Can you play Daggerfall on the Anbernic RG35XXSP?

I’ve got muOS installed on my SD card.  I’ve managed to get the game to run in the DOSBOX emulator but I cannot figure out how to map the controls.  Basically a question of running a KBAM scheme on a PS1 controller.  I want to know if it’s actually possible.  I’ve tried using various configs or messing around with the in game controls and the emulator controls in the muOS settings (like mapping L3 to L2 so I could bring up the keyboard in the command console), but no major breakthroughs.  Maybe I missed something.

I thought about maybe picking up a CRKD controller with joysticks since the SP has Bluetooth but that’d be kind of insane getting a separate controller for that small of a screen.  

Another option, if mapping the controls is actually possible, is to figure out which controls aren’t necessary, ergo I could navigate to them as needed via other menu options or such. 

Does anyone have any suggestions?  

& maybe if we pull this off we can try running Undercroft by formerly RakeInGrass on the system next!
