-----------------
uBee512 v4.7.0
New for this release:
* Added BeeThoven emulation. The Microbee BeeThoven peripheral is based on a
General Instruments AY-3-8910 Programmable Sound
Generator chip.
* 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.
Changes:
* 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.
*
OpenGL video support handling has changed on Windows systems when
SDL-1.2.14 or later is detected. As
SDL has fixed some
OpenGL bugs in
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.
Fixed:
* Lock keys up/down bug is now fixed in SDL-1.2.14 when the
SDL environment
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.
