Homebrew Burn2Slot - Re-programm GBA bootlegs on DS

[Clector]

There's photos of the 227E board.

By the way, I have a problem with the 22FC, some ROMs write but some doesn't work when booted with a blank screen, but I think that's normal. But there's an specific ROM that either clean or patched for SRAM doesn't finish writing it and gets stuck at 50%, the only difference it's that's 16 MB instead of 8 MB, but it shouldn't be a problem with the cart because the original ROM that was in it is 32 MB and it rewrites fine. What could be causing that problem?
Edit: It seems to get stuck at 50% with any 16 MB ROM.

it could be possible that it has to write the full amount of the cart
try opening it in a hex editor and doubling its size with 0's and see if it works
this is just a guess tho

It gets stuck at 25% instead, which is kind of the same I guess.

that seems to suggest its writing it half and half and changing which half it stores in, making 8mb go in one half and 8mb in another and so on(?)

just my guess tho based on how you say it

try an 8mb rom and see what happens

 

[Clector]

8MB ones work fine.

 

[MarioMasta64]

8MB ones work fine.

so if its indeed 32mb then yea it seems like something switches between 8mb memory sections during the writing process
idk how youd be able to tell how to make it do that but maybe markings on the chips might have clues at the very least you can write 8mb roms at the moment

Is this kind of repro supported?

Hi, i have a question, can i do this on gb/gbc bootlegs with gb/gbc backups?

ds can't play gb/gbc games - so I'm certain this homebrew can't, and I highly doubt it would be possible in the future

In the meantime, while waiting for a program to patch the ROMs to make them be able to save on certain flashcarts, could we read the ROMs from repros and upload those so others could flash them? Would it work? Would that make them save?

Did anyone have any luck with this approach? Repros I've dumped won't burn back, and won't open in emulators.
If the Aliexpress repro producers are able to save patch the roms so easily it must be a relatively simple procedure.

Soon i try make method for gba/gbc

I have 4 working boards that are not recognized by the tool (Error Unknown Flash ID 0000). Can they be supported in future?

I'm not sure can be 2, 4 add support yet, may be it can be modded with solder points for rewrite activation.

Thanks for your answer! Any idea what do I need to modify to test this? I can see that "W" solder point on second board is bridged, should I try to unbridge it?

And what about boards 1 and 3?

Any possibility to add support to this cartridge?

Specially for Pokémon Fire Red (getting white screen always )

Pokémon Fire Red (getting white screen always )

Are you able to flash the game completely? If yes, your cartridge is probably already supported.

You have to SRAM-patch the ROM before flashing for it to work (use the tool called GBATA to patch any games that use a save type other than SRAM; you can look up what saving method a game uses on advanscene).

After this it'll most likely start, but still, I doubt that this cartridge's SRAM chip will be enough for a Pokemon game to save correctly (it has quite a large save file), you will probably be greeted with save corruption messages each time you start the game. This is the case for both of my cartridges that work. But it may not be the case for your one, you have to try it yourself.

Just found this GBA bootleg cart for less than a buck, tested It with your app and it failed with an unknown ID 0000. Do you think it could work? Thanks!

yes it's work on test build, release it soon

first should work, may be it work on next build that will be soon

I'm no expert in spotting bootleg carts, but I know that this one gives a 0000 error on the latest build. No idea if it's familiar.
