Well, in theory the graphics that make up the cursors should be in a folder in the game directory somewhere. I've seen this with some games but not others; they may be buried inside a big library file. Scan through the game folder and see if the icon pictures are there.
My advice would be to post in the game's forums and get the developers to help you. Even if you could extract the icon files, getting them to work in Windows is a whole other ballgame. But maybe you already know how to do that bit.
Don't talk to the developers what ever you do, you will just give them ideas and we will have to pay £3.99 for the cursor pack just like you have to pay the same price for wallpapers for the Xbox360 *yuck*
On another note... 800 Microsoft points to change your god damn name... I set this name up on the original Xbox they didn't charge me 6 god damn quid to change my name back then, what a bunch of corporate bull
Ya I just posted on Soul Reavers forum about extracting this icon. Hopefully they'll tell me which file its in. I already found the software to extract any textures, but its just finding the damn thing, lol. Thx though.
As far as paying for extras and stuff, I'm not too concerned. You can find anything digital on Torrent sites now. I'm sure you can find just about any Wallpaper for teh Xbox on a Torrent site. I'm sure you could find what ever pics you like of Soul Reaver on the net and just find something to convert them and transfer them onto your Xbox.
