on hers, but on mine its blank. So any ideas its the same file so why does hers work and mine dont. Hoping you can come up with the answer from a very frustrated Gremilin. Thanks. :(

Are you using an R4? Read the Common Issues.

Hi yes i am using the r4 chip, I downloaded dslazy and arm 7, I used it on rhythm paradise grand theft auto china wars, but both of them the game starts, then cannot play any further. Any ideas. Thanks.

Do you have the latest firmware etc.? Are the R4 cartridges a different version between you and your friend's (III, SDHC etc.)?
