ScummVM has been ported to the [[Sony]] PlayStation Portable.  
  
= Installation =
+
For more information, including how to install and use ScummVM, see the [https://docs.scummvm.org/en/latest/other_platforms/playstation_portable.html PlayStation Portable page] in the [https://docs.scummvm.org/ ScummVM user documentation]
First, look up the version/firmware for your PSP. You can do this by going to system settings and then system information.
 
  
You will get 3 lines:
+
== Image viewer ==
<pre>MAC Address: (Your PSP's specific MAC address)
+
For your convenience, I've included a simple image viewer in the PSP port.
System software version: (Your PSP's firmware version)
+
You can view anything you want while playing a game.
Nickname: (The nickname you put onto PSP)</pre>
+
There are a few simple rules to follow:
  
 +
* Images must be of PNG format. If you have images in another format, many graphics utilities will convert them for you.
  
== Firmware Versions ==
+
* Images must be named psp_image1.png, psp_image2.png etc. This is to make sure there's no possible conflict between image files and game files.
There are 28 different firmware versions:
 
  
=== Official Versions ===
+
* Images must be placed in the game directories. When using the image viewer,only the images of the particular game being played will be available for viewing.
*1.00
 
*1.50
 
*1.51
 
*1.52
 
*2.00
 
*2.01
 
*2.50
 
*2.60
 
*2.70
 
*2.71
 
*2.80
 
*2.81
 
*3.00
 
*3.01
 
*3.02
 
*3.03
 
*3.10
 
*3.11
 
*3.30
 
*3.40
 
 
  
=== Unofficial Versions ===
+
* Don't place any images in the ScummVM directory, or you won't be able to seethe images in the game directories.
  
*1.50 CF (Custom Firmware, Shows as 1.50)
+
* There's no guarantee that you'll be able to view your image. This is because big images take a lot of memory (more than the size of the image on disk). If there isn't enough memory left to show the image, ScummVM will tell you so. Try to make the image smaller by either shrinking it or reducing the colors to 256 color palette mode.
*2.71 SE (Special Edition) (5 different versions; A, B, B', B" and C)
 
*3.02 OE (Open Edition) (2 different versions; A and B)
 
*3.03 OE (Open Edition) (1 version; A)
 
*3.10 OE (Open Edition) (2 different versions; A and A')
 
*3.30 OE (Open Edition) (2 different versions; A and A')
 
*3.40 OE (Open Edition) (1 version; A)
 
  
== Installing onto Memorystick ==
+
== Developer information ==
Now that you know your firmware version we can begin with the installation instructions which are different for the firmwares, depending on the exploit they are using. <tt>X:/</tt> is the drive given to your PSP by windows (i.e. <tt>G:/</tt>). XMB stands for Cross Media Bar, which is the menu you get on your PSP (also on PS3).
 
  
=== Firmware 1.00/1.50 CF - No Exploit ===
+
=== Building from source ===
Firmware 1.00 needed no exploit to run homebrew as there was no security against the system from running unsigned eboot.pbp's. Firmware 1.50 CF patched a PSP running a regular firmware 1.50 so that it could run unsigned eboot.pbp's like firmware 1.00 (among other features).
+
To build ScummVM for PSP you need:
  
To install ScummVM on one of these firmwares, copy the folder inside the single-eboot folder from the ScummVM PSP zip to <tt>X:/PSP/GAME/</tt>. Then run from the XMB.
+
* ScummVM source code (svn co https://scummvm.svn.sourceforge.net/svnroot/scummvm/scummvm/trunk)
  
=== Firmware 1.50/1.50 CF - kxploit ===
+
* PSP toolchain (svn co svn://svn.pspdev.org/psp/trunk/psptoolchain)
Patching the vunerability that firmware 1.00 had, firmware 1.50 was released. Shortly after, an exploit was found, 'swaploit', which involved swaping between two memory sticks which enabled the homebrew to load. Later, kxploit was released which could load homebrew from one memory stick using 2 folders (i.e. <tt>example</tt> and <tt>example%</tt>)
 
  
To install ScummVM on one of these firmwares, copy the folders inside the 1.50-eboot folder from the ScummVM PSP zip to <tt>X:/PSP/GAME/</tt>. Then run from the XMB.
+
* PSPSDK (svn co svn://svn.pspdev.org/psp/trunk/pspsdk)Note: This usually gets installed by the PSP toolchain, so you don't have to do it manually.
  
=== Firmware 2.00/2.01/2.50/2.60/2.70/2.71/2.80 - Eloader ===
+
* zlib (svn co svn://svn.pspdev.org/psp/trunk/zlib)
It was firmware 1.51 that blocked kxploit, but many PSP users refused to update. This caused Sony to release a major update that would tempt people to update. Thus, firmware 2.00 was released which came with a built-in web browser, and caused many PSP users to update. However, one of the new features brought two new exploits (both are TIFF exploits). The first was exclusive to 2.00 and was patched with 2.01. The second wasn't discovered until after firmware 2.80 was released, a vulnerability with libtiff. Team Noobz has built on these exploits to bring the homebrew community Eboot Loaders (called Eloader)
 
  
To install ScummVM on one of these firmwares, copy the folder inside the single-eboot folder from the ScummVM PSP zip to <tt>X:/PSP/GAME/</tt>. You now also need to install Eloader, the newest version of which can be found at [http://www.noobz.eu www.noobz.eu]. Download the exe and follow the instructions to make sure you install successfully. Once you have Eloader installed, turn your PSP on and go to the XMB photo viewer. There should be a new folder called eloader0995. Trying to open this folder will do one of two things:
+
* libPNG (svn co svn://svn.pspdev.org/psp/trunk/libpng)
  
# Crash your PSP. If this should happen, restart your PSP and try again.
+
* libmad(x) (svn co svn://svn.pspdev.org/psp/trunk/libmad)
# Start Eloader. Run from Eloader menu.
 
  
=== Firmware 2.71 SE/3.02 OE/3.03 OE/3.10 OE/3.30 OE/3.40 OE ===
+
* libTremor(x) (svn co svn://svn.pspdev.org/psp/trunk/libTremor)
All of these custom firmwares were made by Dark_AleX. They combine firmware 1.50 with another firmware (as stated in their names) so PSP users can play homebrew and use higher firmware features (most recently POPS the official PS1 emulator), without needing devhook, two PSPs or a modchip.
 
  
To install ScummVM on one of these firmwares, copy the folders inside the 1.50-eboot folder from the ScummVM PSP zip to <tt>X:/PSP/GAME150/</tt>. Then run from the XMB.
+
(x) = optional
Alternatively, copy the folder inside the single-eboot folder from the ScummVM PSP zip to <tt>X:/PSP/GAME150/</tt>. Then run from the XMB.
 
  
=== Firmware 1.51/1.52/2.81/3.00/3.01/3.02/3.10/3.11/3.30/3.40 ===
+
Once you've installed these libraries (read their README.PSP for instructions), create a subdirectory in your ScummVM folder called 'builds/psp'. Then, in this folder, type
Currently there is no exploit that allows you to run unsigned eboots on these firmwares. 1.51, 1.52, 2.81, 3.00, 3.01 and 3.02 can upgrade to a higher firmware that runs homebrew.
+
    ../../configure --host=psp --enable-plugins --default-dynamic
 +
If everything is installed correctly, ScummVM will inform you as it finds the right components. Finally type
 +
  make
 +
to build.

* You can downgrade your PSP's firmware to 1.50, but doing so can completely break your PSP (a process called "bricking", as afterward your PSP is essentially nothing but a fancy brick). The reason some brick is mainly due to a hardware problem. Some PSP's have a motherboard referred to as TA-082, and any PSP with this motherboard will not allow 1.50 to be run on the PSP, therefore downgrading will irrevocably break such a PSP.

* While it is possible to compress certain game resources to reduce their size, this can (and usually will) cause games (especially animations) to be choppy sometimes, as it requires extra CPU power to decode these files. As such, it is recommended to play games in their original, uncompressed, form whenever possible.

'''Q''': What do I need to run the games?<br/>
 
'''A''': A 1.00 or 1.50 firmware PSP (or an EBOOT loader on firmware 2.00 or higher), and the necessary datafiles for the game you want to play and obviously ScummVM.
 
  
'''Q''': Can I run <Game XXX> with this?<br/>

Yotam Barnoy  (yotambarnoy@gmail.com)

'''Q''': My Monkey Island 1 doesn't have any music, what gives?<br/>
 
'''A''': If your version of Monkey Island came on a CD then it has the music as CD Audio tracks. You need to rip those to MP3/Ogg and copy them to the same directory as the game data files for music to work.
 
 
 
'''Q''': <Game XXX> crashes, or <Feature YYY> doesn't work. Can you fix this?<br/>
 
'''A''': Possibly.<br/>
 
Because of the large amount of games ScummVM supports we obviously haven't played them all start-to-finish on the PSP, so it is possible there are bugs or issues that we are not aware of.<br/>
 
When you encounter such a bug, please use the [http://sourceforge.net/tracker/?group_id=37116&atid=418820 ScummVM bug tracker], and mention all relevant info (i.e. that you're using the PSP version, which ScummVM version it is, if the problem exists in a recent PC SVN version, a detailed description of the problem, and if possible a nearby savegame). This will make it much easier for us to understand, reproduce and hopefully fix the problem.

ScummVM has been ported to the Sony PlayStation Portable.

For more information, including how to install and use ScummVM, see the PlayStation Portable page in the ScummVM user documentation

Image viewer

For your convenience, I've included a simple image viewer in the PSP port. You can view anything you want while playing a game. There are a few simple rules to follow:

  • Images must be of PNG format. If you have images in another format, many graphics utilities will convert them for you.
  • Images must be named psp_image1.png, psp_image2.png etc. This is to make sure there's no possible conflict between image files and game files.
  • Images must be placed in the game directories. When using the image viewer,only the images of the particular game being played will be available for viewing.
  • Don't place any images in the ScummVM directory, or you won't be able to seethe images in the game directories.
  • There's no guarantee that you'll be able to view your image. This is because big images take a lot of memory (more than the size of the image on disk). If there isn't enough memory left to show the image, ScummVM will tell you so. Try to make the image smaller by either shrinking it or reducing the colors to 256 color palette mode.

Developer information

Building from source

To build ScummVM for PSP you need:

(x) = optional

Once you've installed these libraries (read their README.PSP for instructions), create a subdirectory in your ScummVM folder called 'builds/psp'. Then, in this folder, type

   ../../configure --host=psp --enable-plugins --default-dynamic 

If everything is installed correctly, ScummVM will inform you as it finds the right components. Finally type

  make 

to build.
