I whipped up a fancy way to play Mega Man with some reactive effects from a Playstation 5 controller input. This was for the summer 2025 version of dadageek’s courses.

Here’s a rough draft of the chains I used for this interaction:

Video
Fancy Rom -> RetroArch -> OBS -> OBS Virtual Camera -> Arena -> Effects

Audio
Fancy Rom -> RetroArch -> Blackhole 2Ch -> Ableton

Reactive Effects
Gamepad Controller M4L -> Ableton -> Mac IAC -> Arena
Ableton -> EQ -> M4L live.dial -> OSC -> Arena
