📄 Description

Overview

This is a cut-down version of #23, meant to provide very basic, simple virtualization at the cost of perfomance.

Goals

Simple implementation
Virtualize all registers
No register allocation
Support most (all?) ps4 instructions/regs, though just passthrough
Basic, per thread code cache
No SMC support
No instruction rewriting for most operations

Todo

Get basic hack-and-slash demo working
Decide on a testing stategy
Rework to less horrific code
Support multiple threads, TCB overflows, and other corner cases gracefully
