#5I'm still not 100% sure what exactly this is, even after reading the description thrice. Is it basically a RISC-V core in a system with standard x86 PC peripherals, i.e. a very odd but theoretically possible configuration to emulate, in the same way that QEMU (of the same author) lets you attach e.g. a classic VGA controller to an ARM core?

I think it’s both a a RISCV emulator and an x86 emulator. I think it’s both, presumably reusing some pieces allowing systems to be emulated like you say with weird configurations.

#7The B extension never gets any love.
The RISC-V crowd hates bitwise anything.

B extension was ratified in 2021, near the end.
It is considerably newer than every extension this emulator implements, and thus reasonable it'd have these and not B.

#9To the risc-v folks: I am looking for a mini-board with a 64bits RISC-V core, USB-C (power+data), many(~30) available GPIOs, easy to flash or boot from a memory card. That for a keyboard firmware directly written in 64bits risc-v assembly.
The BL808 is actually a 32bits risc-v as a main core with a 64bits risc-v core on the side (convoluted hardware programming from the 64bits risc-v core).
The K210 does not seem to have a USB controller (only a UARTUSB dongle).
Then I am lurking on some mango boards, with a D1, the D1 being completely overkill.
Anything else?

The soon to be released VisionFive 2 board seems like a good match https://www.starfivetech.com/en/site/boards
