I'm curious what the games look like, does it retain the PS1 "wobble" or would it look more clean with the GameCube rendering?
i may just be talking out of my ass but i recall one of the dolphin devlogs saying something about the gamecube not having an fpu either. it got around wobblies by being 64-bit or something. if that's the case, going 32-bit only would reintroduce them.
Duckstation has a way of "removing" the wobble. I don't remember what technique they use though, it's been awhile since I looked at it.
It makes the games look way better too. Just play through metal gear solid 1 and was impressed with it.
I'm not sure, but the reasons for being "wobbly" are pretty interesting: https://retrocomputing.stackexchange.com/questions/5019/why-do-3d-models-on-the-playstation-1-wobble-so-much
If I was deigning an emulator, I'd try to match the behavior of the original system as closely as possible, since people designing a program for that system might have depended on any behavior they observed (intentionally or unintentionally), so I'd keep the "wobble" (or provide a way to disable it, but keep it enabled by default).
There is no ability to benefit from poor texture mapping. The wobbling textures are essentially random. There is a finite number of PS1 games, and no game has ever "depended" on this behavior. Your argument is nonsense. Current emulators have the ability to fix textures.
