I'm looking for a PSX emulator (or a 3D plugin for it, or just a method) that would allow me to freely look around a 3D scene when a game is playing.
I know one emulator that allow to do that, Dolphin emulator (Wii) : you just need to enable an option in settings and then press keys to move around. sometimes the game just crashes but some games allow to do it and this is pretty nice cause you can easily see how some stuff are implemented.
In the case of Dolphin, I guess it works by multiplying projection matrix just before rendering the whole stuff. For PSX, I could maybe locate where game buffer swap is done and multiply matrices by myself but it seems a lot of pain, my psx hacking skills are pretty limited, and it will be specific to one game. Any advice ?
