Determining PSP firmware using box codes (Dec 23, 2007)

[NeilR]

This topic comes up often enough that I felt it was time to have a sticky.

It is well known that what can be done on a PSP is related to the firmware that the PSP is running. When selecting a new PSP at your local shop, you most likely would like to know what you're getting; here is how you can determine what firmware is loaded on that PSP.

This will be updated as the situation evolves. Typically, it takes a month or two before new firmware revisions start showing up pre-installed on new PSPs.

Box with code The label may look differently depending on your locale, but the code letter should be found directly under the voltage rating. These are examples of the label where the code is displayed: Spoiler for American (1.50): Spoiler for Australian (1.52): Spoiler for Asian (2.60): Spoiler for Slim & Lite (3.71): Here are known codes: [Last updated on Dec 23, 2007] no letter = 1.0 (Japanese Release) 1.5 (North-American Release) confirmed A = 1.5 confirmed B = 1.51 confirmed C = 1.52 confirmed D = 1.52 confirmed E = 1.52 confirmed F = 2.0 confirmed G = 2.01 confirmed H = 2.50 confirmed I = 2.60 confirmed J = 2.70 unconfirmed K = 2.71 confirmed L = 2.81 confirmed M = 3.01 confirmed N = 3.03 confirmed O = 3.10 confirmed P = 3.11 confirmed Q = 3.30 unconfirmed R = 3.40 confirmed S = 3.50 confirmed T = 3.51 confirmed NP = 3.60 (PSP Slim & Lite Release) confirmed NP A = 3.71 confirmed

Box with no code Please note that there have been cases where there has been no code placed on the box. These are typically value packs. One such example is: Spoiler for PSP Entertainment Pack w/ ATV: Offroad Fury (2.71):

Here is some background info outlining what is possible on each firmware:
Info originally posted in the Ultimate Newbie Guide to the PSP


Firmware

The most important part of the PSP is its firmware. Many owners refer to the firmware as the PSP’s OS (operating system) or BIOS (Basic Input/Output System). The firmware of the PSP is located in the PSP itself and not on your memory stick. The firmware on the PSP is replaceable/ upgradeable. Sony issues updates to the firmware every few months and adds new features. With these new features usually come security updates. These security improvements fix up holes in the firmware that may be accessible to the user. Sony does not like homebrew due to the piracy of UMD games on the memory stick and would stop it at almost any cost (Piracy/Isos/Loaders are discussed in a few sections below).
The Updates are downloadable on Sony's PSP website (Playstation.com) and only allows you to download the latest update. Once you have the update downloaded, move it to your PSP/Game/UPDATE folder (the eboot file) and it shall update your PSP. Once installed (the update) you can delete it from your memory stick


1.0 Firmware:

The first firmware version that was installed on a PSP is firmware version 1.0 (Japanese PSP’s only). This firmware version was pre-installed on the first PSP’s released. The 1.0 firmware is unable to be downloaded since it was never released as an update. You can find various dumps of the firmware, but these dumps are not complete. (Dumps are basically files from the 1.0 firmware that were dumped onto the memory stick). The 1.0 firmware allowed for unsigned code to be ran on the PSP, and all that was required was an eboot.pbp compiled file. This file was run straight from the PSP/Game folder located on the memory stick. (Homebrew code is described in the section: Memory Stick located under Games on the PSP)
-------------------
1.5 Firmware:

This firmware was the first update to the Sony PSP in Japan. This version was also pre-installed on the US PSP release. This update changes from 1.0 JP to 1.5 JP include: Support for German, Spanish, French, Italian, Portuguese and Russian language options on the PSP menu (it will not affect in-game menus), a setting to retain the screen mode on videos, and a quick-resume function to resume playback of audio and video after coming out of the PSP's sleep mode (it won't automatically keep playing the media file, but you can jump right into the track or movie exactly where you left off before sleeping.) Download the 1.5 update here: [Click Here to download] This update, however, did not allow for the execution of eboot.pbp files from the memory stick like the 1.0 firmware did

After a few months of the US PSP release there were rumors of people finding a way to run homebrew on this new 1.5 firmware. Many did not believe this at first, but a few days later, on June 15th, they had to. You can find this news-breaking coverage at the following link: [Click here to view the PSPUpdates.QJ.Net Article] Two days after this hack of the 1.5 firmware, a safer exploit was produced. The previous exploit required two memory sticks that you switched once the PSP booted the split eboot (The file is split using the KXploit program that PSP-Dev created.). The new method does not require this and only requires the original MS1 folder contain a % at the end and the second folder to remain the same name. This was a major accomplishment.

To find out how to install these 1.5 homebrew, please read below for further instructions.
--------------------
1.51 Firmware

The second update for Japanese PSP’s (first for the US) was the 1.51 update. Update changes: The new Firmware update fixes various security issues in the PSP's v1.0 firmware which effectively fills holes to stop unsigned code from being executed.

As stated above, this new firmware does not allow for unassigned code to be run on the PSP (same as 1.5 but with heightened security). At the current time homebrew code is unable to be ran on this firmware; read the section on 2.0.
------------------
1.52 Firmware

The third update for JP PSP’s (2nd for US) was the 1.52 update. Update changes include: UMD Music to be run from the main menu and higher security.
Once again, homebrew can not be run on this firmware version; read the section on 2.0.

Updated parts of the firmware include:

• [Network Remote Play] Remote play is a new feature in Firmware 3.00 that allows you to remotely control your PlayStation 3 from your PSP. This also includes the display of PS3 content on the PSP. "You can display a PLAYSTATION®3 system screen on a PSP* system and play content that is on the PS3* system. To use this feature, you must adjust the necessary settings on the PSP* system and the PS3* system." Using this new mode of playback, one can control the Photo, Music, Video, and Internet Browser features of the PlayStation 3 from a remote location via their Playstation Portable.
• [Video Compatibility] In this updated version of the Playstation Portable firmware, you are also able to play a few new video formats. The Motion JPEG format (M-JPEG), is an "informal name for multimedia formats where each video frame or interlaced field of a digital video sequence is separately compressed as a JPEG image" (Wikipedia). The PlayStation Portable plays both the Linear PCM and the ?-Law versions of the Motion JPEG video format. In addition, you will now be able to access the Camera (functionality) from the photo option menus, for quicker easier access when taking photos or video. Another nifty function is the ability to finally turn off Auto Play for inserted UMD Discs via UMD Auto Boot.
• [PS1Games] Here's the big tip you've been waiting for. Finally, Sony is going to drop their highly anticipated PlayStation One emulator onto the PSP. From the manual however, there seems to be a unavoidable catch. If you don't have a PS3, your not going to be enjoying PlayStation One games emulating on Sony's PlayStation One emulator for PSP anytime soon. From the manual it states that you must connect to the Playstation Online store with your PSP connected to the PlayStation 3 in order to download and play the games. In addition, they mention that you can in fact share the games, but you must activate the other system in the Friends menu as a PS3 Network Account.
