Fixed the link finally, the only real documentation on there is the CHL file format used in all Black and White games - I could document more like the map and model formats from both games if people are interested, if not it just seems like wasted effort.
I know how to fix the addons, I'll do that when I get some time. As for the auto save, ehh no idea why it isn't working as intended will need more investigation. Any other bugs you can find I'll try and fix them all when I get some free time soon.
To uninstall just run the uninstaller, if that works or doesn't you can then delete the game folder files and then delete the registry keys in the opening post.
I'll look into the patch again when I have some free time (patching assembly is tough!) - but the patch already includes several patches for the graphics, could you take some screenshots if possible?

I believe this Windows Update removes Safedisc drivers, my fan patch mentioned in the OP removes Safedisc protection from the exe and makes it run fine. :)
Hm, well I have the same card as you but I haven't tried Black and White 2 on it yet - I'll probably revisit it in the new year and if I can find these black torches try and patch them.
