openMSX is the MSX emulator that aims for perfection. 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. Please read the release notes for details.
openMSX 0.7.2 is a minor bug fix release on top of openMSX 0.7.1, which had a mall bug in a Tcl script. Because of this, openMSX wasn't able to load savestates with paths that contain spaces, which is the most common case on standard Windows installations.
