+------------------------------------------------------------------------
+About the backend/port
+
+This is the readme for the offficial GP2X WIZ ScummVM backend (also known as
+the GP2X WIZ port).
+
+This is an SVN test release of ScummVM for the GP2X WIZ, it would be
+appreciated if this SVN test distribution was not mirrored and that
+people be directed to http://scummvm.distant-earth.com/ instead for
+updated SVN builds.
+
+Full supported official releases of the GP2X WIZ ScummVM backend are made in
+line with main official releases and are avalalble from the ScummVM
+downloads page <http://www.scummvm.org/downloads.php>.
+
+This build is in an active state of development and as such no
+"expected" behavior can be guaranteed ;).
+
+SVN builds are quickly tested with firmware 1.0.0 for reference.
+
+Please refer to the GP2X/GP2X WIZ ScummVM forum
+<http://forums.scummvm.org/viewforum.php?f=14> and WiKi
+<http://wiki.scummvm.org/index.php/GP2X> 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
+<http://wiki.scummvm.org/index.php/GP2X#Compatibility_List>.
+
+Please note the version and date of the ScummVM build you are running
+when reviewing the above list.
+
+------------------------------------------------------------------------
+Supported audio options
+
+Raw audio.
+MP3 audio.
+OGG Vorbis audio.
+
+FLAC audio is currently unsupported.
+
+For best results use uncompressed audio in games.
+
+------------------------------------------------------------------------
+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. Menu Button
+2. Select SAVE with B
+3. Select a position with B
+4. Right trigger puts 0 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,
+
+------------------------------------------------------------------------
+Controller mappings
+
+Touch screen:
+Touch: Move Pointer and Left click
+
+Mouse emulation:
+
+dPad: Move Pointer
+B: Left click
+X: Right click
+
+Keyboard emulation:
+
+Right Trigger: Return
+Select: Escape
+Y: Space Bar (Pause)
+Menu: 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...
+
+Right Trigger: 0 (For skipping the copy protection in Monkey Island 2)
+Menu: Bring up the Global main menu for ScummVM
+Select: Exit ScummVM completely (and gracefully)
+
+------------------------------------------------------------------------
+Know issues
+
+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.
+
