Options for multiple bindings for the same function across ALL emulators

[syntax_X]

Ive got my machine set up with some PS1, Arcade and N64 classics, with usb controllers for each.

Mames default controllers are the arcade cp, and I'm finding sometimes when I play fighters and such others want to use a PS2 controller to vs me.

When playing Sega I don't want to use the joystick to play sonic, id rather the PS2 controller, but then id want to use the arcade cp for fighters and shmups.

I'm currently setting up joy2key to sync all the joysticks together so I can pick up any one of them and play without changing any settings and such, but is there another option I'm overlooking??
I wish every emulator allowed multiple commands for each input like MAME does,..  then I could assign all 3(6) controllers independently

Just found this https://autohotkey.com/boards/viewtopic.php?t=12249
Universal Controller Remapper.

Looks like this can chop and change my joysticks to 2 virtual pads (16 is the limit)
Its a slow interface and will take forever but it avoids having to use keyboard keys and joy2key for bindings which across 10 or so emulators always has issues.
