Homebrew Burn2Slot - Re-programm GBA bootlegs on DS

[VROdin]

hi VROdin, how do you get this ? and i find bus_1 worked for a burnCart .
u8 bus_1[] = { 15, 7, 14, 6, 13, 5, 12, 4, 0, 8, 1, 9, 2, 10, 3, 11};
u8 bus_2[] = { 0, 8, 1, 9, 6, 14, 7, 15, 2, 10, 3, 11, 4, 12, 5, 13};

and this: actually，only seq_0 seq_1 seq_3 is right for GBA_BUS[address], GBABF use others ,because it need address offset by *(vu16*)(addr|0x8000000)

u32 seq_0[] = { 0x555, 0x2AA, 0x555, 0x555, 0x2AA, 0x555};
u32 seq_1[] = { 0xAAA, 0x555, 0xAAA, 0xAAA, 0x555, 0xAAA};
u32 seq_2[] = { 0xAAA, 0x554, 0xAAA, 0xAAA, 0x554, 0xAAA};
u32 seq_3[] = { 0x5555, 0x2AAA, 0x5555, 0x5555, 0x2AAA, 0x5555};
u32 seq_4[] = { 0xAAAA, 0x5554, 0xAAAA, 0xAAAA, 0x5554, 0xAAAA};
u32 seq_5[] = { 0x1554, 0xAAA, 0x1554, 0x1554, 0xAAA, 0x1554};

Using GBA_BUS[addr] = data same as using (vu16*)(addr|0*8000000) = data. Its syntax sugar. I know only 1 msp55lv512 that work with bus_1. What u think about old intel cart support? I havent idea, cuz burn2slot v0.2 works. And can u fix some trouble for b2s, that u fix on your modification of gbabf with pullrequest?

I have already verified it, using (vu16*)(addr|0*8000000) = data ， need address offset >>1. and i found the intel main focus is on erasing small sectors.

swapTo and swapFrom need exchange. o.4.3

I've got a cart that isn't working correctly when flashed. When I try writing to it, the ROM gets corrupted. I believe it's Mitsubishi brand flash.
Also, does anyone know how to remove that black dot from the PCB in some of these things in case I want to add a battery? I already tried a soldering iron and a sharp object and can't seem to get anywhere.

edit: removed pic of a cart with a different kind of flash to focus on just one for now

Hey guys, i got today one of those 369 in 1 carts, wondering if i can solder a battery to it, and reflash the games? how?
gbabf sucessfully changes and boots the banks but can't dump the cart/banks. gba backup tool dumps only the first 32mb. i wish to make a full backup before i try to write with burn2slot

The chips are not equal to any cart i have found, here is a pic, any help is appreciated. Thanks

hi vrodin, i found the GB&GBC cart insert NDS ,it will mapping the rom to 0xa00000- 0xa007fff, so i think it is possible to burn GB&GBC cart on NDS .
maybe the NORFLASH need by 3.3v specifications。

I wanna make burner via gba for gb/gbc carts

I think that would be difficult - you can switch to GBC mode within GBA mode homebrew, but you are limited to the 32KB of GBA IWRAM/GBC WRAM. GBA carts are inaccessible, so you'd have to find the data to flash from elsewhere, like through the link cable.

Here's a code example for switching from GBA mode to GBC mode and running a custom payload.

I have these 3 cartridges that need batteries soldering, reckon they will work with burn2slot?

 

[VROdin]

guys, all the cartridges that are somehow supported work thanks to your luck, unfortunately, I can’t create a database with supported boards, since there are a lot of cartridges in which the Chinese used the same programming types. I hope all of you understand this.

Third maybe

If you are searching for a bootleg database maybe this helps: https://github.com/lesserkuma/FlashGBX/tree/master/FlashGBX/config

Oh nice job! I still haven't time make some progress on b2s

I bought a bootleg Yu-Gi-Oh gx duel academy bootleg, it works but i want to change the rom inside but the burn2flash says it's Unknown Flash.

Might have to use a GBxCart RW, or a Joey.

Yeah, maybe it can't detect because it has 256mbit flashsize i think

256Mbit is just 32MBytes right? That's the regular threshold for GBA carts, bootleg or not. Should read/write to/from it fine. But looking at the picture closer, on the left side it looks like maybe some lifted pads and a possible diode lifted. It's kinda hard to tell, but that entire board is a mess. Flux residue is EVERYWHERE on that thing, along with splatters of unknown substance on the chips, and some random red bodge wire? This thing might or might not be salvageable, or even worth salvaging to be honest.
