Date: Sun, 18 Apr 2004 16:09:53 -0400 (EDT) From: David MacCormack 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.

Date: Sat, 10 Apr 2004 10:05:46 +0200 From: Christian Walther Subject: [SDL] OpenGL Accumulation Buffer on Mac OS X Is there a reason for not having OpenGL accumulation buffer support in SDL 1.2.7 (and as far as I have checked also in the current CVS) on Mac OS X? Maybe I am doing something wrong, but it seems very easy to add (at least it works for for me in 10.3.3) - just add if ( this->gl_config.accum_red_size + this->gl_config.accum_green_size + this->gl_config.accum_blue_size + this->gl_config.accum_alpha_size > 0) { attr[i++] = NSOpenGLPFAAccumSize; attr[i++] = this->gl_config.accum_red_size + this->gl_config.accum_green_size + this->gl_config.accum_blue_size + this->gl_config.accum_alpha_size; } to QZ_SetupOpenGL() in SDL_QuartzGL.m

ate: Fri, 09 Apr 2004 20:07:10 +0200 From: Hibernatus Subject: [SDL] BUG: changing video mode in opengl + windows In WIN_GL_SetupWindow (SDL12/src/video/wincommon/SDL_wingl.c) you call WIN_GL_ResetWindow when SetPixelFormat fails. WIN_GL_ResetWindow cannot properly work in its current state, because there are several things to update once you've created a new window. At least DirectInput doesn't work anymore here (which is somewhat annoying for the player :). I think you can simply remove that function. Many games don't try to recover from that exception, that's why the newest ATI drivers emulate 16 bpp display in 32 bpp mode so the error never occurs (but the games may run much slower). Having SDL_SetVideoMode return NULL would be better than actually setting the video mode and losing focus, directinput and maybe directsound too. It also made my previous drivers crash (when switching from 32 bpp windowed to 16 bpp fullscreen).

Date: Sat, 24 Apr 2004 15:13:32 +0300 From: "Mike Gorchak" Subject: SDL updates for the QNX6 1. Updated the README.QNX 2. Updated libtool scripts, which are shipped with SDL for QNX6 support. 3. Added some code to support the new QNX 6.3.0, which is in beta now. 4. Added code to detect the hw features, which driver supports. 5. Added hw alpha blits code. 6. Fixed bug when application switches to fullscreen more the 2 times. (afte\ r that window becames always stay on top). 7. Updated a bit README for the tests. 8. Added information about acceleration show in the testalpha.c test. 9. Added small fixes to the testoverlay2.c test. 10. Added alpha and cc+alpha blits benchmarks to the testvidinfo.c test.

Date: Wed, 28 Apr 2004 16:52:41 -0400 From: "Damien A" Subject: testdyngl fix The test program you included in the latest version of SDL crashes on startup in Window (XP). The reason for this is that OpenGL functions on Windows use the __stdcall calling convention, not the C convention. Placing APIENTRY infront of the * operator solves this problem.

Increment version...

Date: Sat, 10 Apr 2004 02:25:33 -0400 From: Glenn Maynard To: sdl@libsdl.org Subject: [SDL] SDL_SetVideoMode() failing and not setting an error (patch) Running an OpenGL SDL application off 1.2.7, at SDL_InitSubSystem(SDL_INIT_VIDEO) time: Warning: Unable to initialize AAlib mouseUsing AAlib driver: Slang driver 1.0 (slang) SDL_SetVideoMode then fails; SDL_GetError() returns "". The installation problem is straightforward: X (the higher priority driver) isn't running, so SDL is falling back on aalib. However, no error is being set when aalib fails to initialize. This also happens with the svgalib driver. SDL_video.c line ~653 sets mode to NULL, since aalib didn't return an OpenGL surface. Line ~711 ("failed setting a video mode") returns NULL. The attached patch sets an error. It's a horrible, useless error message--it should really say eg. "aalib does not support OpenGL"; this should probably be done earlier in the individual drivers, too.
