I just tried this out with a brand new bootleg I got from Aliexpress. The chip says it is a "hy62uf8100."

Your app does the following:

1. Detects it as a "Spansion." I did some quick research, and it says it is a Hyundai chip, but I could be wrong. Literally did 5 minutes of research.

2. Erases the bootleg

3. Writes the rom. It takes a while to write, which I imagine it is normal behavior.

4. After the write, it reboots into GBA mode, launching the game. However, after the GBA splash screen, all I get is a white screen.

Here's an image of the board if you need it. I'd be more than willing to help test this out.

[Edit] I was able to get this cart to boot Fire Emblem: The Binding Blade, but it wouldn't save. Of course, because of the way bootlegs save games, and me not knowing how to set that up properly. Still weirdly, I'm unable to get the original game back onto this cart (Wolfenstein 3D).

[Edit 2] I was also able to get Mega Man & Bass to run. Wouldn't save, of course. After patching Wolfenstein 3D to use SRAM, the cart was able to boot the game.. without being able to save. I know bootlegs save by essentially overwriting their flash memory, but I don't know how to set that up just yet.

Most bootleg cartridges uses 128kb / 1024Kb SRAM for saving (MOTHER 3 bootleg carts uses 64kb / 512Kb FLASH though), if the bootleg cartridge didn't have the battery soldered, the ROM in the bootleg cart is modified to save in the ROM itself instead.

Flashing unmodified or GBATA SRAM patched ROMs in that bootleg cart requires to solder a battery on to make saves work properly.

I think about rom patching, but don't know how i can do this on runtime while rom writing. Maybe it'll be app for desktop in future. Now i try support many cartridge for reflashing. Code that I can borrow from other projects is almost over, but it does not help to flash a lot of cartridges that my testers have. I have plans for this project ...

There either seems to be a bug in the code or it takes a rather long time to write roms bigger than 16MB (I didn't try anything larger except 30 and 32MB roms), I just checked out the datasheet for mx29gl128ehmc-90g and it's 256MB so storage isn't a problem

Do you mean Mbyte or Mbit? Mx29gl128 has 128mbit it is 16Mbyte.

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?

On next step try to enter to CFI mode, for chip size detect and check buffer writing possibility and check size of this buffer.

Great software,a question regarding from this software:

Instead reprogramming a gba bootleg,can we do the same features from Slot 1? I have a bunch of original r4 so it will be nice to do some burning the chip and changin their firmware for better capabilities.

I tried with a 22FC with a "Sharp" chip, some games worked to write but others didn't, getting stuck at 50.
Also I tried a 227E with a "Fujitsu" chip but it gets stuck at "Writing 0", it happens with all games, even when trying to rewrite the original one it instead gets stuck at "ERACE 25", any ideas why?
Had two other bootlegs, but they seem to be a FLASH ones that the program doesn't seem to support.
Also is it possible to patch an SRAM game to EEPROM?

What about "Erace 25" I will fix it on feature. Take photo of 227E board. I think it's problem with sector erasing...

Anyone know if there is a gba ROM patcher that can convert saves to different types such as flash and FRAM (NOT GBATA, that one can only convert to SRAM)?

NTRboot flashes firmware to flash carts, but the original R4 is not supported.

https://github.com/jason0597/ntrboot_flasher_nds
I have two original r4 and 1 acekard 2i.Thanks to point the software,but it sucks doesnt support the original r4...it would be great to flash it to give another opportunity of this oldie cart,also with flashing getting support for 32gb microsd...

    i used to go out to the recycling center every couple weeks and look at the crts and other electronics people would drop off. Usually screens were broken or severely scratched from being tossed around. Did find a good one here and there, but never anything like a 1080i widescreen crt.

    Is it piracy if it was released for free? Not in my opinion, but I also think it's not piracy if buying it isn't owning it, and it's not piracy if you can't buy it from the original creators anymore.
