    good day, im just a newbie here. I have lots of concern regarding GBA VC injection on 3DS,
    i keep on searching the net to properly load pokemon games (RSE/FRLG/mystery dungeon red/RS pinball)
    on 3ds directly from home menu, but because the GBA VC of the 3ds doesnt support the save structure of those games (128kb) lots of issue arises

    there are some patches, here:
    https://gbatemp.net/threads/tutorial-fix...ba.433266/
    but some problems still remain.
    another thing is, once the game is patched, the save data of that game would not be compatible on the unpached game.
    for the people who plays the game on both handheld emulator and on a pc emulator,
    and its a hassle if the save file is not compatible on each other...

    It comes to my mind that there are several GBA emulator on 3ds (mGBA & retroarch).
    i tested both on 3ds and for me, mGBA have more features at the same time have a cleaner look...
    unlike the retroarch, the bottom screen have lots of logs...

    but still the question remains in my mind if it is possible to modify mGBA.cia
    change its title ID and redirect a certain GBA file that is located on the 3ds sd card
    what i mean is this: currently the mGBA has a title ID of 1a1e
    then modify the mGBA multiple times, change the title ID:
    mGBA with title ID 9999 - directly detects a gba file on 3ds sd card: eg pokemonruby.gba
    mGBA with title ID 9998 - directly detects a gba file on 3ds sd card: eg pokemonsapphire.gba
    mGBA with title ID 9997 - directly detects a gba file on 3ds sd card: eg pokemonmyterydungeonred.gba

    so there will be 3 installation of mGBA with different game to load.

    just a suggestion... how bout make a GBA forwarder using mGBA engine with a PC gui like the one on NDS forwarder
    https://gbatemp.net/threads/nds-forwarde...nu.426174/

    hope its possible in future...
    thanks and have a nice day

    I asked for this in the Ultimate GBA injector thread, but it seems there isn't enough interest sadly :( (I hope this thread proves otherwise)

    If the CIA of the emulator supports arguments you could make a forwarder that passes the rom name in theory.

    yeah our request is ignored :-( looks like we are the only people inerested to this

    but im not loosing hope...

    someone asked the developer "endrift" of mGBA at mGBA forum regarding possibility of forwarder:
    https://forums.mgba.io/showthread.php?tid=2878

    and it was also addressed at the github page,
    https://github.com/mgba-emu/mgba/issues/713
    so that endrift wont forget the requested feature.

    and i replied the same request, but endrift not replied yet...

    i hope soon it will be possible...

    yeah, looking the logic its simple to do by making an argument on the app to directly boot a certain game on sd "if im only a developer",
    but im just a regular 3ds user, huhu...
