Homebrew SCFW: Custom Firmware & Kernel for Supercard

[darkshooter116]

Yeah just ordered another one. For the future, do you recommend just using the kernel file to run the game? Without flashing the firmware?

What format is the sdcard? Have you try with another card? And also are you on a DS?

The cards are on FAT format ( not fat 32) . Yes I have test with 3 différents card . That is on real Gameboy Advance ( the first not sp)

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...

Hello Metroid,

I'd like to report that SDHC cards(128 GB - SanDisk brand) work on the super card SD with your custom firmware.
So far, it works like a charm. The issues mentioned previously might be related to the sdcard itself. Based on my experience, flashcarts behave differently depending on the brand of the sdcard. Either that or the file is corrupted.

Here's the hash checksum of 0.5.2's kernel.gba straight from your github:

• MD5: 1351671B7C7FE79D2E030E1225130EA7
• SHA256: 39D4B88A2483247C43C5D2BA3D5FA6C8E9CEB1BB934FFD17EC4E230B8EB3DE06
• CRC32: 49628D0E

I don't think that's part of the scope of the homebrew project itself...

Typically, just copying the sdcard/TF files to another directory/storage medium is in itself a backup already since the firmware's kernel is designed to be plug-n-play.

• As long as the directory "scfw" is found in the root directory of the card and the kernel.gba file is found inside it, the flashcart will always boot.

You can then just copy that onto another sdcard that's using a FAT32 filesystem.

This is what my sdcard looks like in Windows vs what's shown on my gamebox once inside the flashcart.

EXEQ Gamebox SP:


Windows:



Notice that I removed the firmware file after flashing it on the cart. You only need to flash it once.
