Hello all! I have been fiddling with this wonderful emulator for a while, and decided to share what I have learned from using it. Also, I wanted to thank the developers for this wonderful emulator, which really gave me nostalgia as I sold my PSP a couple of years ago.

Just for clarification, I'm not trying to take away from the great stickies in this forum. If you're new to PPSSPP, go ahead and read those to get yourself introduced to the emulator. However, I would like to go a bit in-depth to some options of this emulator and tell you what I have discovered.

Just for reference, here are my computer specifications:

OS: Windows 7 Home Premium 64-bit
CPU: AMD Athlon II P320 Dual-Core Processor 2.10 GHz (Laptop)
Graphics Card: ATI Mobility Radeon 4500 Series
Memory: 4GB 1333 MHz DDR2 RAM
HD: 7200RPM 320GB

As you can see, I haven't got a killer gaming rig. I can still run my favorite games just fine. Your mileage may wary, as different games require different amounts of computing power.

But let's begin optimizing our gameplay experience.

Foreword: I'm not a "professional" at computer-related stuff. I simply have a passion for gaming and I want the most out of my games. That's why I have gone to lengths in trying to maximize my gaming experience on this emulator, as I really loved some PSP games.

The recommendations and suggestions listed here are derived from my own experience only. I haven't gone through every game to test my theories, so you may see different results. However, I do recommend reading these hints and trying them out - perhaps they can help you.

1. Fixing choppy sound
The most recurring issue I have had with this emulator is crackly sound. To my understanding, getting the sound to work has been quite a challenge for the developers, and the current implementation still needs some fine-tuning. Regardless, I'm impressed by how well the emulator supports most games.

The problem I have had with sound, is that it usually works, but not perfectly. In Patapon games and Disgaea 2, for example - the sound would work but I could hear a slight but continous crackle when the BGM was playing.

In Disgaea 2, opening certain menus within the game would cause the background music to distort and crackle like a jackhammer.

This can fixed quite easily. In your PPSSPP settings, navigate to SYSTEM, and set your CPU Speed to values between 222-1000 MHz. You should not have it set to 0 (auto), as the emulator doesn't quite know whats good for you.

I found out, that for Patapon, a setting of 222 MHz was sufficient for my PC, but in Disgaea 2 - the problems remained. When I cranked the speed to 800 MHz, I got a noticeable result and the game no longer freaked out when opening those certain menus.

Just for safety, I maxed out the CPU Speed at 1000 MHz. I would recommend this setting in case your computer and game can handle it.

YOU HAVE TO QUIT THE GAME YOU'RE EMULATING AND RESTART IN ORDER FOR CPU SPEED CHANGES TO TAKE EFFECT! DO NOT BE FOOLED BY IT BEING AVAILABLE FOR TWEAKING IN-GAME!

The experimental atomic audio locks feature has only made my sound problems go from bad to worse, so at this point I wouldn't recommend enabling it.

The same goes for Sound speed hack and Low latency audio. However, if you're playing a musically intensive game like Patapon, for example, turning on low latency audio is a must. If your PC can handle it, then go for it, keeping in mind the other things mentioned here.

However, the important thing to note here, is that CPU Speed can marginally affect your gameplay experience, and you should definitely raise the speed if you're having similar problems.

2. Random crashes on ATI cards
There's apparently a compatibility issue with PPSSPP and newer AMD drivers for legacy video cards. Since I have a old video card, I have been suffering from these issues. However, this issue has been noted and a workaround does exist - a older video card driver.

For more details, check the sticky thread on top of this forum. I cannot stress what a life saver that thread was for me, so I'm throwing a mention about it here aswell. Check it out if you have a older ATI video card!

After downgrading my graphics driver to 11.11a, I haven't had a single crash.

Of course the emulator may still crash for other reasons, and if you are using a newer graphics card or a NVIDIA card, this thing won't affect you.

3. Optimizing demanding games
Some games are packed with action and improved PSP graphics, so they will demand a higher amount of resources.

In cases where a game is lagging, and you wan't to squeeze out maximum performance without losing much image quality, pay attention to these options.

Change Rendering Mode to Non-buffered Rendering
This is a setting which gives out a huge performance boost. It might not work with all games, as some require buffered rendering to be on. Some games also have very specific requirements as to which rendering mode to use. Search the forums for these exceptions, I won't go into them. Note however, that the "Read Framebuffers to Memory (CPU)" and "Read Framebufers to Memory (GPU)" options are way more demanding than the simple Buffered Rendering. And personally, I haven't found a visual difference between the three in my games.

Rendering resolution and upscaling textures above 2x
I would never recommend rendering or upscaling above 2x, simply because the overall visual improvement is so marginal that it doesn't warrant the performance cost. I would leave the rendering resolution at 2x, same for the upscale.

If the game cannot warrant both of these options, then turning off Upscaled textures might be enough to resolve your FPS issues. I would prioritize turning it off first, as it causes a huge performance hit.

For the Upscale type, I have left it at the default xBRZ. It seems to offer the best quality/performance ratio.

If you see graphical glitches, you should also enable Deposterize and see if it resolves them. I personally keep Deposterize always on when I have the Upscale enabled. In my tests it doesn't seem to cause a huge performance hit. If your PC and game can warrant the upscaling, deposterize shouldn't really cause much of a difference in terms of performance.

4. Super Advanced & Confusing 100% Speed Tweak
When I was playing Disgaea 1, I noticed that when VSync was on, my speed capped at 99.6%. This caused the audio to crackle ever so slightly. I think I read somewhere that the audio crackles and problems are mostly related to the game not running at 100% speed, as this decreases the interval in which the emulator processes new audio information. When the emulator is running at less than 100, it lags behind of where it should be. (This is my theory, not official information.)

So what I did was I set the Alternative Speed to 100% in the Graphics menu. Then in-game I just toggle the alternative speed mode on and BANG - constant 100% speed.

Why it does this? I don't know. It doesn't make any sense but it worked for me. On a side-note, doing this also decreased my input-lag and made the game feel more responsive.

If you want to find out more about the individual options, check the stickied guides that you can find from this forum. They are a great reference and helped me get started. For most tweaking, though - these are all the options you need.

I would hope that someone found some things from this post useful, as it took countless of hours to figure out why my audio wasn't playing back perfectly. I also wasted a lot of time trying to figure out a workaround from my broken ATI drivers.

Well - I'm loggin' off for now. Have a great day, everyone!

As far as I understand the PSP had a internal clock that not only showed you the time but also added some features to games. Monster Hunter Portable 3rd as an example checked for the time when you started it up and assigned you to different charm tables.

The problem is PPSSPP has no PSP main menu. You always start games right away and the clock always seems to start at 00:00 wich means Monster Hunter always assigns you to the same table.

So my main question: Is there a way to manually set the PPSSPP PSP's time? All I found was centered around the time format wich is not what I'm looking for. I scanned the config itself aswell.

I was playing Final Fantasy Tactics on Version 9.1 but I'd like transfer that data to the new 9.8 version. I tried copying the data and pasting it into the new version same location but that didn't work, then I reopened the old version did a manual save (like one would do at a save point) onto the memory card and I can't seem to open that either, saying it can't find any save data for the game and/or can't load save state.

What should I do?

Mine PPSSPP x64 all version cant play..the error was "The application was unable to start correctly (0xc000007b)." Really need help here.. Been a month havent play.

Guys help me plz im playing on Sony Xperia Z1 Compact isn't root yet I can can save my game but I can load the savefile ... its really boring to start over everytime I get on plz help

Hey everyone,

I've been trying like a madman to get the DLC tracks for Rock Band Unplugged to work and after days of trying I'm stumped.

At this point I don't know if it's the iso, the dlc tracks themselves or the file placement. They're supposed to go in the PSP/GAME folder, but that doesn't work. I've tried putting them in every single combination of folders related to both US and EU versions and still get nothing.

With a PSP CFW you're supposed to use npoloader, but that doesn't work, nor does unpacking the iso, adding the tracks and using umdgen to pack it back up.

I'd really love to play the dlc tracks, but I'm at a loss.
Can anyone help?

Hey guys, recently i discovered this maervelous emulator it works flawlessly on my high end gaming machine. regardless that i used it for a month now and found it performs exactly like an original psp, i could even import my original save files, but i want to play with my friends too, via hamachi and the adhoc stuff, they dont have powerfull devices such as me, and one of them is really struggling to get this Running, he has a laptop with 6gb ram and a core i3 540m with intel's HD2000, but the emulation doesnt pass the 20% speed, and i dont know what else to try


Regarding another manner, i have a tablet with embeded controls like a huge psp Vorago pad 301 runs a cortex a9 Quad core at 1.6ghz and has 1gb ram, but the emulator seems to lag at certain points, also the emulator cant recognize the 2 joysticks sepparetly, it fuses them with the other buttons, i would love any help please

Hey everyone,

i have an interesting story to share about something happened to me today while playing on the ppsspp emulator.

after i played many hours (patapon 2) and everytime i finish playing i press F2 to save the state then close it and when i come back i open the game and hit F4 to load and continue.

so today i open ppsspp and i open the game and the game starts and by mistake i press F2 thinking its the load button, and what do you know ? i over saved alllllll my work with a useless save T_T did anyone happen to be in that situation its funny and sad i dont know how i feel lol

Basically there is something I want to record but there is japanese lyrics over it that I'd like to remove

And I wanted to know if there is a way in PPSSPP to turn off specific textures. I was messing with the GE Debugger and found which textures they are (0x09d4b9b0 and 0x0a4ee830) but don't know if there is actually a way to turn them off.

Anyone know if it's possible to do?

i am playing god of war ghost of sparta, when i come to Thera in game, she asks to rotate, but i have no key to rotate in ppsspp. i have win 7, and xpadder is not working. in ppsspp windows, i can move forward backward left and right but not turn him or rotate
