I got almost all of my wishes granted with RP2350

RP2040 had Doom ported to it. https://kilograham.github.io/rp2040-doom/

RP2350 looks very much like it could potentially run Quake. Heck, some of the changes almost feel like they're designed for this purpose.

FPU, two cores at 150 MHz, overclockable beyond 300 MHz and it supports up to 16 MB of PSRAM with hardware R/W paging support.

While outputting DVI! I wouldn't be surprised.

Mouser have 64 megabyte PSRAMs.

I really want a Mac System 7 grade operating system for this chip...
