All:
Audio rate conversion is only implemented by multiplying or dividing
by a power of two. This is a side-effect of the requirement that the
raw audio buffer size be a power of two, and can hopefully be fixed.
This means 8 KHz audio converted to 22 KHz ends up being 16 KHz. :-/
Bugs are now managed in the SDL bug tracker, here:

When the implementation is writing directly to video memory the mouse
cursor doesn't work properly. Applications which do this should use
their own mouse cursor and call SDL_ShowCursor(0) to hide the system
cursor.
http://bugzilla.libsdl.org/

Linux:
Wide UNICODE character input (Kanji, etc.) is not yet supported.
It requires handling of keyboard mapping events and using the XIM
input translation extension. I will implement it as requested.
Latin-1 keyboard input works fine.
(UPDATE 04/06/2004: this bug is now fixed)
You may report bugs there, and search to see if a given issue has already
been reported, discussed, and maybe even fixed.

The keyboard modifiers are not set to the correct state on startup.

The AAlib, GGI, and SVGAlib video drivers are not heavily tested.

Win32:
The MCI driver can't tell if the CD-ROM drive is paused or stopped.
You may also find help at the SDL mailing list. Subscription information:

The SDL_INIT_EVENTTHREAD flag is not supported on Win32
(Idea: create a separate DirectInput polling thread)
The main purpose of this flag is for smooth cursor motion in
fullscreen environments.

Wide UNICODE character input (Kanji, etc.) is not yet supported.
This requires the ToUnicode() API which is only implemented on
Windows NT/2000, not on Windows 95/98.
Latin-1 keyboard input works fine.
Bug reports are welcome here, but we really appreciate if you use Bugzilla, as
bugs discussed on the mailing list may be forgotten or missed.

Joysticks are only supported under the Win32 MultiMedia API,
DirectInput support is not yet implemented.

BeOS:
BePPC is not supported, apparently not even by Be Inc.

SDL_WM_GrabInput() is not implemented.
Does anyone know how to do this? SDL_WM_GrabInput() is designed
to prevent the user from switching input and mouse focus away from
the SDL application.

Continuous relative mouse motion is not implemented.

Wide UNICODE character input (Kanji, etc.) has not been tested.
Latin-1 keyboard input works fine.

MacOS:
Palette handling isn't implemented in windowed mode yet.

Audio hasn't been extensively tested, in particular the locking
isn't implemented and mixer routines may not call malloc() or free()
because they are called at interrupt time.

SDL_WM_GrabInput() is not implemented.
Does anyone know how to do this? SDL_WM_GrabInput() is designed
to prevent the user from switching input and mouse focus away from
the SDL application.

Continuous relative mouse motion is not implemented.

SDL_AddTimer() and SDL_RemoveTimer() haven't been implemented yet.

Not all of the keys are properly recognized on the keyboard.

Mac OS X:
Depth switching for windowed mode isn't implemented yet.

Palette handling isn't implemented in windowed mode yet.

Command-line arguments dialog is not implemented yet.

Fullscreen drawing has some artifacts.

Fullscreen OpenGL for the software renderer is broken.

Some OpenGL parameters are not accounted for, for example color bits customization.

Continuous mouse motion perhaps is not as smooth as it should be.

SDL_WM_GrabInput() is implemented, but it "freezes" the hardware
cursor in the center of the window/screen. Also, mouse moved events
are not generated, and the keyboard cannot be grabbed.

Mac OS X seems to have a broken pthread_cancel() implementation.
Actually, it just only has one cancellation point defined.
http://lists.apple.com/archives/darwin-development/2004/Jun/24/killingapthread.001.txt

FreeBSD:
pthread_cancel() isn't supported by FreeBSD 3.X, so threads don't
work on versions of FreeBSD earlier than 4.0.

The CD-ROM handling doesn't work completely.

Wide UNICODE character input (Kanji, etc.) is not yet supported.
It requires handling of keyboard mapping events and using the XIM
input translation extension. I will implement it as requested.
Latin-1 keyboard input works fine.
(UPDATE 04/06/2004: this bug is now fixed but needs testing)

Solaris:
The joystick functions are not implemented yet.

IRIX:

input translation extension. I will implement it as requested.

(UPDATE 04/06/2004: this bug is now fixed but needs testing)

The keyboard modifiers are not set to the correct state on startup.

EPOC:
Only Crystal version of Epoc/SymbianOS is currently supported.

SDL is implemented in static library only. SDL uses static/global
variables and that is not allowed in EPOC dll libraries.

Sound is not yet supported.

Joystick, OpenGL and cdrom is not supported (think about cdrom in a cell phone:-).

No console output screen. Printing to stdout do not have any effect.

QNX:
Fullscreen switch doesn't work (disabled for now).


OpenBSD: -= NOT YET SUPPORTED =-
This is reported to work, but I haven't verified this.

Wide UNICODE character input (Kanji, etc.) is not yet supported.
It requires handling of keyboard mapping events and using the XIM
input translation extension. I will implement it as requested.
Latin-1 keyboard input works fine.
(UPDATE 04/06/2004: this bug is now fixed but needs testing)

OSF/Tru64: -= NOT YET SUPPORTED =-
The audio functions are not implemented yet.

Joysticks and CD-ROM functions are not implemented yet.

input translation extension. I will implement it as requested.
Latin-1 keyboard input works fine.

AIX: -= NOT YET SUPPORTED =-
This port has only been tested with AIX 4.3.3

The OpenGL support doesn't work yet.

The joystick subsystem isn't implemented yet.

Endian detection doesn't work yet - needs a unique CPP symbol.

Wide UNICODE character input (Kanji, etc.) is not yet supported.
It requires handling of keyboard mapping events and using the XIM
input translation extension. I will implement it as requested.
Latin-1 keyboard input works fine.
(UPDATE 04/06/2004: this bug is now fixed but needs testing)

The AIX port was done by Carsten.Griwodz@KOM.tu-darmstadt.de
