    Hardware GBA Bootleg GBA cart with Genesis on a chip

    Interesting find. Bootlegs can get pretty bonkers.

    SuperFW: a (very much WIP) supercard firmware

    Official GBA games use up to 32KB SRAM. As far as I'm aware, the Supercard doesn't have any mechanism to switch SRAM banks. Some flashcarts like EZ Flash IV do, by poking a particular MMIO register. Other cars like Everdrive emulate EEPROM & Flash commands for games which use those chips, so...

    SuperFW: a (very much WIP) supercard firmware

    The size of the chip doesn't matter. SRAM addressing is restricted 16 bits (64KB) as a hardware limitation. You need banking to have more SRAM capacity, but as far as I can tell there's no registers mapped for this purpose.

    Homebrew SCFW: Custom Firmware & Kernel for Supercard

    Sorry I haven't been posting very much, work has ramped up and I'm very busy lately.

    SuperFW: a (very much WIP) supercard firmware

    Not having any of the carts which have been bricked, I don't know what the issue with flashing is. It seems easy enough, but I guess in practice it turns out a little different. Clones are definitely using new flash ids these days, because they aren't being recognised by the OFW installer...

    Awesome work!

    Homebrew SCFW: Custom Firmware & Kernel for Supercard

    A lot of people seem to be having issues with flashing the firmware lately, so maybe avoid this until I can figure out what's going on, or unless you have another way to unbrick it. The downside is, you can't use SDHC...

    Homebrew SCFW: Custom Firmware & Kernel for Supercard

    Well, when NDS mode is implemented, that should be a normal .nds file you can boot in any way you like.

    Homebrew SCFW: Custom Firmware & Kernel for Supercard

    I have loaded the kernel multiple times using YSMenu on the NDS side. I think maybe TWLMenu's automatic patches screw it up.

    Can you attach a screenshot of the SCFW folder on your SD card?

    Homebrew SCFW: Custom Firmware & Kernel for Supercard

    Is the folder scfw containing kernel.gba in the root of your sd card?

    Homebrew SCFW: Custom Firmware & Kernel for Supercard

    So, I took a look at the new Supercard which gives the "flash id cb2a" error. It looks like this is already completely compatible with the existing flashing code, and is even recognised as a compatible chip by SCFW already. Only the original firmware does not recognise this chip. Since...

    Emulation Help: Corrupted Save EZFlash

    It's probably a save banking problem. Pokemon GBA games use a special method to access more save memory than usual. Vanilla Pokemon games use this to save backup copies of the save file, so saving multiple times can ensure that at least one copy is saved correctly. Unbound is known to remove the...

    Homebrew SCFW: Custom Firmware & Kernel for Supercard

    Just checked a spare Supercard I own which I bought about 2 weeks ago which also has flash id c2ba. Looks like these are becoming more common in the wild.

    Homebrew SCFW: Custom Firmware & Kernel for Supercard

    I don't know yet why that happens for you. And that's unlikely. The flash chip only stores the firmware data, and using a different flash chip should only matter while trying to install the firmware.
