    I'm sure this has been touched upon a few times, but I'm having trouble finding definitive information. Just to note, I'm completely new to this particular thing.

    I plan to buy an EZ Flash 3-in-1 and flash a ROM to it, then move the innards of the EZ Flash 3-in-1 to a normal GBA cartridge and use it as a single game long-term. After patching the ROM, however, the file size is 17.1mb. I understand that up to 16mb can be stored in SRAM and anything between that and 32mb is to be used with NOR.

    So, assuming I use NOR, will my progress save to the battery when I use the normal save function within the game itself? Does it more or less function exactly like a legitimate Gameboy Advance game?

    Also, does my slot 1 card have to support GBA Exploader to do this? Or can I buy a cheap TT card?

    Thanks!

    Edit: Apologies if this is the wrong forum.

    Use link here: http://gbatemp.net/threads/how-to-tell-which-version-of-the-3in1-you-have.130659/

    See Q&A section to answer what PSRAM, NOR and SRAM is. And answers any issues you will need to deal with NOR and your save data.

    Any ROM larger than 16MB is loaded into NOR regardless if it is patch or not.


    Any GBA ROM loaded to NOR acts like a legitimate GBA.

    Appreciate the response.

    In any case, I've stumbled upon a problem after receiving my 3-in-1 and purchasing a cheap used GBA game from eBay. The 3-in-1 innards will not fit inside of the GBA case, even after removing the long plastic bar that is the obvious obstruction. The chips on the back of the board and the battery on the front make the 3-in-1 too thick to fit in a normal GBA cartridge (with the pins in the proper place), yet, I've read countless posts where people claim that they successfully swapped the 3-in-1 innards with that of a normal GBA cartridge.

    It seems that the back of this particular GBA game's case was not made to support any chips on the back of the board and I'm afraid trying to hollow it out a bit more will result in supreme failure. Does anyone know of any cheap games that have chips on both sides of the board that would likely fit the 3-in-1?

    I'd also like to know: is it possible to purchase the EZ Flash IV, flash a game, and then remove the SD card slot entirely from the board with no issues? Would it function just like a normal GBA cartridge if flashed to NOR?

    Thanks again!

    P.S. I was shipped EZ5C3 (3in1+).

    Point a weapon at me and I might be able to get something done as far as autobooting an EZ4 NOR, I even did something like it many years ago as a test. In practice it is not really going to happen.

    Fitting a 3 in 1 innards in a GBA case. Most of the time it will involve a blade and some sanding.

    If your planning to put it in a GBA/SP/micro without replacing the shell with a GBA shell from a throwaway GBA game, you have to shave off the overhanging plastic and using string strong enough to survive lots of stress like dental floss.

    Inserting it into a GBA/SP/micro will end up looking like this. This is why you need a pull string.

    Your other option is to use an action replay if you have one.

    It doesn't take much either way.
