Eric,

congratulations on your project!

An interesting direction to take this would be to make it compatible
with the processor simulator interface in Cog. In the case of ARM and
x86 this interface calls external programs but in the case of MIPS it is
a simulator written in Squeak. You can find this in the VMMaker package.
Something like this would be the first step in a port of OpenSmalltalk
VM to RISC-V.
