1 July 2010 - SJK
New for this release:
* Added BeeThoven emulation. The Microbee BeeThoven peripheral is based on a
General Instruments AY-3-8910 Programmable Sound Generator
* Added BeeTalker emulation. The Microbee BeeTalker peripheral is based on a
General Instruments SP0256-AL2 speech synthesiser chip.
* Added --parallel-port option to connect addon parallel port peripherals.
* Added --sdl-putenv option to allow SDL
environment variables to be set.
This can be used to change the behaviour of SDL
. The variables supported
depends on the SDL
version and the SDL
documentation should be consulted.
* Added the current SDL-1.2.14 DLL
to the Windows distribution packages.
* Improvements to speaker sound synchronising with the Z80
when using the
BeeThoven or BeeTalker peripheral.
* Changes to the printer port, this can now be set to peripheral devices. A
printer (to file) is now just another peripheral that can be connected.
video support handling has changed on Windows systems when
SDL-1.2.14 or later is detected. As SDL
has fixed some OpenGL
that release some of the existing work arounds are now bypassed at run
time. Older SDL
versions should operate as before. Improvements on
Windows systems may be noticeable.
* Added some SDL
environment variables examples in ubee512rc.sample.
* Added --parallel-port=joystick to games.ini.sample.
* Added the required SP0256 ROM alias entry to roms.alias.sample.
* Changes to the volume coding required the default volume percentage to be
increased from 15% to 45% to compensate.
* Build platform for Linux binaries upgraded to Ubuntu
10.04 Lucid Lynx.
* Lock keys up/down bug is now fixed in SDL-1.2.14 when the SDL
variable SDL_DISABLE_LOCK_KEYS is set to "1". This is done internally by
the emulator when SDL-1.2.14 is detected. Games such as Micro Defender
should now work.
* SDL-1.2.14 has some issues with false mouse movement events when the mouse
cursor is disabled. This has been worked around, this has also fixed some
existing issues with the mouse cursor in full screen mode. Full screen
mode can now start-up with the mouse cursor disabled.
* On Unix builds the time in milliseconds was not being calculated correctly
as a 64 bit value.
* The mouse double click detection had the wrong size timer variable which
had the potential to cause problems.
