    Been using a DS flash card for a couple of years now, but never messed with the GBA ones. I'll be using an EZ Flash IV on my GBA SP. Should I just use the same trimmer I use for my DS games, or do I need one specifically for GBA ROMs?

    Thanks

    Not sure if your current trimmer would even work on GBA ROMs. I use BatchGBA by our own TrolleyDave, which can also do save patching if you need it.

    Thanks, man. I'll grab that.

    EDIT: Let me ask you this: Will the client for EZ Flash IV still patch the games properly after I've already trimmed them using this program? I'm still trying to get a handle on all this. [​IMG]

    I think it would be safe to patch them, then trim them.

    The EZ4client app patches and trims the roms at the same time. You also have batchGBA and GBATA and a whole host of other tools like Flash advance toolkit (I would go on but GBA rom trimmers are about as prolific as DS ones).
    DS trimmers will not work as modern* DS trimmers use the file size found in the header which is lacking on the GBA (why you got overdumps and underdumps on occasion).

    *old style trimmers including the DS capabilities of the EZ4 used the same method as GBA roms.

    Hmm, doesn't the EZ4 client sometimes cause save erasure if you patch for a 1Mbit save? If only GBATA had 1Mbit patching.

    That could indicate that you've got some garbage data at the end of your roms. Either that or you tried to trim homebrew, which is not going to give you any extra space.

    Trimming on the GBA won't give you too much space back (I'm guessing 10-15% as a ballpark figure), but it won't hurt anything.
