Hacking Flashing AGB Nintendo Official Flashcarts

Impossible...

Short of getting Nintendo's proprietary flashing hardware, I don't think you can rewrite on those. The FAS1 program you linked to (which I had no idea existed and am very excited about) seems to only be for FlashAdvance, just as your Flash2Advance linker is only for Flash2Advance carts. I imagine that every GBA flash cart would use a slightly different protocol. Even if you were to get your hands on an M3 linker, a EZFlash linker, or any other I imagine you'd run into the same issue.

As with any non-volatile storage medium you will require some form of hardware to flash it, be it a home made solution or an original flasher. If you really intend to use this flash cart as a storage medium, I would suggest starting with opening it and having a look at the circuitry inside. Chances are that you'll find off-the-shelf flash chips on-board, from there you can start looking for schematics for circuits you could use to flash information to it. Honestly though, I would leave the piece as it is and invest in a normal flash cart - chances are that you'll spend less in the process, get a better result and keep the somewhat rare collectible intact, not to mention that it will be a hell of a lot less busy work.

I see. Terribly unhelpful due to a lack of any markings whatsoever on the chips, requires further research, I'm afraid.

it's funny in the picture i noticed the chips are all black, no leters on them

but the OP still have a good rarity for collection

There are some people on AssemblerGames with these flashcarts, perhaps you could ask them?

Yep. Apparently I solved it. Dunno how but yay FAS1 flashes those nintendo carts now. took 6 years.

still kinks to work out. but closer.

Nice! Any information on compatibility as far as those carts are concerned? I know they have a couple switches/jumpers on the back to change capacities, do they efficiently cover the spectrum of GBA carts?

honestly, no clue i don't even have one. I've been building it and sending builds off. but i'm simply copying stuff over from Flinker. it doesn't appear Jeff Frohwein had any code for switching anything. just a "oh it's a nintendo cart, the blocksize is XX and it writes in YY chunks.

i still just use my FlashAdvancePro and Pgoshell, though GBA emulators on PSP have made that not really needed.

I understand. I'm going to hazard a guess that the switches only limit the capacity and don't influence the flashing process, although I can't imagine why you'd ever switch them to anything lower than maximum capacity.
