I had the same problem and for me it worked to remove the directories GBA_SAVE and GBA_SIGN and after that everything worked fine for me. SO give it a try I would say
How it is done I don't know but I removed all the directories (GBA SAVE & SIGN) from the R4 card start up again the GBA EXP loader and now it is working.
Can somebody help please.
After the use of the GBA EXPloader just playing some GBA games it is not possible to use the DS browser. My rampack is not recognised.
Is there a way to check the RAM pack?
