PlayStation Portable

Based on README.PSP and jak66's forum post.

Installation

First, look up the version/firmware or your PSP. You can do this by going to system settings and then system information.

You will get 3 lines:

MAC Address: (Your PSP's specific MAC address)
Nickname: (The nickname you put onto PSP)
System software version: (Your PSP's firmware version)

There are 12 different official firmware versions:

• 1.00
• 1.50
• 1.51
• 1.52
• 2.00
• 2.01
• 2.50
• 2.60
• 2.70
• 2.71
• 2.80
• 2.81

There are also two unofficial versions:

• 1.50 CF (= 1.5 Custom Firmware)
• 2.71 SE-A

Firmware 1.00

Put the single eboot file (eboot.pbp) in a folder scummvm-psp on your memory stick in the game folder, which is in the psp folder (so ms0:/psp/game/scummvm-psp/eboot.pbp, where ms0:/ is your memory stick root) then you go into the __SCE__scummvm-psp folder and copy all the files EXCEPT the eboot.pbp into the folder that you placed the single eboot.pbp (so ms0:/psp/game/scummvm-psp/) run from XMB (cross media bar, which is what you see when you turn the PSP on).

Firmware 1.50/1.50 CF

Copy the folders __SCE__scummvm-psp and %__SCE__scummvm-psp into the game folder in the psp folder on your memory stick (so ms0:/psp/game/%__SCE__scummvm-psp/ and ms0:/psp/game/__SCE__scummvm-psp/). Run from XMB. 1.50 CF can also follow 1.00 instructions, (if you would prefer only having one folder).

Firmware 1.51/1.52/2.80/2.81

At the time of this writing, one cannot use any homebrew software (including ScummVM) on these firmwares (except for TIFF homebrew on 2.80). 1.51 and 1.52, however, can be upgraded to 2.0-2.71, allowing the use of homebrew software.

Firmware 2.00/2.01/2.50/2.60/2.70/2.71

Follow the instructions for firmware 1.0 until (but not including) the point where you are supposed to run XMB. Don't actually try to run XMB, as it wont work. You now need to download eLoader (0.99 was the latest eloader version when this text was written). Use the exe if you can, but there should be a readme for installation. Once installed go to "photo viewer" then press start when on the folder called "eloader 099" (or something similar). This will load eMenu. Now just locate scummvm-psp and press X. For firmware 2.71, you also have the option to use HenC.

Firmware 2.71 SE-A

Follow the instructions for firmware 1.0, except that you place the scummvm-psp folder in the game150 folder rather than the game folder (so ms0:/psp/game150/scummvm-psp/). Now run from XMB.

Notes

• You can degrade 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.

Notes

• 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.

• Sleep/Suspend mode currently isn't supported, so don't use it when running ScummVM.

Frequently Asked Questions

Q: What do I need to run the games?
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?
A: See the list of supported games.

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 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?
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 is possible there are bugs or issues that we are not aware of.
When you encounter such a bug, please use the 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.
