TIC 80 mapping A/B/X/Y buttons

Has anyone been able to map the A/B/X/Y buttons in TIC 80? The buttons are recognized in other games like Cave Story. I also added SDL mappings in my .profile file. Still, the ABXY buttons have no response in TIC 80. I’ve remapped them to some keyboard keys for now, but I’d really love getting full gamepad support on the uConsole in TIC 80. I want the uConsole to be my fantasy console development device.

Edit: Tried compiling the latest commit in the project repo from source. ABXY still aren’t recognized.
