"I was playing this game well before I became a fan of Friendship is Magic," RelicShadow explained. "My newfound interest lead me in search of potential mods for it. After all was said and done and I had my big pile of mods, I decided I might as well be the one to make [the megamod] happen."
The conversion package includes 90 audio tracks, renamed nations, new achievements, pony tank skins, and rainbows out the wazoo. Reportedly, it is a somewhat tricky to get the mod to work correctly, and RelicShadow recommends that no other mods are installed in addition to this one.
