Want to get into Heroes of Might and Magic 3? Avoid the Ubisoft HD version at all costs. They do not come with the expansions and look worse in some places than the originals. Instead, get the HoMM3 complete pack on GOG or in the Mega link listed at the top and download the HD mod at (https://sites.google.com/site/heroes3hd/)
If you're looking for HoMM3 mods, check out Horn of the Abyss (http://www.hota.acidcave.net/download.html) for a new faction based off the Regnan Empire and rebalancing or Wake of Gods (http://www.maps4heroes.com/heroes3/in_the_wake_of_gods.php)

Want to get into the main Might and Magic series? It's never too late to try them, here's MM1-6.

Just get Grayface patch for MM6 at (https://sites.google.com/site/sergroj/mm#TOC-GrayFace-MM6-Patch-v2.0), check out the optional files like the mouselook mod or tool to rebind controls, and copy all .mp3 files from your "Sounds" folder into a new "Music" folder. Also here's MM7 which also has a Grayface patch you can download.

If you want to start from the very beginning, you can play the mac versions of MM1 and MM2 which have better graphics and interface.

MM1 has to be played through vMac while the rest can be played on BasiliskII. Just remember to go to the control panel and turn off outSPOKEN8 if you get bombarded with text-to-speech when you open up BasiliskII. More info can be found in this post: (http://www.rpgcodex.net/forums/index.php?threads/marathoning-might-and-magic-games.109852/page-2#post-4639284)

If you want to play Might and Magic 3-5 with higher quality audio, download MUNT (https://sourceforge.net/projects/munt/) and these roms (https://mega.nz/#!pA5HzDyJ!THTL9MSIs_WN5XBEexIkMNBo7nfNWAMT6QmRDHvbhtk)

To get mt-32 sound working you have to open up dosbox and type in "mixer /listmidi", find out which number correlates with the mt-32 sound emulator, and then you have to go to "dosboxMM4-5.conf", find the midi section, then set midiconfig = whatever number your sound emulator is set as. Note that MM4-5 is prone to crashing with music enabled when using MT-32 sound but you still get higher quality effects.
