lr mame2003 - double inputs with IPAC2
-
Is there a way to stop lr-mame2003 reading both the keyboard and the Retropad (which is also the keyboard)? I'm getting double inputs when I try to bind a key because of that. I searched and found a post about setting all the retroarch bindings to "nul", which works but then I can't navigate the Retroarch menu. Is there a cleaner way?

I also had a hard time with this despite following everyone's advice of carefully setting keybindings in retroarch vs mame. My problem was that on a vanilla install, my IPAC2 keybindings were overlapping / conflicting with the MAME's keybindings.
To fix this issue, I ended up flashing my IPAC2 controller with a new bios from Ultimarc that sets up the IPAC2 to be 2 controllers instead of a keyboard emulator. It worked beautifully and made things WAY EASIER with retropie.
Hope that helps!

mame2003-plus has a new input mode specifically for this purpose.
It is activated via a core option which allows the core to process input through the either
mame_keyboardinterface or theretropad-- or both simultaneously as with classic mame2003 (although that is not as useful as you are finding out).
