There are plenty of new features and bugfixes in this release (far too many to list in a reasonably-sized news post), so here's the highlights of what has been improved:
- Added support for emulating the ColecoVision and the NES (mappers 0 and 1 only)
- Fixed various bugs in the Z80 core
- Fixed priority on sprites in TMS9918 video modes
- Added support for PAR cheats for SMS games
- Added support for roms in zip files, as well as gzip and bzip2 compressed roms
- Added support for a few odd mappers in SMS games released in Taiwan and Korea
- Added support for browsing directories in the Dreamcast GUI
- Added support for libkosext2fs (so you can put roms and such on an ext2 formatted SD card)
