From: Krister Walfridsson
Subject: [SDL] src/joystick/bsd/SDL_sysjoystick.c patch
The *BSD USB HID joystick code has two serious bugs:
1. If a joystick reports unhandled hid_input usage (for example HUG_RZ or
HUG_DIAL), then the last handled value will be overwritten with an
arbitrary value. (Fixed in the patch below by adding a default case.)
2. The current code does only handle logical coordinates in the range 0-255,
while a big part of available joysticks report -128 - 127. (This is solved
in the patch below by first center the range around 0, and then stretch
it to the correct range.)

This should always be called before you exit\&. For the sake of simplicity you can set \fBSDL_Quit\fP as your \fBatexit\fP call, like: .PP .nf \f(CWSDL_Init(SDL_INIT_VIDEO|SDL_INIT_AUDIO); atexit(SDL_Quit); \&. \&.\fR .fi .PP .PP .RS \fBNote: .PP While using \fBatexit\fP maybe be fine for small programs, more advanced users should shut down SDL in their own cleanup code\&.
