------------------
uBee512 v4.0.0
New for this release:
* Added the z80ex Z80 emulator and is now the default.
* Completely overhauled the memory and ports management system, there is no longer any banked memory swapping, this has greatly reduced host CPU time for some Microbee systems and other code.
* Will now compile and work on Mac OS X Intel and PPC models. The PPC's Big Endian architecture has not been fully tested.
* Added full screen, sound, volume+, volume- and tape buttons to OSD menu and removed Cancel.
Changes:
* Recoded various source modules to make use of new Z80 APIs. The new method allows other Z80 emulators to be added.
* Serial, parallel printer, and other PIO interrupts have been improved.
* Changes made to PIO SW serial resulting in better performance.
* The Vertical blanking period has been increased to 15% to produce better sound with z80ex and when MWB v6.30e is used.
* Changed the --version option to also report the Z80 emulator in use.
* Double left button mouse click no longer toggles full screen mode when the OSD has the focus.
* Changes to ubee512rc to include a 'darwin' start-up conditional.
* Changes and additions to roms.alias file.
* Changed games.ini.sample to create the temporary games image in the default disks location.
Fixed:
* Fixed MD5 file matching to keep trying other matching MD5 entries when the file name is not found.
* Fixed segmentation error when creating a '.temp' file and the creation of the file fails for any reason.
* Fixed mouse cursor positioning when switching between full screen and window displays.
* Fixed incorrect disassembly of IX and IY instructions.
* Fixed the standard PC85 model's Shell garbled text problem by presetting some RAM locations. (this is actually a Shell bug)
* z80ex handles maskable interrupts better and has fixed some issues.
* z80ex fixes some instructions and passes all the 'zexall.com' Z80 exerciser program tests. (use -x500 to increase testing speed)
* GUI status line is now updated after an OSD console command is entered.
