So ok.heres where were at....
Mirrored folder placement and config to exactly match working install.
Through daphne laoder,both games accept input via j2k with same profile,aspect ratio,everthing the same,except the roms used.(lair and ace roms).both sets of command line arguments are the same...all works well,all fullscreen etc..happy campers.
J2k joysticks are set up so no matter which joystick daphne sees first?.the inputs will be the same,daphne input settings exact match for both games and work for dragons lair,both inside daphne loader,and in pinballX.
Sadly space ace is getting no input from either joystick,through pinballX,but works fine in daphne loader...
In short,im back to square 1...
Both work as expected in the loader,with j2k,but no input for space ace through pinballX. Dragons lair is Aok.....
If it was a Button conflict with pinballX.i would expect,dragons lair to be not working,but its fine,space ace has same parameters,but no joy...dammmmm...
