MAMEWorld Forums - EmuChat - Assigning multiple buttons to a UI function

Hi guys. Hope you're enjoying your day

I have sort of a complex request/question so please bare with me......

I was wondering if any of you can tell me if it's possible to map multiple gamepad buttons to a MAME UI function?

Now keep it in mind....I don't mean simply mapping for example Joy button 1 + Joy button 2 to "Pause". I realize you can do this already. What I want to achieve, is a way to map Joy button 1, and then Joy Button 2, but set it up so that MAME REQUIRES me to hold Joy Button 1 down while pressing Joy Button 2 in order for the xxx function to activate.

Now the reason I want to do it this way, is because I am using a Neo Geo CD gamepad(USB version) and have already run out of buttons. Everything is already mapped to game specific buttons. So there's no spare unused button left for UI specific things like pause, toggle cheat, etc. I want to assign multiple UI functions that requires me to hold one button down while pressing another, so that it doesn't interfere with my normal gamepad mapping(ie punch, kick, start, select, etc).

Please tell me there's a way to do this, as I really really REALLY want to avoid having to buy xpadder, which then requires recompiling mame, etc.
