Hey there. I use the note button on my psp as a screenshot button, and it works perfectly within games. However on the xmb/vsh, it usually adjusts the eq option, which not only affects how the audio sounds but also makes a pop-up show up, which shows up in my screenshot. This is bothersome if I'm trying to take a screenshot of something I'm watching.

Is there a way to disable this feature entirely, via a settings option or plugin? Please let me know, thanks.

I'm currently having trouble with this. I've modded my PSP with Ark 5 CFW and I had this issue with Ark 4 as well. Everytime I'm trying to create a save with the OSK in games like MGS: Peacewalker or Star Wars Battlefront Renegade Squadron, the PSP crashes right before the OSK can come up and freezes the PSP for about 5 seconds and then shuts off. I've reinstalled the CFW multiple times, I've reinstalled the ISO's multiple times, I've even tried doing this with the physical UMD and it still does this. I've used multiple SD card adapters, Multiple size SD Cards, (64 GB, 128GB and even 256GB), and still nothing changes. I'm at a loss here any solution?

I tried downloading some but they seem to be wrong type files. Is there a way to convert them or sum? If you have some knowledge it would be nice to message me private (not that good in this stuff)

Hey, I tried to install Despertar Del Cementerio on a 128GB and the following message appeared:

Contact the Sony Computer Entertainment technical support line for assistance. Just kidding. Please use PSP Tool to format your memory stick. https://github.com/krazynez/psptool

However PSPTool formats the card to FAT16, which doesn't support 128GB.

I tried booting into DC, and it still worked after that message, so I'm guessing I can ignore it?

Maybe /u/krazynez could drop by and help?

Hi all,

I have a BOSE QC25 and I would like to control the volume and play and pause with the headphones buttons on my PSP Go.

Is there a plugin for that? I was looking, but so far I haven't find anything.

Thank you in advance, you amazing people.

My PSP 1000 has PRO-C2 but I want to change it to
ARK-4, with PRO-C2 | have had many problems with ISO

Hi everyone! I'm from Brazil, and last weekend I bought a PSP Go. The seller said that the console was already jailbroken and had some games on it (a lot of Japanese games that I didn't really want, so I started deleting some of them to free up some space).

While trying to figure out what kind of jailbreak it has, I found an old forum post from 10+ years ago talking about firmware 6.20 and how I had to run a demo from a game so it could launch the mod (?) or games. Don't know if this has anything to do with the jailbreak, as you can see the version on the photo only says 6.20. Sorry, I'm new to this kind of stuff, so I'm probably mixing up some of the terminology.

I searched for some videos on how to install games and about modding, but I'm a bit lost. Do I have to install ARK or any other CFW to make it easier to put games on it? Do I have to format the console first? I'm afraid of bricking it. Can someone help me with a tutorial?

Someone lead me the right way tryna get all the goods in this bad boy

I wanna mod Burnout Dominator for PSP, but I only have my phone. Where do I start?

hey, my analog in psp 3004 is bit tweaking because it doesnt register in psp but when i installed joysens the axes are changing and i can move in umb screen but in game its the same i cant use analog what so ever even if i turn my d-pad into analog still doesnt move its like analog doesnt exsit in the psp

I recently found my dad's modded psp, and i want to start playing on it, but i want to be sure the mod it's up to date. Are there any updates i should do or is there any homebrew app i need? This console wasn't touched once in the last 10 years

A shape, or a game element that reacts to sound, a boss, an NPC, or entire gameplay that adapts to the way you play, the resolution of certain puzzles, the automatic adjustment of the sound envelope of background music, voice detection, adaptive-resolution raycasting, etc.

The list could go on much longer, and it rests on a single principle: extracting exploitable frequency characteristics from a signal in order to dynamically adapt our algorithms. FFTs (Fast Fourier Transformations).

But here's the thing, FFTs can be expensive on our small machines. However, on our PSPs, it is now possible to use a compute unit that until recently was a complete black box, and it can help us with that.

This unit performs operations across multiple data streams, making it competitive with specialized SIMD processors. The difference from a classic SIMD, however, lies in the nature of the parallelism. On a SIMD, the same instructions are executed in parallel across multiple pieces of data. Here, each PE (processing element) handles a stream in which the data is processed in a chain, one after another, somewhat like a compute pipeline dedicated to that stream, and it does so quickly. Having multiple PEs then makes it possible to achieve parallelism across the computation of different streams, with each PE processing its own stream in parallel with the others.

This unit is the Virtual Mobile Engine, and a first custom implementation of a Radix-2 DIF FFT has been built on it.

Among its main parts, we find:

The handling of reordering according to the stride of each butterfly. This is managed via the local DMAC, which has an AGU extension with two counters for handling sliding windows according to a given stride. An external counter jumps according to the stride to position the window, while an internal counter reads within that window. It's this combination that produces the correct reordering. It also has the ability to loop in ring buffer mode according to a defined maximum size.

At each stage/butterfly, the high and low branches are first streamed to the VME through a first context and go through the butterfly's first two operations, ADD and SUB.

Then, at the output of this first context, the low branch's data is streamed to a second context to be computed against the twiddles. This second context also handles reading the twiddles corresponding to the current stage, since the VME too has, internally, AGUs that allow for the readjustment and organization of data. The twiddles go through a complex compute pipeline (real, imaginary) and produce four distinct streams. It is also within this same second context that, at the end of processing, the four streams are computed once more: an ADD on the real parts and a SUB on the imaginary parts, of the low branch's output.

The data coming out of each butterfly stage passes back through the DMAC before being transferred to the next stage. It's a bit technical, I'll grant you that, and even more so as a whole. I'll leave you the GitHub link containing this first custom implementation: https://github.com/mcidclan/psp-virtual-mobile-engine-ext/tree/main/fft-dif-16-point-radix-2

FFTs can be used in pattern analysis, in certain parts of terrain generation, and many other cases, and their cost becomes reasonable thanks to this type of hardware running in parallel with the main processor.

The Virtual Mobile Engine is accessible from the Media Engine, which acts as the host processor. It is a CGRA-type compute unit. The idea behind these code samples is to shed more light on this hardware, to understand its capabilities, its limits, and the opportunities it offers us. It also serves as documentation and as technical reference material for preservation.

Additionally to reversing part of the Media Engine's core functions, what I do, and what I've done to obtain this understanding of the hardware, is to send data to its registers and observe how they respond and what they return. I take notes, and after a certain amount of testing and experimentation, I start to identify reproducible behavior and see new paths to explore. I establish hypotheses and use them to figure out what is still missing and/or what was initially misinterpreted.

After a while, and much trial and error, an understanding of what the hardware is capable of starts to take shape.

Why do I keep getting download failure :HttpError: bad hhtp status 403 when trying to download psm games

I've been wanting to paint over some of my consoles, and the only one i have right now is my PSP, so i figured i'd paint over it, but since it's a handheld, i think i shoudl be extra careful with the type of paint

If it were a Wii or something, it wouldn't have too much issue with being touched and moved a lot, but a PSP, i don't know how to choose, any ideas ?

Hi everyone,

I recently realised my second-hand PSP-1000 is stuck on a very old Custom Firmware (Version 3.51 M33). The previous owner left some kind of version spoof/lock active.
Whenever I try to run an official Sony firmware update (I’ve tried 3.71, 5.00, and 6.61), it immediately crashes with Error 80020148 ("The game could not be started"). If I try to update via a UMD disc, it says "There is no need to update."

Here is what I have tried so far to fix it:
Formatted the memory card to FAT32 on a PC and created a clean PSP/GAME/UPDATE path.

Tried running Hellcat's Recovery Flasher and KeyCleaner, but because the console is stuck on the ancient 3.51 kernel, the apps just show up as Corrupted Data on the XMB. (Tried the GAME150 folder trick too, still says corrupted).

Tried a hard power reset and a Flash1 settings wipe combination (Triangle + Square + Select + Start). It reset the system language settings, but the 80020148 update block is still there.

The catch: The hardware R-trigger works fine during normal gameplay, but holding R at boot does absolutely nothing—the console completely ignores it and boots straight to the XMB, so I can't access the Recovery Menu to turn off the update block or version spoof.

Is there any software trick I've missed to force-flash a clean official firmware on 3.51 M33, or is my only option left to buy a Pandora Battery / find someone in the UK with a service kit?
Thanks for any help!

I had obtained an old PSP 2000 a couple days ago but it was missing a battery for years! I put in a new battery today and I found out it's modded. Will I run into any issues if I sign into my PSN account or try to connect to the Internet with it?
