What manner of insanity is that memory map. Start: 0x80000000. End: 0xFFFFFFFF. Size: 4GB....what now? Did I forget how to subtract?

2 gig is the new 4 gig.

Speaking of RISCV emulators, I'm looking for an emulator for ESP32-C3 (the new riscv version of esp32).

How hard would it be to add this to qemu, which already supports sifive boards.

Espressif's QEMU branch has support for the esp32-c3: https://github.com/espressif/qemu

Do you know https://wokwi.com/ ? I have found support for the -C3, and even Rust development. Although it's online, if you are looking for local stuff I don't know if what they use is available, or if it's a secret sauce.

It's secret sauce. They're sort of working on a commercial offline offering, but tbh I think it's a one man band and I wasn't super impressed with the quality level. Which is a shame because the idea is great.
