Microbee emulator

14 December 2007 - SJK

----------------------

uBee512 v2.2.0

 

New for this release:

* Old colour circuit emulation added and is now the default for colour models except for Premium and 256TC models. Some values still require further investigation to be emulated fully.

* Added emulator functions that allow Z80 programs to have access to some emulator control and host file system functions.

* CP/M program tools added:

- CP/M to host (cpm2host) and a host to CP/M (host2cpm) file copying program. These can be used for transferring files between the host and CP/M disk images.

- A host directory listing program (hostdir).

- Emulation control (exitemu and reset) programs, allowing the emulator to exit or reset from within the emulator under a CP/M system command.

* Revised Premium/256TC model colours to be more inline with the standard CGA colours and hopefully a closer match to the Premium colours.

* Disk images can be made write protected by adding a trailing underscore character to the image name.

* Added a --hwflash option for Premium (alpha+) models. Only the 256TC and upgraded Premium disk models have hardware flashing enabled by default.

* Added documentation on how to create disk images from Microbee disks.

* No loading of the fallback boot disk if emulating a machine of less than 128K memory.

* Changes so that parallel printer still operates even if no --print options are specified.

* Added 'ubee512_ver.id' file to home account to allow later versions to upgrade all the required account files for Unix systems.

 

Fixed:

* The DS80 'DSK' format did not work. This format has now been fixed and tested.

* Mouse button click causing mbox to be brought into context and a button pressed/released caused undesired screen size change actions fixed.

* Changed all 128, 64, and 56K disk models to default to --piob7=PUP as tbasicc.com failed to work with --piob7=vsync.

Use Xbox 360 to Fully Troubleshoot

Your HD DVDs

 

With the enhanced content and extensive interactivity of HD DVD comes the increased need for an efficient way to troubleshoot coding. The Xbox 360 HD DVD Emulator offers a reliable and economical way of identifying bugs, to help ensure your titles ship error-free.

 

See the XBox 360 HD DVD Emulator Data Sheet. (PDF | 193 KB)

 

The Xbox 360 HD DVD Emulator is as easy to set up as it is to use. Gone are the days of trial-and-error testing, thus reducing the costs associated with the HD DVD media. With Xbox 360 HD DVD Emulator, a simple connection from an Xbox 360 console to your Windows PC is all it takes.

 

Sessions using the Xbox 360 HD DVD Emulator are designed to be used at all phases within your workflow so that you can test at various stages without the hassle. You even have a choice of how to run your session: directly from a network storage share, from a USB drive connected directly to the Xbox 360 console, or from a disc in the Xbox 360 HD DVD player. Different settings within your session allow you to test your titles in different trust modes (FullTrust for AACS-protected titles, or Restricted for non-AACS-protected titles), as well as in different development modes (Strict, forces a stricter interpretation of the HD DVD specifications, and Retail, which tolerates minor title deviations from the HD DVD specifications).

 

When connected to your Windows PC, every emulation session produces a comprehensive log, which you can observe in real time or export to a flat file. You can even filter the types of entries in the log to look for specific types of error conditions.
