    Hi!! I got PSP working 100% perfect , both PPSSPP and lr-PPSSPP , perfect speed on video and sound but once in a while, sometimes every 2 minutes, sometimes 5, it freezes completely and the sd card light is constant yellow not blinking, for about 10 to 20 seconds. I guess is transfering something.

    Tried different configs for memory: 512 to 128 gpu in case it was trying to make some heavy swap but nothing changes. Tried with a couple of 2D’s: Metal Slug XX , Midway Arcade Classics, SF Alpha 2 Max and Puzzle Bobble. Same deal.

    My sd card is not the best, 32gb class 4, but it’s quite funny behaviour, dreamcast games for instance don’t show this issues. This very same card worked flawlessly on my cellphone with PPSSPP for android.

    I’m using a RPI2 overcloked @ 1066mhz 533 mhz L2 and 483 mhz sdram . I believe it doesn’t have to do with processing speed, just an I/O issue.

    Any ideas? Can someone confirm similar setup with PPSSPP having not this issue? It’s a shame it works so nice but has this i/o thing wich makes it unplayable.

    Cheerz, thanks in advance! Great job with Retropie i love it !!!

    Can you post your lr-ppsspp and ppsspp settings so that we can try to reproduce what you’re seeing?

    Yes – please do this urgently so others can have a go :D

    IO issues are probably caused by your SD card class (Class 10 is recommended). You might also have a dodgy power supply.

    I’m pretty much sure it’s the sd speed wich causes the I/O issues, still i’d like somebody to confirm he/she has it working okay with a faster card. I’d love to have this system working properly, it seems to work very well at least with the 2D games. Metal Slug 6 and Metal Slug XX …

    There are some options you can try in regards to io – check in PPSSPP settings. Did you try adjusting any of them ?

    Tried changing many settings , i think the most I/O related ones, like CacheFullIsoInRam and SeparateIOThread, FastMemoryAccess and FuncReplacements.

    Now that i see it, i didn’t change IOTimingMethod , i’m gonna tune that one and see what happens.

    Anybody tried it? ppsspp or lr-ppsspp ?
    Any experiences to share? Cheerz.

    Hey OP!

    I finally got LR-PPSSPP compiled and running. No IO issues (I’m using a class 10 MicroSD, Pi is not overclocked).

    I haven’t applied your config settings yet.

    My experience thus far has been:
    -Pure 2D games work great
    -Fancy 3D titles (Ratchet and Clank, Dissidia) crash after the start screen. Tekken 6 runs but is monstrously slow.
    -Hit and miss for other 3D titles. Legend of Heroes is 100%, while GTA Chinatown Wars is a bit laggy. LittleBigPlanet is perfect except for some busy areas where it slows down sightly.
    -Some titles are missing some 2D elements (such as menu text) but otherwise work great (MGS Peace Walker, Monster Hunter Freedom Unite).
    -The emulator can’t display the PSP keyboard.

    This is very exciting though – I’ve tested about 40 popular titles and I’d say about 50% work perfectly. That’s a really good start, especially considering I haven’t gotten into the settings too deeply.

    Great New!!! Thanks for sharing! So i guess it’s a matter of sd card speed/quality , i should get a faster one if a want better psp support. Thanks for testing buddy!!

    I did notice one thing – you have the following setting:
    CacheFullIsoInRam = True

    This would work fine for small ROMs, but most PSP ROMs are well over 1GB in size which would exceed the Pi’s max memory. Could be what’s causing your IO issues.

    Excellent!,thanks for the info!!
    My pi2 is even more overclocked than that but the thing here is something related to I/O operations.

    I’ll try tonight with those settings and let you know. I friend lend me an 8gb class 10 sd card, will try with that too and finally i have a spare external usb hardrive, will see how that works.

    Hi! i tried a couple of different settings and still freezes for a couple of seconds here and there.

    Then i tried something different: used an usb flashdrive with a 2gb sd card and pointed the roms dir en es_systems.cfgt to the mounted sd.

    Emulation Station recognized it and listed the roms correctly. Run some roms and it freezes but the light that blinks it’s still the green one that’s beside the red power led on the pi. I don’t know , does that light blinks when there’s *any* I/O activity or just the “main” sd card? If it’s just the sd-card then the emulator is using some kind of caching/swapping system i guess, otherwise it doesn’t make any sense.

    What’s your cpu/gpu mem sharing config?

    256mb.

    Only other thing I can think of is that your OC may be too high. Either that or the emulator is still a bit buggy. Are you using LR-PPSSPP or the standalone one? I’m using LR-PPSSPP.

    repuken2

    Tried both, the standalone seems to be slightly better. Tried today with an 8gb sandisk ultra class 10. I works way bettter, still freezes once in a while but less frequently, and sometimes yellow light it’s not blinking so it’s not entirely an I/O factor it seems but pi’s processing power. I guess this emu needs more work but impressive none the less. If i had more time i’ll dig into it to see if i can improve it.

    I also have a class 10 sd card with the same issue (pauses in game-play with otherwise smooth emulation) If anyone has any new information it would help tremendously. Thanks!

    Those talking about the freezing etc – have you all tried changing the “IO Timing method” in the system settings (with standalone PPSSPP) ? By default it is set to “Fast” which it says can lag on slow storage.

    Thanks for the help Buzz! It doesn’t seem like it did much if any good. It seems like lr-ppsspp is doing the same thing so It might be memory card related? I have a 64GB Lexar class 10

    repuken2
    Participant
    Post count: 12

    Hi, the freezing thing was sd card related. I tried IO Timing method from 1 to 3 making no difference at all. I’m using a 32gb sd hc1 class 10 now and it works perfect, once in a while it would freeze for 0,5 seconds, almost nothing. It happens on my cellphone too.

    Funny thing is i have the isos on the old 32 gb sd class 4 via pendrive/usb adapter, so it’s related to how the emulator manages memory, specifically swap or some sort of cache the must be read from main sd. Also the size of the iso doesn’t affect performance

    Hope it clarifies things for everybody.

    Also having this problem myself . I’m using the 3.5 image and a class 10 integral brand sd card and get really good results but as described above every few minutes I get a pause in emulation for a few seconds. Did anyone get to the bottom of this or is it an ongoing problem ?

    Post count: 12

    Hi cooky069, what i can tell from my own experience, and having tried a couple of differnt brands + speeds, this has to do with the card speed, because of the swap handling the emulator does, wich seems to be pretty heavy. I don’t know that brand Integral, maybe the speed advertised doesn’t match class 10 ? It’s the only thing i can think of.

    Thanks for the info guys . When I’ve got time I’m going to try zerojay’s suggestion and set up a hdd. Iv had chance to check the read write speed of the integral card and can confirm it is pitifully slow! It barely qualifies as a class ten. I set up a new SanDisk card and there is a noticeable difference , not perfect but definitely better. I also speed tested the SanDisk and it doubles what the integral is capable of

    Lr-PPSSPP here. Running off HD, distro updated, and Castlevania runs pretty much as it should. A slight slight slight hick up here and there, but you kind have to be looking for it.

    This is an improvement since when I was on the old Wheezy distro release.

    EDIT: I did not edit my config.

    I have a really aggressive overclock on my pi that gets most PSP games running nearly perfectly. I do have a cheap sd card though, I do see some sub-second pauses in quite a few games, but they’re still very much playable. I’ve tested an absolute ton of titles and have found over 100 games that work well. My psp games are on an HDD.

    Here’s what I’m using, these are guaranteed to void your warranty, don’t blame me if you blow up your pi with these:

    gpu_mem_256=128
    gpu_mem_512=256
    gpu_mem_1024=384
    gpu_mem=384
    arm_freq=1100
    core_freq=550
    sdram_freq=500
    over_voltage=4
    
    force_turbo=1
    avoid_pwm_pll=1
    v3d_freq=450

    My pi has a heatsink kit like this. I also have a massive case fan. (140mm I think) Don’t try these without great cooling.

    How long have you been running your Pi with these settings?
    Also what are some of the more advanced PSP games you are able to run and well?

    Lastly, can you take some photos of your Pi with case? :)

    THanks!

    The most advanced PSP games I can run and run well are the Ys series (7 is a little choppy), and Castlevania.

    When I was testing psp games, I added all of the games that worked (and didn’t) to the compatibility sheet on the wiki if they weren’t already there. I think I missed a couple, because I have a few more working games than I counted on the sheet, but it’s pretty close.

    I’ve been using those overclock settings for just about a month. I started using them specifically for PPSSPP. No issues yet.

    Here’s the hardware that I’m working with:
    my pi 2

    That case is just a tupperware container I found at an art supply store. To keep from having issues with static from the tupperware case, all of the electronics are lined with thick paper between the PCB and the tupperware. You can see part of the paper sticking out from under the PI. Everything is secured in place. While my overclock settings are recent, this case setup is not.

    I removed the back of the power strip so that I could screw it down also. I was a little worried about that at first because risk of shocking the shit out of myself, but again I lined the back with thick paper to keep anything from grounding out. No issues yet. :)

    and the outside

    the two buttons on the case are a hard reset/power on switch using the reset pins. The other resets or shuts down the pi depending on how long it’s held down. I highly recommend the second one, as it’s saved me from cutting the power on my pi numerous times.

    That list does not compare to my experiences, such as the MegaMan remake.
    The list says it is fine, but when I ran it, it ran slow and choppy. The 2nd time I tried to load it, it booted me back to emulation station.

    There are others on that list that don’t run as well as page claims.

    I have some “minis” I could ad to that list though that do work.

    You probably aren’t overclocking or aren’t using the same settings. I can confirm that Megaman Powered Up runs super smoothly here, for instance.
