I just downgraded my PSP to 1.5 firmware and got 0.4.2me. I fired it up expecting the ROMs to run 100% full speed. They didn't... in fact, they were barely running any faster than when I had the firmware on 2.0. What gives? I read here from a number of people that the ME versions are a lot faster, but I still need frameskip 3 on Tetris Attack to get even close to decent performance.
My video is PSP Accel. + Approx., audio is 11kHz. FF3 runs mostly OK with Frameskip 2, but that's not "full speed" to me. It's really not any faster than it was with the non-ME 0.4.2.
Were my expectations too high? Did it get faster and I'm not really noticing? Did I do something wrong? Was it because I downgraded and it's not "really" 1.5? It says 0.4.2me in the version credits, so I doubt I downloaded the wrong one by accident.

Yeah, I'm running at 333MHz, no vsync, and like I said, the credits in the program say I got the ME version (which I got from a direct link off psp-homebrew.eu, so if I got the wrong one, I imagine a lot of other people did too).

engine: accur software
frameskip: 3
doesn't run full speed but at 55fps with frameskip 3 it's not a big difference

lylebourbon: always get the releases from yoyo's website.

Do you not know psp-homebrew.eu? It's fanjita's database of homebrew, and the download links are direct links to the projects' sites. I *did* download from yoyo's site. Anyway, I've downloaded 0.3me, 0.4.2 standard, and redownloaded 0.4.2me (all from yoyofr92.free.fr/psp/files/), and I'm going to try them all today. So we'll see if it was a bad download or something. |

Ok, so from my tests, with 0 frameskip, 0.4.2me gets a 12fps boost in Tetris Attack's game select menu (from 47 to 59) using PSP Accel. + Approx. However, it still only runs at 20fps in ME in the actual game. Same settings on both: 333MHz, no vsync, Zoom 4:3, smoothing, Frameskip 0, 44kHz sound, speedhacks on, everything else in the Hack/Debug off.
So there is a speed boost, I guess it just wasn't as big as I was expecting from the way everyone was talking about it.

Tetris Attack is not a good game to test, that game has ran poorly in every SNES emu release. Its in the league of Star Fox and Mario RPG  try something like Soul Blazer, Super Castlevania, Earthbound, Dragon Quest, Super Metroid etc.. those games have a huge performance boost as with many other games. also FF3 with fs 2 is fine to me, you should probably leave it on auto. FF3 runs full speed out of battles but needs fs in battles. |

Crap, that's really disappointing. Having easy access to handheld Tetris Attack was one of my main reasons for emulating in the first place. Still, slow Tetris Attack is better than no Tetris Attack. At least other games run faster. I'll have to test with SM All Stars or Kart to see how much of a boost it is.
Still, it's a d**n fine emulator. Keep up the good work!

you should read into WHY certain games are slow, and remain slow, and test using games that can actually be properly emulated  |

Another thing you can do for speed improvements, in the emulator menu under Misc go into the Hack/debug menu and turn on some of the options there. The downside to this is it usually causes some graphical errors, but usually they're minor enough that they don't affect the game. (Try turning them on one at a time to see which ones cause graphical glitches)

It's not in the stickied list of special chipset games -- I figured it's just a puzzle game, and so isn't as complicated as, say, Star Fox. Do you have a link where I can start reading about it? |

Lyle, you're not the only one wondering...
I have a 1.5 PSP and currently run 0.2c. I've tried one of the 0.3x ME's and both 0.42's. The games I'm using to compare the SNES9x versions are these: Killer Instint, FF3us, Super Mario All-Stars and Chrono Trigger.
I did my best to make sure all the relevant settings matched where possible, and tried various combinations. I STILL get better FPS out of 0.2c (I can play most games with a skip of 1). I really want to get a version of SNES9x with Netplay. Is there something I'm missing? I got all my DLs from pspupdates' links if it matters.
All that said, SNES9x is one of my favorite pieces of software on the PSP and I'll keep using it regardless. Thanks Yoyofr!

Hi !!!
Sorry, i have been busy for a while...
The 0.2C have all the workload on the CPU, the structure then is simpler for all the audio emulation part.
When sound is set to "No Emulation", the code runs a different loop that skip completly the sound emulation. I even believe that the sound thread (Sending the sample to the audio chip) is also not activated.
Because of this difference, 0.42ME even with no sound setting is slower than 0.2C
See you.
