After updating the AK2i Bootloader (firmware) I no longer see the Acekard icon, why?
The DSi security works by verifying that the game about to launch is an actual game by the icon being loaded. For the Acekard to bypass this first check it must present itself as a real game. The icons you can expect to see are Danny Phantom - Urban Jungle (DSi v1.4.0), Alex Rider: Stormbreaker (DSi v1.4.1), Atama de Do! Koten Kotenko DORASU (3DS 1.0.0-0), Chessmaster - The Art of Learning (DSi v1.4.2 & 3DS 2.0.0-2), and Hello Kitty no Panda Sport Stadium DORASU (DSi v1.4.3 & 3DS 2.1.0-3/2.1.0-4).
I want to change the AK2i icon, how can I do this?
The original AK2i (Acekard.com) icon is hardcoded into the original firmware and can not be changed. More recently, the icons change with firmware updates, these icons are actually partial game data designed to exploit the DSi/3DS checks. These icons can not be altered and attempting to do so would render the card unusable and unbootable.

QUOTEAs the icon is a key feature to circumventing the first check, the icons which change with each bootloader update can not be altered and attempting to do so would render the card unusable and unbootable.
