About the backend/port
This is the readme for the offficial GP2X ScummVM backend (also known as the GP2X port).
Fully supported official releases of the GP2X ScummVM backend (ScummVM for the GP2X) are made in line with main official releases and are avalalble from the ScummVM downloads page.
This build was tested with firmware 2.1.0 for reference.
Please refer to the GP2X ScummVM forum, WiKi and my own ScummVM page for the latest information on the port.

Game compatibility
For information on the compatability of a specific game please refer to the GP2X compatability section of the ScummVM WiKi.
Please note the version and date of the ScummVM build you are running when reviewing the above list.

Included engines
Just because an engine is included does not mean any/all of its games are supported. Please check game compatability for more infomation.

- Scumm - (All games supported by ScummVM should work to some extent, using the hardware scalar if needed)
- Simon - (Simon the Sorcerer one and two).
- Saga - (Inherit the Earth)
- Sky - (Beneath a Steel Sky)
- Sword - (Broken Sword 1) - This engine uses the hardware scalar to downsize the graphics to fix on the GP2X. It is NOT very nice to look at.
- Sword2 - (Broken Sword 2) - This engine uses the hardware scalar to downsize the graphics to fix on the GP2X. It is NOT very nice to look at.
- Gob - (Goblins one)
- Queen - (Flight of the Amazon Queen)
- Kyra - (The Legend of Kyrandia)

All other game engines are disabled in this release.

Supported audio options
Raw audio.
MP3 audio.
OGG Vorbis audio.
FLAC audio is currently unsupported.
For best results use uncompressed audio in games.

Supported cut-scene options
No cut scene compression options are supported in this release.
Compressed video support will be added to future releases as soon as it is stable.

Recent changes
Refined audio hacks to reduce audio delay a little more.
Enabled hardware scalar code.
Now built using SDL 1.2.9 for the parts of the port that use SDL (some parts now hit the hardware directly).
Enabled new launcher - (Ensure modern.zip and modern.ini are in the same folder as the executable).
Aspect Ratio Correction can now be disabled ‘per game’. When adding a game you can find this option on the GFX tab.
Note: This will cause the game to run with a black border at the bottom as it will be rendered to a 320*200 frame.

How to save
NOTE: Everything is saved to the SD card, saves are stored in the saves folder under your main ScummVM executable unless you set another save location.
The configiration file for ScummVM (.scummvmrc) is stored in the same place as the ScummVM executable.
The save process below is for SCUMM engine games but the principle is the same for all.
In Game.
1. Right Trigger
2. Select SAVE with B
3. Select a position with B
4. Right trigger puts ? in the name box for some text.
5. Press B to save
Basically the emulated keys you can use are equivelent to the values buttons are mapped to,
I have a virtual keyboard to add in at some point ;-)

Controller mappings
Mouse emulation:
Stick: Move Pointer
Stick Click: ‘light’ Left Click
B: Left click
X: Right click
Keyboard emulation:
Start: Return
Select: Escape
Y: Space Bar (Pause)
Right Trigger: Game Menu (Save, Load, Quit etc.)
Volume Buttons: Increase and Decrease volume (5% per press)
Fancy button combos:
NOTE: To use button combos press and hold the Left Trigger then...
Y: Toggle "zoom" mode - Try it in larger games like Broken Sword.
Volume Buttons: Increase and Decrease subtitle speed (In SCUMM games)
Right Trigger: 0 (For skipping the copy protection in Monkey Island 2)
Select: Exit ScummVM completely (and gracefully)

Know issues
Thanks to feedback from teh GP2X community most (all I hope) show-stopping bugs should have been worked out for this release.
There exists a possible random crash (well SegFault). I have had this happen twice and have not tracked down the cause.
It happens very infrequently, both times it was in the DOTT CD intro.
Saving often is never a bad idea anyhow.

Major TODO's
This is a official point release (0.9.1) - To look at the TODO list for the port review this document in any SVN builds.

Additional resources/links
Note: When providing feedback, requests, forum posts, bug reports or anything like that always include a mention of the version of ScummVM you are using (the build version, date and time can be seen in the main game launcher window).
