You have to reach set hard principles for disassembly. I've been experimenting with this for about 6 months now, starting with 4.6 in February where it would do a hacky half ass buggy job of an NES game.

I got a shitty PSX recompiler together in March. Been refining it since. This week along I stood up 5 different psx games and added widescreen to 4 of them and added an in memory injection English translation to another to avoid having to fight the assembly.

Would be curious to learn more from you if you have any other guidance or details.

If you did a write up of that I would be very interested. I assume a lot of others would be as well.
