Subject: [SDL] Linux joystick patch
I recently got myself a PS2 -> USB converter (a super joybox 5). It
accepts 4 PSX/PS2 controllers. It's implemented as a HID, which is nice
because it doesn't require its own driver, but the problem is that it's
implemented as a *single* HID -- that is, it shows up as a single
joystick with 19 axes, 4 hats, and 48 buttons. This poses a problem for a
number of apps which use SDL (stella, fce ultra, zsnes, to name a few) and
see only a single (physical) joystick even though there are really 4
(logical) joysticks. There are a number of these types of devices on the
market, and I've seen others post messages (in the zsnes forum, for
example) with the same problem, so I came up with what I think is a pretty
generic solution.
I patched src/joystick/linux/SDL_sysjoystic.c to include support for
logical joysticks; basically, it's a static array and supporting functions
that map a single physical joystick to multiple logical joysticks. The
attached patch has the new code. It's wrapped inside #ifndef
statements so that you can get the old behavior if you want.

This is the porting of 1.2.0 version of SDL (the latest stable one) to AmigaOS/68k. All the bugs known of the past version have been corrected. And I've added all the new SDL features. This version of SDL needs Cybergraphx V3 (r69+) or CyberGraphX V4 and AHI v3+. Probably it works also with P96 or CGXAga, but it's untested. This version is available as linked library for SAS/C and GCC, only 68k this time, a powerup (ppcemu compatible) and a morphos version will be ready quite soon (i hope). Implemented: - 8/16/24/32bit video modes, both fullscreen and windowed. - Hardware surfaces. - CGX blitting acceleration. - CGX colorkey blitting acceleration. - AHI audio (8/16 bit, with any audio format), always uses unit 0 for now. - Thread support (maybe not 100% compatible with other implementations) - Semaphores - Window resizing and backdrop windows (NEW) - Joystick/Joypad support. To do: - CDRom audio playing support - OpenGL (A guy was working on it but I've lost his tracks :( ) The SAS/C library is distributed with debug info attached, to strip debug info simply add STRIPDEBUG argument to the linker. NOTE: SDL includes debug output using kprintf, to disable it add to your project a function like this: void kprintf(char *a,...) { } Otherwise you can redirect the debug to a console window with sushi, sashimi or similar tools (the default output is the internal serial port).
