[GUIDE] Installing TimeMachine Guide written by Moose_Island and JumpR and edited by users on PSPWIKI


This guide will help you install TimeMachine on your PSP. TimeMachine, for those who do not already know, allows the loading of previously released firmwares from the memory stick using a Pandora's battery. TimeMachine may not be of any use to the casual PSP gamer. But if you are a coder or dedicated hacker of the PSP, this allows you to test your code or hacks on older firmware for compatibility checks. The main reason TimeMachine is such a big deal is that it can run no matter the state the actual PSP is in, even if the NAND is destroyed. So here we have it, TimeMachine. This guide has been written by both Moose_Island and JumpR of QJ.

What will I need?[edit]

  • A PSP Classic (Phat) on 2.71 SE-A or higher.


  • A PSP Slim on 3.60 M33 or higher.
  • A USB Cable.
  • JigKick Battery (Mistakely known as a Pandora's Battery)
  • Memory Stick Pro Duo. 256 MB and higher.

Guides for creating a Pandora's battery can be found at the following sites: Or simply download the Cory149 tool somewhere and install on battery.

  • TimeMachine v0.1 Files: here.
  • Firmware file(s): Only download the firmwares which are stated in each guide section.
  • 1.50 EBOOT.PBP - here
  • 3.40 EBOOT.PBP - here
  • 3.60 360.PSAR FILE MUST BE OBTAINED VIA PSP SLIM USER! Can be obtained off torrents or storage websites. Might be a link in other guides.

Limits and Functions[edit]

Currently only the following firmwares are supported for loading by TimeMachine:

Classic PSP: Offical 1.50, 3.40 OE. Slim PSP: Modified 1.50 (with 3.40 modules for Slim support), 3.60 M33 Dark_AleX also notes that other custom firmwares will be added in the future.

In order to use it, it doesn't matter what firmware you have. However, in order to boot from the internal NAND, you need at least 3.90 M33-2 on the Slim, it doesn't matter what firmware you have on the Classic PSP.

Installing TimeMachine[edit]

Installing TimeMachine is pretty easy, make sure you have a Pandora battery ready. A Pandora memory stick isn't necessary but highly recommended, as that'll allow you to install a custom firmware from the same Pandora set. You don't even have to format your memory stick!

1. Extract the TimeMachine file you downloaded above to your desktop.

2. Enable USB on your PSP and browse to X:/PSP/

3. Create a folder named GAME*. Replace * with your firmware (e.g. 3.71 M33 would be GAME371). If on 3.90M33 you must name the folder GAME380 (due to a small bug). Or simply put it in the GAME folder and make sure your kernel is set on your firmware and not 1.50 kernel on fat PSP's.

4. Copy the 'TIMEMACHINE' folder (from your desktop) into 'X:/PSP/'.

5. Toggle off USB, and browse to the Game > Memory stick on your PSP.

6. Launch the TimeMachine installer.

7. Choose 'Install iplloader on PSP MS boot sector'

8. After it finishes, it'll return to the menu. Now start to prepare your memory stick with TimeMachine things, like firmwares.

Convert Pandora IPL into TimeMachine Format[edit]

This will allow you to use the default Pandora options like installing a firmware from TimeMachine, this requires that your memory stick had DC1-4/normal Pandora installed before this.

1. Load the TimeMachine application via GAME > Memory Stick.

2. Make sure you have msipl.bin in the root of your memory stick. If you do not have this file you will need to create it using the Pandora installer (guide above).

3. Select the option 'Convert Pandora/DC1-DC4 ipl into TM format' from the menu.

4. Continue to another option or exit.

Installing Firmware[edit]

It is perfectly suitable to click all of the firmwares available and have them all on one MS. This is not harmful to the PSP, even if you install slim firmwares on fat or fat firmwares on slim. Just remember after that not to press the 3.60 M33 button on fat or orginal 1.50 or 3.40 OE-A button on slim when used with pandora's battery. To reduce risk simply install all firmwares available for your PSP type. Example for Fat install 1.50 MIX, Original 1.50 and 3.40 OE-A only. For Slim install 1.50 MIX and 3.60 M33 only. If you are pretty sure you are not going to press anything wrong do them all. Or if you are planning to do it on other PSP's just install all, you will save time.

Classic PSP only[edit]

Installing 1.50[edit]

This will allow you to run 1.50 from the memory stick.

1. Download the 1.50 EBOOT.PBP and rename to '150.PBP'.

2. Place newly renamed 150.PBP in root of memory stick.

3. Run TimeMachine Installer and select the option which is 'Install 1.50 (PHAT)'.

4. Continue to another option or exit.

Installing 3.40 OE[edit]

This will allow you to run 3.40 OE from the memory stick.

1. Download the 1.50 EBOOT.PBP and rename to '150.PBP'.

2. Place newly renamed 150.PBP in root of memory stick.

3. Download the 3.40 EBOOT.PBP and rename to '340.PBP'.

4. Place newly renamed 340.PBP in root of memory stick.

5. Run TimeMachine Installer and select the option which is 'Install 3.40 OE (PHAT)'.

6. Continue to another option or exit.

Slim PSP Only[edit]

Installing 3.60M33[edit]

This will allow you to run 3.60 M33 from the memory stick.

1. First you must dump the 360.PSAR from a PSP Slim running 3.60M33: Run the program 360DUMPER that is found in the TimeMachine Files on a psp running 3.60 M33.

2. The PSAR can be checked against these MD5 and Size checks to make sure it is useable:

  • Size: 18189502 bytes.
  • MD5: EAA13343C70D9B0337C75B295 474C69A

2. Once done, place the 360.PSAR in the root of your memory stick.

3. Run TimeMachine Installer and select the option which is 'Install 3.60M33 (SLIM)'.

Both PSP's[edit]

Installing 1.50 with 3.40 HW modules[edit]

This will allow you to run 1.50 on the Slim.

1. Download both 1.50 EBOOT.PBP and 3.40 EBOOT.PBP from above.

2. You will need the 3.60 PSAR file which can only be obtained by the following method: Run the program 360DUMPER that is found in the TimeMachine Files on a psp running 3.60 M33. If you already have it place it in the root of your Memory Stick.

3. Rename them from 1.50 EBOOT.PBP -> 150.PBP and 3.40 EBOOT.PBP -> 340.PBP.

4. Place both of the newly renamed eboot's in the root of your memory stick along with the 360.PSAR.

5. Run TimeMachine Installer and select the option which is 'Installing 1.50 with 3.40 HW modules (PHAT & SLIM)'.

Using TimeMachine[edit]

Last but not least, how do you use it?

1. Pull in the TimeMachine memory stick and Pandora battery (in that order).

2. Whilst pulling in the battery (or turning it on if you had it in already), choose one of the following options:

  • Cross: 1.50
  • Circle: 1.50 modified for Slim support
  • Triangle: 3.40 OE
  • Square: 3.60 M33
  • UP Button: Pandora/DC1-4
  • Anything else: Will boot from internal NAND chip (requires 3.90 M33-2 or higher on the Slim)

DO NOT TRY 3.40 OE-A OR ORIGINAL 1.50 ON SLIM OR 3.60 M33 ON PHAT!!!! If successful, it will load up like a brand new PSP and you will have to choose your settings. Those settings will be saved so that it won't ask again next time. After that there you are; on the time machine firmware. To switch to another firmware; make sure you have installed that on the menu; turn it off and turn it on again with the correct button. To move back back to your custom firmware before; simply turn it off, and when turned on don't press anything. To use the TM firmwares, you'll will have to leave the Pandora's battery inside. The Time Machine Firmwares are not permanent and you can only use them with a pandora battery. Without one you will just be on your normal firmware. Now enjoy 1.50 Homebrew ALL PSP USERS!!!


I bricked, what can I do? It's close to impossible to brick with this, try starting your PSP with the AC adapter and then turn your battery back to normal.

Flash USB from custom firmwares doesn't work, how can I solve that? The TimeMachine core replaces the flashing functions, and there is no point in using those as the firmware is on the memory stick and you can simply modify it on there.
