Master of Magic is a well-loved game that had issues.  Kyrub attempted to fix the problems of the final v1.31 patch in his v1.4 fan-made bugfix "Insecticide" patch.  Now, another user Seravy has stepped up to edit the machine code of the .EXE files by hand and is producing a v1.5 patch to fix everything that kyrub couldn't get to.  The diplomacy system works, for the first time ever.  The computer players will actively participate in diplomacy, asking you for treaties, warning you if you get too powerful, and rewarding you for attacking their enemies.  316 separate issues have been identified and fixed in this new release.  Game crash bugs, display bugs, spells not working correctly, computer players using spells nonsensically or ineffectively, CP-to-CP relations, so many of MoM's problems are history.  Now, the release candidate is up and needs testers.  This is the official forum thread for reporting experiences.  

To install: first, install the latest version of Master of Magic v1.31.  Then, download the highest-numbered RC file from this link.  Unzip the file into the Master of Magic directory and overwrite all.  Run under DOSbox.  (set cycles=max under DOSbox or just press CTRL-F12 a bunch of times to speed things up)  If you need any help installing or getting the game running, just send me a message.
