#262 How to bind Save State and Load State to controller buttons?

[NS.]

Windows 7 SP2 all updates. Xbox 360 for Windows wired controller. VBA is working great.

I would like to map/bind the L1 and R1 controller buttons to VBA Save Slot 1 and Load Slot 1 commands but I can find no way to do this. Can you help me?

TL;DR: Using JoyToCon to bind L1/R1 to Save/Load State doesn't work.
As a workaround I tried using JoyToCon to map those controller buttons to F1 and Shift+F1 but that didn't work. It's like VBA is just completely ignoring those buttons, but when I press L1 outside of VBA, I get Help (F1) for whatever program has focus, so I know it's actually sending the keystroke, but VBA isn't doing anything about it. I can still press F1 and Shift+F1 on the keyboard, but that's impossible to do when you're actually in the middle of playing the game, especially with a controller. It's just not possible to stop in the middle of action, let go of the controller, then find and press the key to save. Also, JoyToCon does work to map R1/L1 to F5 (Save State) and F7 (Load State) for Project64.
