toptenmaterial Posted June 13, 2012 Share Posted June 13, 2012 I currently have a PSP 1000 running 6.39 pro B firmware. Emulation has been buggy. The smoothest has been GBA, the NES emulator begins adjusting screen position by itself, and the framerate on SNES- for all games- is dreadful. So: What is the solution? Are there optimal emulators for that firmware? And do later versions of the PSP with higher RAM make a real difference? Thanks. Quote Link to comment Share on other sites More sharing options...

goldenegg Posted June 13, 2012 Share Posted June 13, 2012 Emulation on the PSP is not even close to perfect. You're not going to notice any difference between the different PSP models, with one exception. The PSP 2000 and later have more RAM (64MB vs 32MB), which can be helpful with loading large ROMs in MAME. Quote Link to comment Share on other sites More sharing options...

goldenegg Posted June 13, 2012 Share Posted June 13, 2012 Load time isn't affected. With the PSP-1000, MAME will crash loading larger ROMs. The crash is avoided with the PSP-2000 and later. Quote Link to comment Share on other sites More sharing options...

I believe the 3000 and the Go are tougher to hack, but don't hold me to that. For smooth(er) SNES play, you gotta set the emulator to overclock the CPU to 300MHz. Standard is 233 or 266MHz and doesn't cut it. Maybe set a slight frameskip, too. No idea why your NES emu adjusts screen position without you telling it to, sounds like maybe you need a better emulator. Quote Link to comment Share on other sites More sharing options...

I take that back... I can't get MAME4ALL to get past the game settings screen, but until a few weeks ago I hadn't even tried running MAME4ALL in years so I have no idea which firmware I was using when I had it working. These are the emulators I am curently using: PSP2600 Colempsp Jum52 PSPve PSP7800 NesterJ SMSPSP DGEN Lite HandyPSP PicoDrive UO SNES9X REminiscence GPSP Quote Link to comment Share on other sites More sharing options...

PSP-1000 here, running all of these emulators above, smooth as silk. Also - I'm running an older 5.00 GEN-B CFW, and have the system permanently overclocked to 333MHz on all emulators.

toptenmaterial Posted June 19, 2012 Author Share Posted June 19, 2012 ^^ How do I overclock? Quote Link to comment Share on other sites More sharing options...
akator Posted June 19, 2012 Share Posted June 19, 2012 ^^ How do I overclock? Each emulator has settings. Most allow for overclocking, i.e. changing the default speed from 233 MHz to 266 or 333. It is dependent on the emulator and its options. Quote Link to comment Share on other sites More sharing options...
toptenmaterial Posted June 19, 2012 Author Share Posted June 19, 2012 Thanks. Truthfully I haven't played around with the PSP in a few days. Tomorrow I'll mess around with it and post the results. Quote Link to comment Share on other sites More sharing options...
toptenmaterial Posted June 19, 2012 Author Share Posted June 19, 2012 So, I went into the settings of Snes9x and found that the clock speed had been set to 300 MHz. Scrolling has been pretty shitty up to this point. So I set it to 333 MHz, which is the highest its allowed to go I guess. There are a bunch of other settings here, and I am wondering what they mean and what their effect on performance is. Stuff like: smoothing, speed stretch limit, speed limit fps (wondering if I should turn that one off), frameskip, vsync, gamma correction. How are you guys setting these features? Thanks.

toptenmaterial Posted June 19, 2012 Author Share Posted June 19, 2012 I switched the clock speed on nesterj to 333, and there are no scrolling issues. Extremely close to console quality. However the display mode constantly changes (4.3, mirror etc). Quote Link to comment Share on other sites More sharing options...
Lord Helmet Posted June 19, 2012 Share Posted June 19, 2012 I think there are global settings for display mode as well as single game defaults for display mode. You may have different modes set for different games if you're seeing it change back and forth. Dunno if thats it for sure or not but it may be your issue.

toptenmaterial Posted June 19, 2012 Author Share Posted June 19, 2012 ^^ I meant that I'll be playing a game- any game- and after about ten seconds or so the screen starts doing acrobatics. My first thought is to delete and reinstall the nes emulator. SNES still runs like shit playing Super Mario World after adjusting to 333 MHz. However, the NES emulator runs perfectly after setting it to 333 MHz. Sorry about this turning into my personal blog of shame. Quote Link to comment Share on other sites More sharing options...
toptenmaterial Posted June 20, 2012 Author Share Posted June 20, 2012 As an experiment, I installed an early version of nesterj. Same issues. I am thinking that it may be a hardware problem; this PSP looks as though it has seen better days. Quote Link to comment Share on other sites More sharing options...
