Shit I don't remember what was on the file, I just yanked it off my sd card and upped it. I know there is an update skip code, bypass boot warning logo code, and region free game/channel code. I am pretty sure the recovery codes are included in case of a brick, I can check and confirm.

Yeah, so there is skip update, replace warning with back menu, region free channels, remove diagnostic disc check, and auto load disc
Skip update - Games won't prompt you to update to play.....
Region free channels - Pal/U wads will work granted they were put together properly
Replace Warning - The opening is altered.....boots directly to sys menu instead of having to press A at that obnoxious warning screen
Remove diagnostic disc check - Hell if I know
Autoload disc (2 options) - Hold right on the Wii control pad to autoboot your game, comes in handy for reinstalling twilight hack I would assume....may require cIOScorp. I cannot answer this, I have cIOScorp installed so the game will boot regardless.
