Hello, everyone!
I've posted today the first public alpha of MissionComputer 4.0 'Crusoe' for your examination and testing. This is the first version of MissionComputer to be a universal binary for Intel- and PowerPC-based Macintoshes; it's also significantly more stable in handling files and various other operations, and adds a shďp editor and numerous smaller features.
This is still a pre-release version of MissionComputer, so it is incomplete, and you should be sure to keep backups when using it. In particular, when editing a system, you should be careful not to separately edit any of the spöbs included in it, or your changes may be overwritten; the help content is also largely incomplete.
Please report any bugs or usability issues you find so that I can fix them for the release version. I haven't been able to test this extensively on Intel-based computers, so though I believe I've dealt with all the potential problems that could occur because of their little-endian number system, I'd appreciate hearing from anyone who meets with trouble (or success) running it on current Macintoshes.
MissionComputer 4.0.0a1 is an 11.4 MB (universal binaries are large) disk image available from <davidarthur.evula.net/beta/crusoe/MissionComputer400a1.dmg>. It requires Mac OS X 10.3 or greater.
