Interesting timing - been looking for exactly this for embedded firmware testing. Most alternatives are either too heavy (full emulation) or too fragile (custom interpreters).

Have you considered adding support for memory-mapped IO simulation? That would make it useful for testing IoT/microcontroller drivers without the actual hardware.

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 heap). You can trap the writes here: https://github.com/ringtailsoftware/uvm32/blob/main/uvm32/uv... and the reads here https://github.com/ringtailsoftware/uvm32/blob/main/uvm32/uv...
