= Installation =
=== Installation ===
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:
- Copy the relevant game datafiles to your memory stick (location doesn't matter).
<pre>MAC Address: (Your PSP's specific MAC address)
- Install ScummVM like any other homebrew.
System software version: (Your PSP's firmware version)
- Run ScummVM and use the launcher to add games and run them.
Nickname: (The nickname you put onto PSP)</pre>
- Press Start to return to the launcher and play another game.


=== Controls ===

== Installing onto Memorystick ==
- Images must be of PNG format. If you have images in another format, many
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).  
  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 see
  the 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.


=== Firmware 1.00/1.50 CF - No Exploit ===
=== Image Viewer Controls: ===
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 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.
Left/Right              - previous/next image (e.g. go from psp_image1.png to psp_image2.png)
Up/down                - zoom in/out
Analog                  - move around the image
Triggers, Start:        - exit image viewer


=== Firmware 1.50/1.50 CF - kxploit ===
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.
=== 1st Person Game Mode (Can be ignored by most users) ===
This is a special mode built for 1st person games like Lands of Lore. If you don't have these games you can
safely ignore this mode. To enter or leave this mode, use the combo:


=== Firmware 2.00/2.01/2.50/2.60/2.70/2.71/2.80 - Eloader ===
Right Trigger + Left Trigger + Square
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:
Some buttons have been switched around to make these games more playable:
Square                  - Is the modifier key instead of Right Trigger.
Left/Right Trigger      - Strafe left/right
D-Pad Left/Right        - Turn left/right
Square + D-Pad          - F1/F2/F3/F4
Square + Select        - Image Viewer
Square + Start          - Esc (shows game menu)


# Crash your PSP. If this should happen, restart your PSP and try again.
# 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 ===
=== Notes ===
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.
- Notice that you can switch between games! This is much faster than quitting
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.
  and having to start ScummVM all over again. Go to the global menu and choose 'Return To Launcher'.
  (Some games may not have the Return To Launcher option available yet.)


=== Firmware 1.51/1.52/2.81/3.00/3.01/3.02/3.10/3.11/3.30/3.40 ===
- The PSP version of ScummVM uses the Media Engine to accelerate decoding of MP3 files. This means
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.
  that if you have the choice of compressing using Ogg files or MP3 files, choose MP3 -- the game
  will generally run faster.


== Notes ==
- Plugin files are NOT interchangeable between ScummVM versions! You must copy ALL the
* 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.
  plugin files that come with every version of ScummVM. They sit in the /plugin
  subdirectory. If you get a crash upon startup, try deleting all the existing
  plugin files in the plugin directory and copying the new ones over again.

=== Frequently Asked Questions ===
 
Q:  Scummvm crashes upon starting up!
A:  See the first note above.
 
Q:  Pressing select doesn't make the virtual keyboard show up on screen!
A:  You need to make sure that the kbd.zip file is in the same directory as the ScummVM executable.
 
Q:  What do I need to run the games?
A:  A PSP that can run homebrew and the necessary datafiles for the game you want to play.
 
Q:  Can I run game X with this?
A:  You can find the list of supported games on the compatibility page
    at http://www.scummvm.org
    Note that ScummVM is NOT an emulator. The supported games engines have been painstakingly rewritten.
    It's not easy to add support for a game you want that currently isn't supported.
 
Q:  My Monkey Island 1 doesn't have any music, what gives?
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 (MP3 is preferred), naming them track1.mp3 track2.mp3
    etc. and copy them to the same directory as the game datafiles for music to work.
 
Q:  Game X crashes, or feature Y doesn't work. Can you fix this?
A:  Possibly.
    Because of the large amount of games ScummVM supports we obviously haven't
    played them all start-to-finish on the PSP, so it's possible there
    are bugs or issues that we're not aware of.
    When you encounter such a bug, please use the "Bug Tracker" you find linked
    on the ScummVM website, 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 version, a detailed description of the problem,
    and if at all possible a nearby savegame. This will make it much easier
    for us to reproduce (and hopefully fix) the problem.
 
=== Building the source code ===
 
To build ScummVM for PSP you need:
 
- ScummVM source code (svn co https://scummvm.svn.sourceforge.net/svnroot/scummvm/scummvm/trunk)
 
- PSP toolchain (svn co svn://svn.pspdev.org/psp/trunk/psptoolchain)
 
- 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.
 
- zlib      (svn co svn://svn.pspdev.org/psp/trunk/zlib)
 
- libPNG    (svn co svn://svn.pspdev.org/psp/trunk/libpng)
 
- libmad(*) (svn co svn://svn.pspdev.org/psp/trunk/libmad)
 
- libTremor(*) (svn co svn://svn.pspdev.org/psp/trunk/libTremor)
 
(*) = 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.
