Emulador CEN64 (Cycle accuracy), por MarathonMan

doblete escribió:Que buena noticia saber que hay gente que quiere emular la consola al 100 %, si la gente del proyect 64 lo hiciera Open Source, convinando los dos proyectos ya se tendria gran parte del trabajo hecho , espero que el proyecto se convierta en un nuevo dolphin , en fin esto promete mucho .

-Wrote the scalar unit, CP0, etc. of the new RSP core this weekend. Completely redesigned, using the same optimization techniques that proved advantageous to the VR4300. Due to the RSP's smaller instruction set on the scalar side, there may be an even greater increase in performance over what the VR4300 saw. I have an additional technique that I haven't tried that I may be able to apply to the SSE vector operations, too. Even without that, the new core is shaping up to pummel both the performance and compatibility of the old core.

-Did a handful of micro-optimizations to the VR4300 core and main loop of CEN64, which resulted in a >5% improvement on my two test machines (different architectures, speeds, etc.). [*]CEN64 now simulates MCI (multi-cycle instruction) interlocks properly. Heavy FPU-based ROMs especially benefited in both accuracy and performance after I began simulating the interlock.

-Merged angrylion's newest batch of RDP fixes and optimizations, which also resulted in a performance boost. Unfortunately, as shown by cen64-backport, this seems to have broken some ROMs, such as DK64. Others, like Zelda: OoT run noticeably faster.

Tengo entendido que el requisito de los 64 bits es una cuestión estructural de CEN64.
