Date: Wed, 23 Jun 2004 17:05:33 -0400 From: Chris Nelson Subject: [SDL] [Patch] WiseGroup MP-8800 / MP-8866 (PS2 Joystick) In the current cvs version, SDL doesn't handle these Playstation2 controller => USB adapters correctly, in linux. It will always assume that the maximum number of joysticks (2 in the case of the MP-8866, 4 in the case of the 8800) are plugged in. This is bad not only because it allows SDL to exaggerate the number of logical joysticks, but primarily because the joystick axes are mapped incorrectly, all over the place, such that the devices are effectively unusable unless you have the maximum number of joysticks plugged in. My changes to src/joystick/linux/SDL_sysjoystick.c build on another's previous work (which was a special case for this very joystick, actually), and fix both of these problems, as well as making the current code a little more general, to allow for others to more easily drop in code for quirky joysticks such as these. I've tested this code under 2.6.7 as well as 2.4.24... Both work as advertised (provided you load the JOYDEV linux code as a module, otherwise they won't work at all, new code or old, but that's another issue entirely). Though this sounds horribly formal, you have my permission to distribute all of my work on this issue under the LGPL. So there.

Wish list for the 1.3 development branch:

 * Use /etc/fb.modes, if available, like GGI does
 * Add mousewheel events (new unified event architecture?)
 * DirectInput joystick support needs to be implemented
 * Be able to enumerate and select available audio and video drivers
 * Fullscreen video mode support for MacOS X
 * Explicit vertical retrace wait (maybe separate from SDL_Flip?)
 * Shaped windows, windows without borders
 * Multiple windows, multiple display support
 * SDL_INIT_EVENTTHREAD on Windows and MacOS?
 * Add a timestamp to events
 * Use RDTSC for timer resolution on x86 hardware
 * Add audio input API
 * Add hardware accelerated scaled blit
 * Add hardware accelerated alpha blits
 * Redesign blitting architecture to allow blit plugins

In the jump from 1.2 to 1.3, we should change the SDL_Rect members to
int and evaluate all the rest of the datatypes.  This is the only place
we should do it though, since the 1.2 series should not break binary
compatibility in this way.

Requests:
 * PCM and CDROM volume control (deprecated, but possible)
