edit: Now I'm not sure what is causing the crashing. 0.71 still seems to crash on my system even w/o the gamepad. (though I haven't tried rebooting and unplugging the wireless recv) 0.70 was really stable on my system, but I can barely get 0.71 to run!
edit2: I believe it may be the process "XBOXSTAT.EXE" that runs even after your controller is disconnected that may be causing the crashing.
I am not the original poster but I am having this problem with a wireless 360 pad (w/ wireless receiver) and v0.71 of DOSBOX which was a mandatory Steam upgrade for the id Software collection.
However, 0.70 seemed to work fine w/ the 360 pad... Also, can you forward the upcoming version to Valve so it works on the id Software collection? Wolfenstein is not as fun without a gamepad. 😀 Thanks!
