This could be easily done. The emulator core supports memory mapped IO, but uvm32 only uses this to map an extra block of RAM from the host (for a framebuffer, or a separare memory…

libriscv looks amazing but its's much larger. It says "Less than 40kB total memory usage". My first version (unpublished) of uvm32 was called uvm80 and emulated a Zilog Z80 CPU. My…

Continuing from part1 where we ported an RV32 emulator from C to Zig ( https://www.ringtailsoftware.co.uk/zig-rv32/ ), we can now use Zig to cross-compile a binary to run in it
