    For homembrew software you can now go here

    In the past some TA-082 / TA-086s were downgraded in a fairly botched fashion. There's a tool to help anyone suffering from this here.

    If you're stuck on 3.11 for example you can also look at this specialist downgrader/upgrader.

    --------------------

    Slim PSPs have their own firmware already here:
    You do need a CFW enable fat PSP to do this ( it uses the Pandora battery trick ) and you won't be able to run a lot of homebrew yet because you won't get the 1.50 kernel. ( infact almost everything on my other list is 1.5 only ).
    But this will change and some things like iRShell already work.

    Upgrading / Downgrading ( Fat PSPs ):
    For all this stuff you do need version 1.5 firmware, so how to get there?

    If you have 3.51+ then you need to do the Pandora battery trick which does either need a homebrew PSP or an ebayed Pandora battery.
    Look here.
    REQUIREMENTS
    Requirements
    * Software Requirements
    o Pandora's Battery Files
    o 1.50 Sony Update
    o WinRAR or 7-Zip
    * Hardware Requirements
    o Two separate PSPs:
    + A PSP you want reflashed
    + A non-bricked PSP to prepare the files on. This PSP must also be capable of running 1.50 homebrew.
    + In theory, this could be done with one PSP. However, this PSP would need to be non-bricked, and capable of running homebrew. It would be much more efficient to use a homebrew flasher in that case. Therefore, the Pandora Battery should only be used to downgrade PSPs or un-brick PSPs.
    o A spare battery, of any make. After this process is complete, the PSP will not boot into its normal state with this battery
    o A spare Memory Stick Pro Duo, at least 256MB, less than 4GB. The Memory Stick Duo will not work, it must be a Memory Stick Pro Duo.

    For 3.50 and below it's not so bad:
    There are links to lots of FAQs and manual guides here.
    or
    This is now very simple for Windows users:
    With from this page you'll get everything you need to downgrade any machine here if it's below fw 2.81

    The guide program will point you to all the programs you download and explain how to use them.... watch out for the motherboard type bit.

    Basically the tasks for 2.80 and below will be:
    Get it to 2.80
    Install and run the downgrader

    For fw 2.81-3.50 you need Lumines.
    Then you should download the downgrader here and follow the instructions in the How to.
    Also be aware
    If you have a TA082+ motherboard and you downgrade to 1.50, currently you will be unable to upgrade to 3.30+ Sony firmware. This is due to Sony blocking updates when the PSP has been modified to run 1.50. There will be an application released later which will allow users to revert the changes. If you are using a TA082 motherboard then I would suggest just using 1.50 or OE until an application is released.

    With the later motherboards ( TA- 082+ ) you might have some problems with keys especially if you've used older downgraders.... have a look here for Keycleaner

    Now we've got 3.90 M33

    First you need to be on on 3.52-4 CFW / 3.60 CFW for slim already, so scroll down if this is done already.

    Installing M33 3.52 Custom Firmware:
    No easy updater about for this so here we go:
    Download the original 1.50 firmware, the 3.52 Official firmware, the M33 Custom firmware and the version 4 update.
    Then:
    only if you have 1.50:
    1 - If you are under official 1.50 PSP firmware, copy kxploitpatcher and kxploitpatcher% folders from "1.50only/" of this download to your "ms0:/PSP/GAME/" and use it.

    Next
    Grab the cfw here and the Sony fw fromhere.
    [code]Installation:
    * Copy the UPDATE folder into /PSP/GAME/
    * Get the 3.90 Sony update below, rename to 390.PBP, and put it in same folder.
    * Run it
    [/code]
    No Popsloader for 3.90 yet.
    Popsloader is a bit more complicated because you need the popsloader files from the archive in seplugins and then find from somewhere the correct .prx files that have been ripped from the different prior firmwares to put in the popsloader directory which you just put in seplugins.
    There is a guide here.

    Finally for Phat PSPs only there's 1.50 emulation these days there isn't much need.
    [code] * Copy the 150k_addon folder into /PSP/GAME
    * Rename the 1.50 fw. to 150.PBP
    * Copy it to the root of your memstick
    * Run the installer on the PSP
    [/code]

    There's a compatibility list here for the PS1 games

    And if you need older versions the emulator to make your game work you can download Popsloader here.

    Yet another PSP Tool Kit seems a good tool for converting you're PSX games, compressing stuff and other general management stuff.

    Also hit R while booting the machine and get into the recovery menu to disable UMD booting and overclock it, get plugins running etc.

    ----------------
    To rip and compress your games TT has done a nice write up:
    terminalterror wrote:
    I use USBSSS to rip my UMDs to an ISO file on my PC.

    You can then either place that directly on your memory stick, or compress it to a CSO with YACC.

    The readme that comes with USBSSS is really easy to follow. You install it in your GAME folder like any other homebrew. Put your UMD in the drive, connect a USB cable, then run USBSSS. Choose the first option, and your PSP shows up on your PC as removable storage, with a single file in it. Copy and paste that file to your PC. It'll take some time as the PSP has to read the entire UMD, so wait until the PSP screen says 100% (the readme says wait till it goes back to 0% but that never happens for me and it works fine).

    Now you can rename the ISO (they all have the same name normally) and copy it to the ISO folder on your memory stick.

    Now your game appears on the Game menu on the XMB.

    Really quite simple.

    Compressing the games down using YACC is really simple too. You just run it, point it at the ISO you want to compress and start it. Out comes a compressed file that you can also put in the ISO folder on the PSP and will run just the same as an ISO, with fractionally slower loading times.

    The CSO file can sometimes be massively smaller than the ISO, sometimes only a little. GTA doesn't like being a CSO though as it streams data all the time and jerks as the PSP decompresses it.

    Top YACC tip: run it in level 1 instead of the default level 9. Your CSO file will be about 1MB bigger, but it'll load quite a bit faster.

    ----------------

    If you ever want to rip to your PSP without having a PC available this still works.

    -----------------

    If you've still got certain ISO's giving you problems:
    Devhook is pretty useful. Apparently some games will run a bit smoother with it, so worth a look if your having some issues.

    It is absolute class... and it's the plug-in that IRShell uses.

    Personally like loading them through IRShell, but if you can't be arsed then the seperate version is better :D

    Adding now.

    If you downgrade, does that mean you can't play Tekken?

    I saw somewhere it needs 2.6, so no, you won't be able to play it.

    You can play any game. Devhook emulates the later firmware versions upto 2.71.

    Added a GBA emulator that's rather good.

    Thanks everyone.

    It just so happens that quite a few areas that the PSP is very useful for fit my needs so I end up spending a lot of time reading about stuff.

    I like messing about with the emulators... but I use a lot of the streaming stuff at home and the book reader all whilst on public transport.

    I have one question about the custom firmware before I try it. Once you've ran the relevant program is it safe to format your memory stick or use another memory stick in the PSP. I often format to get rid of old emu and other homebrew files, aswell as when I update devhook.

    Very sensible question. I played around with this a bit myself.

    It does stick one folder called CASUAL in the root of your memstick.

    If you delete it then it goes back to booting normally... but it is required to unistall the mod.

    You can access the setting menu by booting it while pressing the 'select' button.

    So if you dont have the files it needs it will simply boot like a normal PSP? Can play games, run devhook,etc? It wont just not boot or anything? If thats the case I'll probably give it a try as at least i can access and use the PSP. After using it for a while would you say it's worth it?

    Exactly.

    As to if it's worth it?

    Reboot your PSP and not have to open your UMD drive to prevent it booting the game? Hell yes.

    As to iR Shell? Personally I never use the XMB anymore! But you can start by booting to the XMD and change that later.

    I do use it a lot for reading books because finding them in Thailand is a right pain so I have a real need for it.
    I also use the wifi connection to stream mp3's to it when I'm reading in bed.

    Sounds good to be, I'm going to give it a go when I'm not half asleep as its something that can't afford a stupid mistake. I'll post here with how I get on.

    Edit: Well I just flashed it and the PSP still works so I guess it went well. Not had a play with the options yet, I'm about to give IRshell a try.

    Whats's some of the cool stuff IRshell can do? From a quick look it doesn't appear all that better than the original interface. Also when you boot devhook from in IRshell it asks if you want to go to the XMB or boot the inserted UMD. If you select the XMB it uses a fake iso. Is there any way to make it see the actual inserted UMD instead? Having to exit back out to IRshell to play is a bit of a pain.

    Ahh thats pretty cool. Beats messing around trying to get the custom sound track working in GTA. Do you know if there is a proper way of opening ebooks? Only way I found was to manually browse for compatible files.

    I dont use it so I'm no expert, but one of the things that makes iRShell so popular is that you can multitask. ie. You can listen to mp3's whilst you look at your pics or read an eBook with Bookr.
    That's why I started using it.

    Another cool feature is being able to use access files off your computer over the network ( but not games )

    Personally I don't use the iR SHell Devhook, but the one that I used before which is in my app's folder.

    If they added a calendar it would be cool.

    They wont be adding anything unless someone else decides to take over, the guy who made it has now stopped development of IRshell. I'll probably use the old devhook too, I liked the guimod for it. Is there a specific way to get to pdf,txt files, or do you just have to manually search via the memory card icon?

    Edit: How do you get the PSP to autoboot IRshell?

    Edit2: Well found where to change it, its in the config.txt file, although despite it saying you'll never need to edit it manually I cant find a way to get the initial menu requesting mode back. When I did manually edit the path through a copy and paste the PSP wouldn't boot with the memory card in. I deleted the whole casual folder and put the one from the downloaded archive again and it worked so I now boot right to IRshell. Although if you know I'd REALLY like to know how to get it to ask again on boot if I want to use the XMB or Shell boot. Not on every boot, just so its possible to change if I choose too, without relying on a PC.

    I know he's not going to update it... just wishing :p

    Though nothing to stop us using alternative programs.

    As to the booting.... turn it on whilst holding select and you'll get the menu.

    I suppose for me the only reason I'm using iRShell is that it's easier to access my books from it and then swap directories to my apps folder by pressing square a couple of times.

    I've changed the Photo folder to a different folder where I store my mp3s and books.

    But I didn't start booting to it till I'd sorted the WiFi file link. That's very nice since I just plug it into the stereo in whatever room I'm in and stream my Mp3's to it when I'm in the house.... or wander around with headphones on using it as a walkman.

    You can also stream pre-converted video files if you want but I use other stuff that means I don't have to pre-convert for that.

    Which does bring up one other benefit... if you load homebrew from iRShell and the homebrew crashes you can normally. get back to iRShell, rather than needing to reboot.

    I guess I'm just booting into IRshell atm because I just like messing with things, often more than playing the games themselves. I was the same when I first got my modded xbox. I cant stream to the PSP as I dont have a compatible access point, all I have is the Nintendo one for the DS.

    I had a play about with the SNES emulator earlier, seems to be pretty good!

    Mario Kart and Yoshi's Island run a bit slowly (they both had the extra DSP chips so have always required a bit more grunt to emulate), but SMW runs beautifully.

    I need to dig out my old SNES rom collection...
