I downloaded this app the other day, loaded it on my XBOX and now I can play the
Psychonauts USA game no sweat... works for me...
will it work for you ... who knows

I have XBOX with Xecuter and EvolutionX.
When I tried to play Psychonauts USA, it just dropped back down to dashboard.
Tried changeing NTSC/PAL video mode in settings, same thing happened.

Loaded this little app, set to NTSC, rebooted and Psychonauts USA loads fine.

I put the app in eapps and edited evox.ini, added this line so it shows as last item on menu.
Item "NTSC-PAL","e:appsNTSC-PALdefault.xbe"

>>>>>>>>>>>>>>>>>
menu section from evox.ini with NTSC-PAL added shown below...
..I also have added XBOX.Media.Center as the first item on my dashboard menu, so when hooking up to pc (no wifi) i can load MediaCentre and ergo ftp without having to hook up a tv also.
