Multiple X360 Pads as GC pads

[CacoFFF]

nJoy sometimes failed in some revisions to detect axes in the config dialog but always worked ingame, post a pic of P1 config using nJoy.
And the nJoy.ini as well.

It shouldn't be so different to configure as any Dual analog game pad.
Since you have 4 xbox 360 controllers, manually setting player 1 and then copying those settings to p2,p3,p4 should work perfectly.
nJoy 0.3 and 0.4 save the config differently, so remember to tell which version you use.

EDIT: Say, the nJoy drop-down list only shows one of the wireless pads?
Does the control panel show 1 master pad (probably the wireless receiver) or 4 individual ones?
