Makaqu (engine of Quake for Windows and Dreamcast) has launched a new version!

It should warn that this version is alpha and has not been tested on the Dreamcast. Furthermore, are aware of some bugs, such as transparencies BSP rendering, and some clipping. As expected for an alpha release, some of the new features are still incomplete and possible bugs.

This release does not include the file PAK10.PAK, but there are binaries for Windows and Dreamcast (not tested), along with a map of evidence.
