Joyce v2.2.7 is released. Joyce emulates the Amstrad PCW on Unix, Windows and Mac OS X. Since it's written using SDL, it shouldn't be too hard to port it to other platforms such as MacOS Classic or BeOS.

Joyce v2.2.7 Changelog:
This contains code to guard against the possibility of a malicious CP/M program overwriting or deleting important files on the host computer or crashing JOYCE. If you use JOYCE / ANNE to run CP/M programs downloaded from the Internet, I recommend that you upgrade to this version.
