Fixed!!!!!
I got it to compile (actually, the ./configure was the tricky part) and added the xsp disable code, and it exits nicely on my 770!

It still uses the home key to exit, but I'll change that next.

I have to fix that because, although it exits ok now, if I use xgngeo to launch it, xgngeo is gone when I exit, but it's still running.

If there's a place to put it, or someone wants a copy, just let me know.

Big thanks to Pipeline for the help!
