openMSX is confirmed to run on the following operating systems: Linux, Win32, Mac OS X, FreeBSD, OpenBSD and NetBSD on x86, x86-64, PPC, ARM and Sparc CPU’s.

Keep in mind that openMSX is still evolving at a considerable speed. We do try to be backwards compatible for at least one release, though. Keep this in mind if you create machine descriptions, ROM database entries etc. This happened between 0.4.0 and 0.5.0, for example.

Until we reach version 1.0.0, file formats can change in an incompatible way without backwards compatibility.

Make sure you read this if you haven’t used openMSX before, but also to learn more about the new and changed features. In “doc/manual/index.html” you can find a set of HTML manuals for openMSX.And of course the usual various bug fixes.For Laserdisc support (which is optional), added dependency on libogg, libvorbis and libtheora.Added platform/CPU support for: PA-RISC, Dingoo, SuperH, Nokia N900/Maemo, MacOSX 10.6 / 64-bit, GNU/kFreeBSD, Atmel AVR32.Added emulation of the trackball (thanks n_n).– minor fixes in V99×8, V9990, YM2413 and YMF278 emulation.Added support for balance per channel, including support for the “stereo” effect of the FM Stereo PAK and the stereo PSG of the Pioneer PX-7.Added emulation of Palcom Laserdisc games on the Pioneer PX-7/PX-V60 (note: not visible in screenshots and video recording yet).

Added reverse: go back in time to correct mistakes or replay your actions (use PgUp and PgDn to control, enable visualization of this feature with this console command: set auto_enable_reverse gui).I haven’t used this emulator before so let’s head straight to the changes.
