    Welcome to GBAtemp! [​IMG]

    M3 Perfect can be finicky at times. Make sure to format the SD into FAT32. If it is formatted in just FAT, you have to hit start to load a game instead of A, but in FAT32, you CAN hit A to load a game. Not sure if ROM size made any difference with that though.

    Also, are you sure it is M3 Perfect and not M3 Pro? M3 Pro did not have enough onboard memory for big GBA ROMs, but M3 Perfect does. You may have only the M3 Pro.

    Only other thing I could suggest is that you might have SD fragmentation. Copy everything from your SD to your computer, format your SD card and then copy everything back. Sometimes that can fix it. Do NOT use a defrag program on an SD card, it can damage them. Use the "copy, format, copy back" method.

    The best program to format SD cards is this:

    Hope that helps you.

    thank you for the answer [​IMG]

    I think it's not a "prop" but with these problems i'm not really sure now !!!

    But the format of sd card is fat , i'll format it into fat32 because i prefer to hit A, and i'm looking for segmentation with your method!

    i'll come back !

    NB: how can i say if it's a pro or not ?
