2014 May 1 openMSX 0.10.1 released

openMSX 0.10.1—StillNotOneToo—mostly fixes mostly bugs we introduced with 0.10.0 or were already present for a bit longer... sorry for those, but most should be fixed now :) There are also some small but nice additions, like much extended MIDI support on Mac (thanks Grauw!), support for harddisk images in the OSD menu and more fine grained control in which slots carts and extensions will end up. Together with openMSX an updated version of Catapult, our user-friendly GUI, was released. Again, we actually made some improvements to it this time, mostly more code cleanups to enable quite some bug fixes (mainly in the settings tab), but also some features, like ability to change cartridges at run time and support for hard disks. Please read the release notes for details of the openMSX changes.

2014 January 5 openMSX 0.10.0 released

openMSX 0.10.0—StillNotOne—adds many larger and smaller features, but most outstanding are: cycle accurate VDP command engine timing, an Android port, subdirectory support for dir-as-disk and Neos MA-20 support. These features meant a lot of work was done in practically all parts of the code, but at the same time we also freshened up much of the code using many of the new C++11 language features. All in all, it was time to release this stuff officially... Together with openMSX an updated version of Catapult, our user-friendly GUI, was released. We actually made some improvements to it this time, mostly code cleanups to make it easier to help us with this subproject, but also some small features, like ability to set up multiple IPS files, control video source and disable sprite settings and DMK support in the file filters, next to some smaller bug fixes. Please read the release notes for details of the openMSX changes.

2013 April 23 openMSX moves to Git

Today we moved all openMSX projects to Git (still on SourceForge.net), after having used Subversion for about 6 and a half years. Git is now the state of the art on source code management and rapidly getting more popular. Anyway, this means that you have to use a different way to get the latest openMSX sources now: click on one of the repos to see the instructions at the top. The Subversion repository will be deleted soon. Also, we've converted the project on SF.net from classic to Allura. You'll notice that when visiting the project page, especially when you check the new Tickets system, e.g. the bug tracker.

2012 September 30 openMSX 0.9.1 released

openMSX 0.9.1—Enigma Take Two—mostly fixes a bug in dir-as-disk that was introduced in openMSX 0.9.0, when adding support for the DMK format and low level disk emulation. We not only fixed that bug, we rewrote dir-as-disk almost completely, making it a lot more robust. Together with openMSX an updated version of Catapult, our user-friendly GUI, was released. Please read the release notes for details.

2012 August 12 openMSX 0.9.0 released

openMSX 0.9.0—Enigma—improves a lot on accuracy of floppy support, especially by the introduction of support for the DMK format. This means it should be possible to run all MSX disk software without patching it. Furthermore, our efforts to improve performance has some results: start up time has almost halved on a Dingoo A320! Together with openMSX an updated version of Catapult, our user-friendly GUI, was released. Please read the release notes for details.

2012 January 25 openMSX 0.8.2 released

openMSX 0.8.2—Small Guy—mostly fixes loads of bugs and adds many smaller features and improvements. Together with openMSX an updated version of Catapult, our user-friendly GUI, was released. Please read the release notes for details.

2011 March 12 openMSX 0.8.1 released

openMSX 0.8.1—Tasmania—builds on the previous release, in the sense that we worked out the features a little more. We added a lot of scripts to help you with Tool Assisted Speedruns (TAS), one of the reasons openMSX got officially approved as a TAS capable emulator on tasvideos.org. The reverse feature also got some updates while doing this. For the rest we have again mostly fixed smaller issues and added smaller features. Together with openMSX an updated version of Catapult, our user-friendly GUI, was released. Please read the release notes for details.

2010 October 17 openMSX approved for TAS

TASing—Tool-Assisted-Speedrun—is the hobby of creating run-throughs of video games that resemble superhuman-like playing sessions. Its main community web site is tasvideos.org and it has a limited list of approved emulators which can be used to create a new TAS and is accepted for submission. Today, the site announced that openMSX is now officially approved to submit TASes! The first MSX TAS has already been submitted by our team member Vampier, which is of course no surprise. Neither is the game: Metal Gear. Who will improve his speedrun and submit a better TAS? The game is on!

2010 June 6 openMSX 0.8.0 released

openMSX 0.8.0—CSI Dresal—includes two major new features: reverse and Laserdisc. Reverse is similar to what you can do in meisei: you can 'rewind' time with your finger tip, to correct game playing mistakes or inspect what caused a crash. Laserdisc is the Palcom system introduced by Pioneer in 1984: now you can play all the Palcom MSX Laserdisc games in openMSX! With this release we also provide a first official binary package for Dingux on your Dingoo hand held. For the rest we have mostly fixed smaller issues and added smaller features. Together with openMSX an updated version of Catapult, our user-friendly GUI, was released. Please read the release notes for details.

2009 June 30 openMSX 0.7.2 released

As promised, openMSX 0.7.2 is now available, identical to 0.7.1, except for the already mentioned bug fix. Enjoy!

2009 June 29 openMSX 0.7.2 will be here soon...

Oops, we found a problem in openMSX 0.7.1, just after we had released it... Due to a small bug in a Tcl script, openMSX wasn't able to load savestates with paths that contain spaces, which is the most common case on standard Windows installations. 0.7.2 will be available very soon to fix that.

2009 June 28 openMSX 0.7.1 released

openMSX 0.7.1—IWCA approved—includes a brand new installer with binaries which have been created in a brand new way, using Microsoft Visual C++ 2008. This means smaller binaries and also support for 64-bit Windows operating systems. Also, several long standing problems have been fixed in the Windows release of openMSX. E.g., it now includes full support for unicode! For the rest we have mostly fixed smaller issues and added some cool demonstrations of what one can do with the combination of (Tcl) scripting, the debug command and the OSD. Together with openMSX an updated version of Catapult, our user-friendly GUI, was released. Please read the release notes for details.

2009 January 7 openMSX 0.7.0 released

openMSX 0.7.0—Lazarus—includes the long awaited save states feature, fully automatic host to MSX keyboard mapping and an improved dir-as-disk feature with full transparency. Furthermore, we have added a technology preview of our new On-Screen-Display. Also we have an even better performance and several other enhancements and bug fixes on many places. Together with openMSX an updated version of Catapult, our user-friendly GUI, was released. Please read the release notes for details.

2007 December 11 openMSX 0.6.3 released

openMSX 0.6.3—Crystal Clear—includes advanced resampling for aliasing-free sound, a stereo balance setting for each sound chip, recording of separate channels, PSG detune and vibrato and some non-sound-related improvements as well. Also, a hang on Windows PCs with multi-core/HT CPUs is fixed. Together with openMSX an updated version of Catapult, our user-friendly GUI, was released. Please read the release notes for details.

2007 August 27 No Windows support anymore??

We've said it before: we need someone in our team to help us maintain the Windows port of openMSX. At the moment there is no one who provides us structural support for the Windows port. Without a person who can very regularly build and test openMSX and help in case of (rare) Windows specific issues, we cannot maintain the Windows port any longer. We may find a way to build the next release, but even that is uncertain; if we can manage, it will most likely be released (much) later than the Source and Mac versions. If you care and you want to help: please contact us as soon as possible!

2007 April 15 openMSX 0.6.2 released

openMSX 0.6.2—Oscar—includes video recording, more realistic PSG and SCC sound, significant optimizations, easier to use game trainers, as well as a lot of other improvements and bugfixes. Together with openMSX a new version of Catapult, our user-friendly GUI, was released. Please read the release notes for details.

2006 September 17 openMSX moves to Subversion

Today we moved the main openMSX project to Subversion (SVN). This means that you have to use a different way to get the latest openMSX sources now. It is explained in the updated online manual, in the Compilation Guide. Snapshots are now also taken from SVN. We removed the snapshot of Catapult, because Catapult as has been released so far is pronounced dead. A rewrite using Python and Qt4 is in the works though. You can get a snapshot of that project, instead.

Other news that we forgot to post here: there is a universal binary available for Mac OS X users, see the download section.

2006 July 31 openMSX 0.6.1 released

openMSX 0.6.1—Chernoton Meltdown—includes runtime switchable machines and extensions, a lot of new video filters (some of which use pixel shaders), as well as a lot of other improvements and bugfixes. Together with openMSX a new version of Catapult, our user-friendly GUI, was released. Please read the release notes for details.

2006 July 23 Web site restyled

A redesign of the openMSX web site was long overdue. And with the restructuring of the site, we've also included 2 different layouts. Hurray for CSS :-)

2006 July 23 openMSX needs you!

That is, if you've got some spare time and want to develop fun software for Windows. The openMSX team desperately needs Windows developers, both for coding on the openMSX code itself, and also for Catapult. Don't hesitate! Fire up you IRC client and visit us at #openmsx on Freenode.net. We won't bite. Really!
