Es ist eine neue Version von openMSX erschienen.
A new version of openMSX has been released.
Release Name: 0.6.1
Notes:
Release Notes for openMSX 0.6.1 (2006-07-30)
============================================
This release includes major internal changes, although many are not visible
from the outside.
It is now possible to switch from one MSX machine to another while openMSX is
running. This will reset the MSX of course.
Also, it is possible to insert or remove cartridges (extensions or game ROMs)
while openMSX is running. This does not reset the MSX, but the MSX system was
not designed to support insertion or removal of cartridges while the machine is
on. Although doing so will not damage openMSX (unlike a real MSX), it is
possible the MSX will hang if hardware is removed that was being used, or that
newly inserted hardware will not function properly until you reset the MSX.
A new advanced video renderer was added: SDLGL-PP. This renderer requires
OpenGL 2.0 and uses pixel shaders to postprocess the image. For new video cards,
this is a very efficient way of scaling the image. For old video cards, please
stick to the SDL or SDLGL renderer. Not all scalers are implemented yet:
"simple" and "ScaleNx" work, as well as the new "TV" scaler, which is exclusive
to SDLGL-PP.
New or improved emulator features:
- Run-time switching of machines:
change: set machine
query: set machine
- Run-time switching of extensions:
insert: ext
remove: remove_extension
query: list_extensions
- Run-time switching of ROMs:
insert/change: carta
remove: carta -eject
query: carta
- New command "hda" to change the IDE harddisk ("hdb" for second drive etc).
This is allowed only when the power is off, for the safety of your data.
- SDLGL-PP renderer (OpenGL-2.0), with the following exclusive features:
* scale factor 4
* TV scaler: brighter pixels are drawn bigger
* 3D monitor effect: (arcade look)
set display_deform 3D
* horizontal stretch: (MSX aspect ratio)
set display_deform horizontal_stretch
- Monochrome monitor effect:
monitor_type
- Video noise effect:
set noise
Low amounts of noise (for example 2.5) can make the video look better, high
amounts are just a gimmick.
- Brightness and contrast control: "set brightness " and "set contrast
", where 0 is neutral.
A small decrease in contrast will make the noise look better.
- Preload disk image: avoids repeated spin-ups when loading from PC CD-ROM.
- TCL procedures can now have a help text and TAB completion.
We also added help and completion to the TCL scripts that ship with openMSX.
- New console command "about" which searches for commands (built-in or TCL
scripts) that seem to be about the given keyword. Useful if you forgot the
exact name of a command.
- Watchpoints for I/O port and memory access:
debug set_watchpoint [] []
debug remove_watchpoint
debug list_watchpoints
Where type is one of "read_io", "write_io", "read_mem" or "write_mem".
Address is in range 0..255 for I/O ports and 0..65535 for memory.
Condition and command are the similar to the "set_bp" command.
- Detection of DI/HALT (hanging MSX).
- Detection of Undefined Memory Reads (UMRs).
When memory is read that was never written to, a TCL procedure is called.
You can make your own, or use the included procedure named "umrcallback":
set umr_callback umrcallback
This is "valgrind" for MSX 
MSX device support:
- IDE CD-ROM support: the "ide" extension now contains a CD-ROM drive in
addition to a harddisk. You can insert ISO images with the "cda" command,
or "cdb" for the second CD-ROM etc. There is no support yet for audio tracks.
Note that you have to run IDECDEX in the emulated MSX before you can use
CD-ROMs; you can download it from Sunrise (http://www.msx.ch/sunformsx/).
- Support for V9938 with only 16kB VRAM, as used in the SVI-738.
- Major V9990 improvements.
- Minor sound differences between two different PSG types (AY8910 and YM2149).
- Added Ninja-tap, a joystick port expander.
- Added DDX-3.0, a port-based external floppy interface.
- Small bugfixes in various devices: VDP, RTC, FMPAC, MegaRAM, IDE.
Build system, packaging, documentation:
- OpenGL support now depends on GLEW (http://glew.sourceforge.net/).
GLEW is a library which allows us to conveniently use of GL extensions.
- Build fixes for Intel Macs.
And of course the usual various bug fixes.
In "doc/manual/index.html" you can find a set of HTML manuals for openMSX.
Make sure you read this if you haven´t used openMSX before, but also to learn
more about the new and changed features.
Known issues / caveats:
- Emulation is not perfect yet.
See the bug tracker on sourceforge.net for known bugs.
- Until we reach version 1.0.0, file formats can change in an incompatible way
without backwards compatibility. This happened between 0.4.0 and 0.5.0, for
example. Keep this in mind if you create machine descriptions, ROM database
entries etc.
- openMSX is confirmed to run on the following operating systems: Linux, Win32,
Mac OS X, FreeBSD, OpenBSD and NetBSD; on x86, x86-64, Sparc and PPC CPU´s.
Running on other operating systems (wherever SDL runs) or CPU´s should be
possible, but may require some modifications to the build system. If you are
compiling on a new platform, please share your experiences (see below for
contact info), so we can make openMSX more portable.
- CPU and graphics performance varies a lot, depending on the openMSX settings
and the MSX hardware and software you´re emulating. Some things run fine on a
200MHz machine, others are slow on a 2GHz machine. For performance tuning
tips, see the Setup Guide.
