Xam App

Recording more unknown app messages for future reference.

    Xam message 2B001 is called in Toy Story Mania!

    Xmp messages 7002F and 70044 are called on the start of all dashboard versions before the Kinect update. When 70044 is set to return X_E_FAIL you can access the xbox music player but when it succeeds the emulator locks up and you are forced to close it manually (no crash). The music player can't be access at all past version 5787 and instead goes back to the previous screen as if it is closing itself down. 7002B (NXE and Kinect) and 70053 (Blades) are called when trying to access the music, picture, and video libraries.

    Messenger is only called when using netplay with dashboard versions 5759 to 5787. After that an "xbox live is currently unavailable" messaged is displayed on 3 of the tabs (marketplace, xbox live, and games) blocking any internet related messages from appearing on versions 6683 to 6717.

    Xlivebase message 5008C is called on the start of dashboard versions 1888 to 2858 and 50094 is called instead from versions 4532 to 4552. LogonGetHR is called on the startup of dashboard (netplay version)

    XGI message B0036 is called after clicking on xbox live in the arcade library (v5759 to 5787) or from the game library (v6683 to v6717). B0021 is sent in the games Fatal Fury Special and Beijing 2008. B003D is used by UFC 2009 (netplay build).
