Honestly I could see that work with QIIA. All you needed was the triggers for jump/shoot. Even the placement of the right analog stick wouldn’t get in the way since there would be no need to use the A/B/X/Y buttons.
Might even make OutTrigger control better. 🤔
The funny thing about the Dreamcast is it had one analog stick but some of the games could be played with dual. I think Quake 3 was that way. Dreamcast gets all the homebrew too, so it'll help with stuff they just ported over like GTA3
