been thinking about fantasy computers and virtual machines

i am not as proficient in C as i am in lisp, so i find the quick uxn emulator code on the wiki difficult to understand

if i was gonna write a lil virtual machine, i would adapt this:

https://github.com/kingcons/cl-6502

this would give me all the tools i needed to do it in common lisp

but i wonder--why would i do this? what kind of virtual machine would i write? i am not sure.
