SalsaDS v0.0.2 (experimental preview)

Experimental preview. SalsaDS is not at full speed in every game yet; there is still optimization and many improvements to do, and you will see graphics and audio glitches. Tested on a real PS3 with HEN; CFW is untested.

What's new in v0.0.2: a much faster CPU

• ARM7 recompiler (JIT). The ARM7 now runs on the same ARM → PowerPC recompiler as the ARM9, with its own code cache.
• Faster ARM9 recompiler. Flags kept in registers, hot and cold code laid out apart, idle and polling loops skipped, and shorter code for common instructions.

Measured on a real PS3 (time to emulate one frame; 16.7 ms is full speed at 60 fps):

Game	v0.0.1	v0.0.2	Frames slower than 60 fps
New Super Mario Bros. (level)	16.7 ms	8.6 ms	37 % → 2 %
Mario Kart DS (race)	20–21 ms	12.2 ms	most → 7 %
Super Mario 64 DS	—	8.4 ms	9 %

Loading screens are roughly twice as fast. Heavy 3D scenes can still drop frames.

Files you can create in /dev_hdd0/salsads/ to go back to the old behavior if a game misbehaves: arm7-nojit (ARM7 on the interpreter), and jit-sin-esperas, jit-sin-ventanas, jit-sin-pistas, jit-banderas-memoria, jit-salidas-copiadas (each turns off one ARM9 improvement).

How to use

1. Install salsads-v0.0.2-preview.pkg (it replaces v0.0.1; it shows up as «SalsaDS»).
2. Copy your own decrypted .nds dumps, with any name, to /dev_hdd0/salsads/.
3. Open SalsaDS: pick a game with the D-pad or left stick (L1/R1 change page), X opens it, O quits SalsaDS.
4. In game, hold SELECT + START for one second to return to the game list.

If something fails, please open an issue with your firmware (HEN or CFW and version) and the file /dev_hdd0/salsads/nucleo.log.

Resumen en español: versión experimental mucho más rápida: el ARM7 también usa el recompilador y el del ARM9 se optimizó. En la PS3 real, NSMB pasa de 16,7 a 8,6 ms por cuadro (casi siempre a 60 fps), Mario Kart DS de 20–21 a 12,2 ms y las pantallas de carga tardan cerca de la mitad. Uso: instala el .pkg, copia tus .nds desencriptados a /dev_hdd0/salsads/, X abre, O sale, SELECT+START un segundo vuelve a la lista.
