Date: Sat, 14 Jan 2006 15:16:01 -0500 From: Andrew Fuller Subject: [SDL] [PATCH] ML-8866 PS2->USB converter This converter seems to go by several names -- Super Dual Box, Dual USB Joypad, and who knows what else. Also branded differently with different colour cases, etc. But it seems to all be the same internals. It is a common converter used for StepMania, with several posts Googleable trying to make it work in Linux. I got mine yesterday and wanted to play stepmania, so I went ahead and made a crude patch for libsdl to split this baby into two logical joysticks. A couple notes about the patch: This patch works well for two dance mats hooked up and playing stepmania, however the mapping of the other buttons may be off. I have no joystick which uses all the buttons the converter reports, so I have no way of testing them. The name I used 0925:8866 which is the USB ID, and what SDLjoytest-GL reported is the name, even though lsusb shows Wisegroup, Ltd MP-8866 Dual USB Joypad, and the existing virtual joystick mapping uses the Wisegroup... name. Not sure why the discrepency. I'm not subscribed to this mailing list, so please CC me on any comments to this. -Andrew

 ========================
  Using SDL with PicoGUI
 ========================

- Originally contributed by Micah Dowty <micahjd@users.sourceforge.net>

PicoGUI is a scalable GUI system with a unique architecture, primarily focused
on scalability to various embedded systems. You can find more information
including a FAQ at http://picogui.org

To use the patch:

  1. When compiling, add the "--enable-video-picogui" switch to ./configure

  2. When running your program, ensure that the picogui driver for SDL
     is in use by setting the SDL_VIDEODRIVER environment variable 
     to "picogui".

  3. The program must also be linked to the C client library for PicoGUI
     (libpgui.so). If the program is being compiled with a patched SDL 
     installed this should be done automatically. If you want to use an
     existing binary with PicoGUI, you can set the LD_PRELOAD environment
     variable to the path of your libpgui.so file.

Capabilities:

  So far only basic functionality is provided on true color (linear16/24/32)
  devices. Accessing a memory mapped bitmap, updating the display, and handling
  mouse/keyboard input. This functionality has been tested with several
  applications, including mplayer, Xine, sldroids, and Abuse.

TODO list:

  - YUV overlays will be helpful for watching video on set top boxes or other
    embedded devices that have some graphics acceleration hardware

  - Account for rotated bitmap storage in pgserver

  - Support for hiding or changing the cursor

  - The display should be centered when the SDL application is smaller
    than the PicoGUI panel

  - Fullscreen or any other special modes

  - Support for indexed and grayscale modes

  - Probably much more...
