Lol, look at this source, Does anybody wanna optimize it?

I may try just for the practice. Also, as far as my testing has gone, the cache only needs to be cleared if instructions are being edited, since the game has these stored in the cache (which it never actually updates on it's own due to the game never dynamically relocating executable code), and the cache thus needs to be updated for new instructions to function properly. If the CPU reads the memory instead of running over it as code, it will read the proper value since it grabs the value from the RAM and not the cache.

At least this is what I've gathered about the cache anyways
