YOU ARE ALLOWED TO COPY THIS GUIDE WHILE INCLUDING THIS DISCLAIMER AND PROPER CREDITS. IN OTHER WORDS, USE THIS GUIDE AT YOUR OWN RISK, BUT, ENJOY Added step (1-1-D) (formatting correctly) Added Requirement (0-1-B) Added a note about changing icons in the XMB (might cause brick) added Q/A (0-3-G) (MS from Fat to Slim) Added a tip at (1-1-R) (backup 2) Added Q/A (0-3-F) (MSPFORMAT / Vista) Changed step (1-1-B) to obsolete. Added step (1-1-C) (mspformat). Added more info in step (1-2-B) (flash process). Added info about 4GB sticks at (0-1-B). Added an alternative in step (1-1-M) (format). Changed "KN" folders into "KD" at (1-1-K) and (2-1-F). NOTE: Do not attempt to change any icons on the XMB, it seems that they implemented a check to see if the files are genuine, changing them might result in a semi-brick. NOTE:he steps for creating the battery are likely to change in the near future, Booster and Mathieulh seem to be working on a way to include multiple IPL's on one Magic Memory Stick, to make it both Fat and Slim compatible. For now, just follow the steps below. (0-1) REQUIREMENTS: (0-1-A) A "fat" PSP running firmware 1.50 or custom firmware, together with a non-el-cheapo battery. (0-1-B) A "slim" PSP running firmware 3.60, it is NOT possible to install this on a higher firmware version! (0-1-C) Memory Stick PRO duo, NOT a Memory Stick Duo, 64 MB should be fine, but must be 4 GB or less. (According to PROD, 4GB doesn't work at all, other people said that their 4GB did work) (0-1-D) AC Adapter. (0-2) TESTED ON: (0-2-A) White Fat PSP TA-082 (IC1003) with original 1800mA battery and firmware v3.52 M33 Update 4 (english) (0-2-B) Black Slim PSP with original 1200mA battery and firmware v3.60 (english) (0-2-C) Sony 2GB Memory Stick PRO Duo (0-2-D) Original AC Adapter (0-3) QUESTIONS/ANSWERS: (0-3-A) Q: I Only have a PSP Slim and no PSP Fat, can I install the M33 CFW? A: No, you must have a PSP Fat to create the Magic Memory Stick and Pandora's Battery. (0-3-B) Q: I did not backup the "KD" folder after creating the "ordinary" Pandora's Battery, now I can't turn my battery back to normal. Can you send me the proper files? A: No, but what you can do is boot up your Fat PSP without the Stick and Battery (use AC Adapter), then insert Stick and Battery and run "Pandora's Battery Creator". (0-3-C) Q: After I have created the Magic Memory Stick for the Slim PSP, can I still use it to unbrick/downgrade the Fat PSP? A: No, and that's why you should make a backup of the KD folder after making the "ordinary" Magic Memory Stick. Just put back the KD folder from the "ordinary" Magic Memory Stick and you can use it on the Fat PSP again, no need to modify the battery in any way. ( (1-1-J) and (2-1-F) ) (0-3-D) Q: Can I use the newly 3.60 M33 enabled PSP Slim to revert Pandora's Battery back to a normal one after the installation? Or do I have to use the Fat PSP? A: No, you must use the Fat PSP. (thanks DarkSeveN) The function to write the Battery's EEPROM was accidently left in 1.50, Sony removed it right after discovering that, so 1.51 or higher kernels can't write the battery's EEPROM. (0-3-E) Q: I can't see the two or three applications on the XMB after putting them in "GAME150". A: Try putting them in "GAME" or in "GAME352" (replace 352 with your version, example: you have 3.40 OE-A, then make a folder called "GAME340") (0-3-F) Q: I'm running Vista and I have a problem running MSPFORMAT, what can I do? A: Some people reported this problem, there seems to be no way around this at the moment (besides from running it on XP). I recommend to continue without the MSPFORMAT step, in some cases it works without it. (0-3-G) Q: I already have the Pandora Battery for the Fat PSP and want to convert it to the Slim, what do I have to do? A: Follow steps 1-1-F (copy over 'pandora_slim'), 1-1-H (copy over 3.40 and 3.50 updates) and 1-1-N (run 3.60 mem-stick installer). Basicly you just have to read the M33 Readme, you've already done that, right? (0-4) PRE-INSTALLATION STEPS AND NOTES: (0-4-A) Download Pandora's Battery here: http://forums.maxconsole.net/showthread.php?t=75759 (0-4-B) Download M33 Custom Firmware 3.60 here: http://forums.maxconsole.net/showthread.php?t=78493 (0-4-C) Download Official 1.50 Update here: http://www.psp-hacks.com/file/4 (0-4-D) Download Official 3.40 and 3.50 Updates here: http://www.psp-hacks.com/file/1130 and here: http://www.psp-hacks.com/file/1164 (0-4-E) Make sure the battery has enough power (how about 100% ? ) (0-4-F) I recommend taking a look at the Readme's from both "Pandora's Battery" and "M33 Custom Firmware 3.60". This way you'll not only see the procedure from my point of view. (0-4-G) When writing files to the memory stick, you can either do this by USB, or Card Reader, it doesn't matter apart from the speed. (0-4-H) I recommend to NOT press any buttons on the PSP until I have stated to do so. (0-4-I) If at any point your PSP won't turn on again because you already created the Magic Memory Stick or the Battery, take them out and use the AC Adapter to start the PSP, then put them both back in. (1-1) INSTALLATION PART 1: (1-1-A) Connect stick through USB or Card Reader to PC. (1-1-B) ( obsolete step, though it is in the Pandora's Battery Readme, the next step already does this part ) Format the memory stick, you can do this in many ways. Easiest would probably be with the Windows utility: My Computer > Right click the stick > Format > Enable "Quick..." > Start Or use a command prompt: (replace X: with your drive and MyLabel with any label you want) Quote: format X: /FS:FAT /V:MyLabel /Q /X (1-1-C) Open a Dos prompt (Start > Run > CMD > OK) and enter these commands, replace "C:\Pandora's Battery\mspformat" with the folder where your "mspformat.exe" is. Also replace X with the drive of your stick. Quote: CD "C:\Pandora's Battery\mspformat" mspformat.exe X It will ask: All data will be lost. Do you want to continue?. Type 'y' and press enter. It should then say: Drive succesfully formatted, and partition moved. Quote: If you think that's way to hard, try this: Start > Run > Type this and press OK: C:\mspformat\mspformat.exe X But, you must find out by yourself what the correct Path and Memory Stick drive-letter are (in example: "C:\mspformat\" and "X"). (1-1-D) Disable USB connection, remove the Memory Stick. Then re-insert the stick and enable the USB connection (or, eject from cardreader and insert again) (1-1-E) Create a folder on the stick with the name "PSP", in the PSP folder make one called "GAME150" (1-1-F) Copy these folders from the Pandora package to the GAME150 folder: "pandora_battery", "pandora_battery%", "pbfirm_install" and "pbfirm_install%" (1-1-G) Copy these folders from the M33 package to the GAME150 folder: "pandora_slim" and "pandora_slim%" (1-1-H) Extract "EBOOT.PBP" from the 1.50 update package and rename it to "UPDATE.PBP", then copy it to the ROOT of the memory stick. (1-1-I) Extract "EBOOT.PBP" from the 3.40 and 3.50 update packages and rename them "340.PBP" and "350.PBP", then copy them to the "pandora_slim" folder. (1-1-J) Put the stick in the "fat" PSP (or disable USB connection) and run "Pandora's Battery Firm. Installer" Once loaded, press X to create the required files on the stick and wait for it to exit to XMB. (1-1-K) Connect stick through USB or Card Reader to PC. (1-1-L) I recommend making a complete backup of the memory stick at this point. [backup 1] Keep the "KD" folder in a safe place if you want to use the Magic Memory Stick on the "fat" PSP in the future. (1-1-M) Copy the newly created "msipl.bin" from the memory stick to the "msinst" folder of the Pandora package located on your hard drive. (1-1-N) Open a Dos prompt (Start > Run > CMD > OK) and enter these commands, replace "C:\Pandora's Battery\msinst" with the folder where your "msinst.exe" and "msipl.bin" are. Also replace X with the drive of your stick. Quote: CD "C:\Pandora's Battery\msinst" msinst.exe X msipl.bin It will ask "Are You Sure ?[Y]", type 'y' and press enter. You now have created the original Magic Memory Stick Quote: If you think that's way to hard, try this: Start > Run > Type this and press OK: C:\msinst\msinst.exe X C:\msinst\msipl.bin But again, you must find out by yourself what the correct Path and Memory Stick drive-letter are (in example: "C:\msinst\" and "X"). (1-1-O) Put the stick in the "fat" PSP (or disable USB connection) and run "Pandora Ext. for Slim 3.60 M33 Installer" Once loaded, press X to create the new files on the stick and wait for it to exit to XMB. You now have created the Magic Memory Stick for the "slim" PSP. (1-1-P) Run "Pandora's Battery Creator" (1-1-Q) First press "triangle" to backup the battery's EEPROM to the stick, you can use this to restore it to a normal battery later on. It's also possible to restore without the EEPROM backup, though it is unclear what the difference is. (1-1-R) Press X to convert your battery to Pandora's Battery. (1-1-S) Again, I recommend to make a backup, at least backup the "eeprom.bin" that you (might have) created earlier. [backup 2] Keep the "KD" folder in a safe place if you want to use the Magic Memory Stick on the "slim" PSP in the future. (1-2) INSTALLATION PART 2: (1-2-A) Make sure the "slim" PSP is off. Put the SLIMinized Magic Memory Stick and Pandora's Battery in it. I was having a hard time slamming the "fat" battery into the "slim" PSP, but you just have to push it hard until you hear a click. It should turn on by itself, though you won't see anything on the screen. (1-2-B) You have several options here, if you just want to modify the firmware to M33, press X. This shouldn't take more than a couple seconds, and then it will turn off automaticly. Other options are "Square" and "L + R + triangle", the use of these options are out of the scope of this guide, refer to the Readme of the M33 package for more info. (1-2-C) Remove the Magic Memory Stick and insert the normal "slim" battery. Your "slim" PSP is now ready for use with homebrew! (2-1) RESTORE BATTERY TO NORMAL ONE (optional): (2-1-A) (Make sure you haven't deleted anything on the Magic Memory Stick inbetween the steps, if you did delete anything, at least put back "pandora_battery", "pandora_battery%" and "eeprom.bin") (2-1-B) Turn on the "fat" PSP without the Magic Memory Stick and Pandora's Battery inserted, but with the AC Adapter. (2-1-C) Insert the Magic Memory Stick and Pandora's Battery after it was powered on. (2-1-D) Run "Pandora's Battery Creator" (2-1-E) Press L-Trigger + R-Trigger to restore the battery to a normal one with the use of "eeprom.bin" You could get an error at this point: "Error writing at address 0x14". Ignore this error, it happens most of the times, if not always. Everything should be back to normal now. (2-1-F) If you want to make the Magic Memory Stick to work again for the "fat" PSP, just put back the "KD" folder that you backed up earlier. Have Phun!!
