Front End (Mac only)

A host of bug fixes and new additions have been made to EMUlaunch 1.5.1. Most noticeably, EMUlaunch now supports screenshots created by MAME OS X. By default, EMUlaunch looks for the nameoftherom.png inside of the user selected screenshots folder. Now if it does not find it it will now also check ~/Library/Application Support/MAME OS X/Screenshots/romname/0000.png. Several bug fixes and changes to the layout preference screen have also been made.

 

* Support for screenshots created by MAME OS X

* Improved Layout Preference Screen. User can now directly enter parameters to affect the layout of the main screen.

* Added user preference for font sizes

* Added ability to hide black background bevel

* Fixed bug for new users not getting the default layout in the preference screen.

* Fixed bug with reflection on main image being cut off on large images.

* Smooth scaling of button images in the EMUlaunch Dock

* Fonts have been changed throughout the application to use the system font “Lucida Grande”

* Screenshot image now positions itself to the bottom of its container. The reflection now touches the bottom of the image in all cases

TG16 / PCE emulator

2007/12/25 1.31 released

- The DMA reading processing part of CD-ROM was brought close to the movement of a real machine. "Cobra II Densetsu no Otoko", "Lodoss Tou Senki", and "Kagami no Kuni no Legend" came to operate.

- "Use System Memory" was added to "Setting->Screen" menu. Use the favor a sharp image (the burr stands out a little).

- The fade out processing of CDDA (CD sound source) was brought close to a real machine. In "Downtown Nekketsu Koushinkyoku", the problem of the voice was solved.

- With "Option" button of the start window, the window mode start or the full-screen mode start can be set, too.

- Additionally, a detailed part has been improved and corrected.

PC emulator

Changes in 2.3.6 (December 24, 2007):

 

Brief summary :

 

+ More than 25% emulation speedup vs Bochs 2.3.5 release!

 

- Thanks to Darek Mihocka (http://www.emulators.com)

for providing patches and ideas that made the

speedup possible!

 

+ Up to 40% speedup vs Bochs 2.3.5 release with trace cache optimization!

 

- Lots of bugfixes in CPU emulation

- Bochs benchmarking support

- Added emulation of Intel SSE4.2 instruction set

 

Detailed change log :

 

CPU

- Added emulation of SSE4.2 instruction set, to enable use --enable-sse=4 --enable-sse-extension configure options to enable POPCNT instruction only use configure option --enable-popcnt

- Implemented MTRR emulation, to enable use --enable-mtrr configure option. MTRRs is enabled by default when cpu-level >= 6.

- Implemented experimental MONITOR/MWAIT support including optimized MWAIT CPU state and hardware monitoring of physical address range, to enable use --enable-monitor-mwait configure option.

- Removed hostasm optimizations, after Bochs rebenchmarking it was found that the feature bringing no speedup or even sometimes slows down emulation!

- Merged trace cache optimization patch, the trace cache optimization is enabled by default when configure with --enable-all-optimizations option, to disable trace cache optimization configure with --disable-trace-cache

- Many minor bugfixes in CPU emulation (both ia32 and x86-64)

- Updated CPU instrumentation callbacks

 

Bochs Internal Debugger and Disassembler

- Many fixes in Bochs internal debugger and disassembler, some debugger interfaces significantly changed due transition to the param tree architecture

- Added support for restoring of the CPU state from external file directly from Bochs debugger

 

Configure and compile

- Renamed configure option --enable-4meg-pages to --enable-large-pages. The option enables page size extensions (PSE) which refers to 2M pages as well.

- Removed --enable-save-restore configure option, save/restore feature changed to be one of the basic Bochs features and compiled by default for all configurations.

- Added new Bochs benchmark mode. To run Bochs in benchmark mode execute it with new command line option 'bochs -benchmark time'. The emulation will be automatically stopped after 'time' millions of emulation cycles executed.

- Another very useful option for benchmarking of Bochs could be enabled using new 'print_timestamps' directive from .bochsrc: print_timestamps: enable=1

- Added --enable-show-ips option to all configuration scripts used to build release binaries, so all future releases will enjoy IPS display.

- Enable alignment check in the CPU and #AC exception by default for --cpu-level >= 4 (like in real hardware)
