     2
All:
slouken@0
     3
	Audio rate conversion is only implemented by multiplying or dividing
slouken@0
     4
	by a power of two.  This is a side-effect of the requirement that the
slouken@0
     5
	raw audio buffer size be a power of two, and can hopefully be fixed.
slouken@0
     6
	This means 8 KHz audio converted to 22 KHz ends up being 16 KHz. :-/
slouken@0
     7
slouken@0
     8
	When the implementation is writing directly to video memory the mouse
slouken@0
     9
	cursor doesn't work properly.  Applications which do this should use
slouken@0
    10
	their own mouse cursor and call SDL_ShowCursor(0) to hide the system
slouken@0
    11
	cursor.
slouken@0
    12
slouken@0
    13
Linux:
slouken@0
    14
	Wide UNICODE character input (Kanji, etc.) is not yet supported.
slouken@0
    15
	It requires handling of keyboard mapping events and using the XIM
slouken@0
    16
	input translation extension.  I will implement it as requested.
slouken@0
    17
	Latin-1 keyboard input works fine.
slouken@0
    18
slouken@27
    19
	The keyboard modifiers are not set to the correct state on startup.
slouken@27
    20
slouken@0
    21
	The AAlib, GGI, and SVGAlib video drivers are not heavily tested.
slouken@0
    22
slouken@0
    23
Win32:
slouken@0
    24
	The MCI driver can't tell if the CD-ROM drive is paused or stopped.
slouken@0
    25
slouken@0
    26
	The SDL_INIT_EVENTTHREAD flag is not supported on Win32
slouken@0
    27
	(Idea: create a separate DirectInput polling thread)
slouken@0
    28
	The main purpose of this flag is for smooth cursor motion in
slouken@0
    29
	fullscreen environments.
slouken@0
    30
slouken@0
    31
	Wide UNICODE character input (Kanji, etc.) is not yet supported.
slouken@0
    32
	This requires the ToUnicode() API which is only implemented on
slouken@0
    33
	Windows NT/2000, not on Windows 95/98.
slouken@0
    34
	Latin-1 keyboard input works fine.
slouken@0
    35
slouken@0
    36
	Joysticks are only supported under the Win32 MultiMedia API,
slouken@0
    37
	DirectInput support is not yet implemented.
slouken@0
    38
slouken@0
    39
BeOS:
slouken@0
    40
	BePPC is not supported, apparently not even by Be Inc.
slouken@0
    41
slouken@0
    42
	SDL_WM_GrabInput() is not implemented.
slouken@0
    43
	Does anyone know how to do this?  SDL_WM_GrabInput() is designed
slouken@0
    44
	to prevent the user from switching input and mouse focus away from
slouken@0
    45
	the SDL application.
slouken@0
    46
slouken@0
    47
	Continuous relative mouse motion is not implemented.
slouken@0
    48
slouken@0
    49
	Wide UNICODE character input (Kanji, etc.) has not been tested.
slouken@0
    50
	Latin-1 keyboard input works fine.
slouken@0
    51
slouken@0
    52
MacOS:
slouken@0
    53
	Palette handling isn't implemented in windowed mode yet.
slouken@0
    54
slouken@0
    55
	Audio hasn't been extensively tested, in particular the locking
slouken@0
    56
	isn't implemented and mixer routines may not call malloc() or free()
slouken@0
    57
	because they are called at interrupt time.
slouken@0
    58
slouken@0
    59
	SDL_WM_GrabInput() is not implemented.
slouken@0
    60
	Does anyone know how to do this?  SDL_WM_GrabInput() is designed
slouken@0
    61
	to prevent the user from switching input and mouse focus away from
slouken@0
    62
	the SDL application.
slouken@0
    63
slouken@0
    64
	Continuous relative mouse motion is not implemented.
slouken@0
    65
slouken@0
    66
	SDL_AddTimer() and SDL_RemoveTimer() haven't been implemented yet.
slouken@0
    67
slouken@0
    68
	Not all of the keys are properly recognized on the keyboard.
slouken@0
    69
slouken@0
    70
MacOS X:
slouken@47
    71
	Depth switching for windowed mode isn't implemented yet.
slouken@47
    72
	
slouken@0
    73
	Palette handling isn't implemented in windowed mode yet.
slouken@47
    74

    76
slouken@47
    77
	Fullscreen drawing has some artifacts.
slouken@47
    78
	
slouken@47
    79
	Fullscreen OpenGL for the software renderer is broken.
slouken@0
    80
slouken@47
    81
	Some OpenGL parameters are not accounted for, for example color bits customization.
slouken@47
    82
	
slouken@47
    83
	Continuous mouse motion perhaps is not as smooth as it should be.
slouken@0
    84
slouken@47
    85
	SDL_WM_GrabInput() is implemented, but it "freezes" the hardware
slouken@47
    86
	cursor in the center of the window/screen.  Also, mouse moved events
slouken@47
    87
	are not generated, and the keyboard cannot be grabbed.
slouken@0
    88
slouken@0
    89
	MacOS X seems to have a broken pthread_cancel() implementation.
slouken@0
    90
slouken@0
    91
FreeBSD:
slouken@0
    92
	pthread_cancel() isn't supported by FreeBSD 3.X, so threads don't
slouken@0
    93
	work on versions of FreeBSD earlier than 4.0.
slouken@0
    94
slouken@0
    95
	The CD-ROM handling doesn't work completely.

    96

   127
    Only Crystal version of Epoc/SymbianOS is currently supported.
slouken@250
   128
slouken@250
   129
    SDL is implemented in static library only. SDL uses static/global

   131
slouken@250
   132
