This reminds me of the Uzebox [1], a video game console based on an ATMega644, but the RP2040 in this looks far more powerful at a glance. How far could this realistically be pushed?

At least this far. https://www.youtube.com/watch?v=eDVazQVycP4

RP2040 running Doom, includes VGA, Adlib emulation, PCM sound effects, 4 player "LAN". Pretty much the same experience as Doom on a DOS PC.

264 kB of total RAM is the main restriction.
