-This is the porting of 1.2.0 version of SDL (the latest stable one)
-to AmigaOS/68k.
+The AmigaOS code has been removed from SDL, since it had been broken for a
+ long time and had a few bits of fairly invasive code #ifdef'd into the
+ SDL core.
 
-All the bugs known of the past version have been corrected. And I've
-added all the new SDL features.
+However, there is an OS4 version of SDL here:
+   http://www.rcdrummond.net/amiga/index.html
 
-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.
+And a MorphOS version here:
+   http://www.lehtoranta.net/powersdl/
 
-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).
+--ryan.
 
-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).
