mKo released the first beta of AvatarPatch to be used with homebrew 360s:
It's basically Avatar Patcher combined with organizing tool (like OrganiseLazouzzz).
Features:
-Files can be added with "add file" button or drag/drop.
-"Patch XUID(s)" changes xuid to entered one for every file added to list.
-"Organize" creates new folder structure (content/00...00/..) to programs path where all listed files are copied and appropriately located using mediaIDs.
-Program saves its settings (xuid/size/location) to registry.
To-Do (if i have time and motivation at the same time):
-drag/drop support for folders (now only files)
-ftp (pretty unlikely cause i have no idea what i'm doing)
