Cart can be written to using hw44 commands. Cart appears to be a clone of an AK2.1. Flashing a 2.1 dump onto the cart, leads to a black bottom screen and a black top screen with white loading text.

Not sure if it is ntrboot_flasher or something with the cart, but you have to flash a backup multiple times to completely restore a backup, otherwise you end up with backups with various differences.

The Acekard's flashing code has been super borked for years. I've also had to flash backups multiple times to eventually get the intended data on to the card and I'm using a hw81 version that I'm pretty sure isn't a fake. The official updaters have no issue flashing them. It seems like the Acekard flash code needs to be completely redone in my opinion. It's super unreliable.

Well, that would explain why my card bricked when I restored to remove DSi ntrboot, and needed another reflash to be fixed.

It's very weird, though. Multiple re-flashes in a row sometimes just undoes my changes entirely and reverts the card back to what it was before I tried to write my modified file.

(Also, sometimes, you make just a small change, and yet it writes like 100 chunks)
