rlvm provides a replacement for the RealLive.exe used on several popular visual novel type games, allowing you to play them under other operating systems.
rlvm currently plays Kanon, AIR, CLANNAD and Planetarian (along with some non-KEY games). rlvm implements the rlBabel extensions, so it can play NDT's Kanon translation and Baka-Tsuki's CLANNAD translation patch.
Support for AIR (and some non-KEY games).
Support for loose Ogg Vorbis file voice patches and the KOE archive format.
Large number of small graphical fixes.
Universal Binary (PPC/Intel)
Mac OS X 10.4 or higher
