hm. guess this topic got dropped pretty quick, anyways i've tested a buncha games, so far only ones that DON"T work are:
Tony hawk Underground
I-Ninja
Deus Ex : Invisible....
all 3 games this was the issue:
all files in root of .iso xferred (default.xbe, and few others..depending on game). and all subdirs were CREATED, however: in many of the subdirs for these games, no files were transferred (eg empty folders).
Note: I've used this tool to xfer about 30 games, and so far these 3 I KNOW not to work.
All I did to test games was to verify they were about the same size as the .iso (I know it'll never be exact..cuz .iso can be smaller or larger depending), and that they booted. It is possible that some of the subdirs in the working games also are empty, but possibly the game still boots as these files might not be needed until later in the game (like textures for certain maps, etc).
If you do fix any of these issues, will you be immediately releasing update? I'll be your faithful tester...;p
