In the run-up to the final version of the old RealSpectrum branch (release R14), Ramsoft have put an interim version to download on their website. Build 0.97.18 of RS32, built about 10 days ago but only just put online, is more than just a bug-hunt, including with it CompactFlash emulation, MP3/OGG support (for compressed tape images), and some other goodies that I've not had a chance to look at. A similar build of the MSDOS version will be out soon too, hopefully with more release notes.
The full release of R14 should be available in the next few days, and hopefully for *nix users, a Linux build too. Following this the next main release will be the new RealX emulator - I'm drooling in anticipation.
