SaveGame Manager GX by dj_skual allows you to extract/install SaveGames and Miis from/to your Wii; data.bin files not supported. It allows savegames to be copied from the Wii to an SD card, including savegames that cannot normally be copied from the system menu. It is a modification of the Savegame Manager from Waninkoko. Unlike Savegame Manager, Savegame Manager GX has a wii-like user interface.

Changes:

Added an automatic resource list generation script which is executed when files are added/removed (Thanks Dimok)
Added an own class for the HomebrewPrompt
Added booting with arguments from meta.xml for homebrews
Added an argument receiver from meta.xml to the app: “-ios=xxx”. The ios is the boot IOS on startup
Fixed Homebrew Browser duplicate buttons for apps with more than one dol in the app folder
Fixed lot of problems with USB HDD (need feedback)
Fixed the “GoogleCode” AutoUpdate problem (one more time…)
