OZvm V1.1 - 1st February 2013
- Install and run any released ROM from Cambridge Computer (UK and foreign versions) from menu.
All ROM's (except Icelandic) as they were released by Cambridge Computer throughout 1987 - 1990, are now bundled with the emulator, easily selectable from dropdown menu. - Double screen size
On desktops with high resolution, a 640x64 pixel screen of the Cambridge Z88 becomes quite small, so allow to magnify the Z88 screen as double size and experience the pixels details.. - Mac OS X support
Previous releases were not working very well on Mac OS X. Graphical user interface has been optimized so single-button mouse on Mac can use to the Slots (to insert/remove cards). Mac application look and feel also done. Colours optimized to look well on Mac. - Improved Z80 CPU hardware emulation
RST 38H & RST 66H couldn't be marked with breakpoints. Interrupt blocking (IFF1 high) were not correctly implemented. Manipulate I and R registers from debug command line. NMI were not implemented properly. Stabilized 4Mb memory segmentation implementation (protect against Array out-of-bounds exceptions). - Improved Blink emulation
COM.RESTIM implemented. Don't emit KEY interrupt when key is released. Improved hard/soft reset emulation. F5 key or stop command now works when emulated Z88 is in COMA state. - User guide and debug command line help migrated to wiki
For more flexible maintainance, all previous help and debug command line reference has been moved to wiki pages. Access help from user interface will open a browser and load appropriate page on the wiki. - Execute debug command scripts when a breakpoint is encountered
Useful utility for integrating Z88 application compilation builds with the host desktop.
- New breakpoint architecture
Breakpoints now live outside the memory model which allows them to be active even though memory is reloaded with other contents. - Click release notes to download.
