macemu/BasiliskII/ChangeLog

V1.0 (snapshot) - <date>
 - fixed support for volumes larger than 4 GB

 - JIT: integrated dynamic translator for Linux/x86 and FreeBSD/x86
 - JIT: ported backend to support Linux/x86_64 (AMD64 and EM64T platforms)

 - JIT: improve detection of newer CPUs based on the P4 core but
   fallback to a safe default, if necessary
 - Unix: moved minimum autoconf support to 2.52+
 - Unix: add large file support for 2+ GB hard disk images
 - Unix: cleaned up pthread attributes [Brian Johnson]
 - Unix: fixed floppy problems under Linux
 - Unix: implemented "ignoresegv" feature on Linux/x86, Linux/ppc, Darwin/ppc
 - Unix: serial port baud rates are now set correctly

   to programs by using a '|' followed by a command line as the modem or
   printer port setting (instead of a device name like '/dev/ttyS0')
   [Brian Johnson]
 - Unix: the option "--config FILE" tells B2 to use a different config file
 - Unix: new prefs options "dsp" and "mixer" to set the OSS device names
   instead of the hardcoded '/dev/dsp' and '/dev/mixer'
 - Unix: new ether prefs option 'tun' to use a TUN/TAP interface. The
   configure script used can be overriden with "etherconfig"

V1.0 (snapshot) - 15.Jan.2002
 - added support for on-the-fly video resolution and depth switching, and
   gamma tables
 - fsave/frestore emulation under AmigaOS and NetBSD/m68k always behaves like
   a 68882/68040 FPU, eliminating the need for 68060 FPU patches
 - added support for platform-independant mutexes, used by adb.cpp for
   thread-safe mouse handling
 - the TIME_OFFSET constant has been replaced by a (portable) function
   TimeToMacTime(); file dates in ExtFS should now be correct
 - ADBInterrupt() is no longer called from the 60Hz interrupt but has its own
   interrupt flag, potentially increasing the smoothness of mouse movement
 - ether.cpp: implemented relatively platform-independant "AppleTalk over UDP"
   mode that doesn't require any special kernel modules or network drivers but
   can only interconnect instances of Basilisk II; this is enabled by setting
   "udptunnel" to true
 - Unix: windowed display mode supports different resolutions and color depths,
   which can be switched on-the-fly
 - Unix: Ctrl-F5 grabs mouse in windowed mode (enhanced compatibility with
   games like flight simulators)
 - Unix: X11 events are handled as soon as they arrive, outside of the 60Hz
   video refresh raster
 - Unix: audio sample rate, bit depth and channel count are adjustable in the
   MacOS "Sound" control panel

 - AmigaOS/Unix: it's possible to specify preferences items on the command line
 - BeOS: implemented the "powerrom_cpu" CPU engine for BeOS/PPC that uses the
   680x0 emulator contained in an Apple PowerMac ROM to run Basilisk II (ca.
   4x speed improvement); when running on a BeBox, a PCI PowerMac ROM image is
   needed to use this (the path name of the ROM file can be set with the
   preferences item "powerrom", default is "PowerROM")

   turned off
 - medium removal is allowed in CDROMExit()
