Okay, after borking things up with the appdb entry, here is how I get the game to mostly work.
1)Installed via Steam
2)I found no difference with the advice of adding in the xinput1_3.dll at this point. The mouse is janky and the l/r mouse movement gets "stuck" and I need to do a mouse jiggle to make it work again.
3)The maps crash out if the music directory exists as it looks for it. I renamed my folder to simplify things out a bit.

Any tips for the mouse issues would be great :D
Thanks,
