hey Yoyofr do u think is possible to improve ljp's speed?
im playing snes roms on my TE using lightspeed at 192 mhz with the sound disabled and it work well and fast, but my batery life go quickly, long time ago when i had a 486 PC at 100 mhz i played SNES wihout problems with the sound disabled, so is it possible to run snes on palm well with 100 mhz and without sound like i played on my old 486? maybe with a specific version of the ljp for slow devices?

Right now yoyo is trying to get everything to just WORK. I think when everone can just download the emulator and not have to worry about UDMH and stuff like that, THEN speed optimizations will happen. Not to be a grouch  |

Speed improvement in snes module will be hard since it's already heavily optimised compared to the original snes9x. If you think about the "old times"  where zsnes could run a snes rom on a simple 486dx100, then remember zsnes was written in 100% assembly where snes9x is a portable emulator. In the process of adapting it to the gp32 & later zodiac/palmos, an full arm assembly cpu emulation core for the snes processor was written  , gfx emulation was rewritten, sound sample decoding was rewritten in assembly... There are still area to optimize (sound cpu emulation, sound mixer, dsp1, c4, superfx), but it will be hard to have a major gain without restarting from scratch (and I've not enough free time to do this).  |

Yoyo, have you considered turning LJP into a commercial product? With enough revenue to fund programmers rewriting the code from scratch (you or other coders), SNES could be optimized to run at 100% speed for most roms I believe. Generally I am not a fan of commercial emulator software, however, I have had very good experience with magicengine, a commercial turbografx-16 emulator for PC that runs both roms and CDs. See also www.magicengine.com for details on that emulator and positive feedback from users. |

Open source projects are better anyway because he has multiple people working on it at the same time. |
