how do i get this to work >.> never tried using a mod...other then the ironhande graphics pack
First, you'll need 7Zip to extract the files. You'll find thirteen text documents in extracted folder, put these in the objects folder inside the raw folder inside the folder you have Dwarf Fortress installed in. You'll know you have the right one because you'll be asked if you want to replace item_food.txt. Click yes if you want to replace biscuits, stews and roasts made in kitchens with cupcakes, muffins and baked bads, or click no if you don't. Now that that's done, all you need to do is generate a new world.
Be sure to check the civilisations in the legends mode, so you can make sure you pick a pony civilisation, which you do by tabbing through the menus on the site locator until you see a list of playable ones, so you can pick whichever dwarven or pony civilisation takes your fancy. I'd advise you to set the number of civilisations fairly high, because I'm pretty sure worldgen only checks to see if at least one playable civ survives world gen, and the ponies seem to hate the goblins more than anyone else judging by the frequency of wars between the two in legends mode, so dorfs might outlast them.
I'm currently playing this mod a bit to give it a chance to show me any bugs so I can fix them before it becomes too ungainly. Some changes I'm already going to include in the next version so far include:
Reducing pony size from 450 kilos to just 300, unless there are violent disagreements*
Giving ponies more suitable gloves, as they'll currently wear mittens, gloves and gauntlets in their grasping mouths and on their horns. I'm a bit stuck for what to call these. I suppose a handkerchief or bandana could be used to cover a mouth or horn, and making sure they have appropriate helms that cover the head and all it's dependants should be enough for defensive purposes.
Add parasprites. I'm currently imagining them as food thieves, guzzlers and grazers with prolific cluster sizes, and either slightly sentient like gremlins or vermin hunters like cats to make slaughter difficult if anypony is foolish enough to tame them. Maybe add musical instruments as weapons?
Evil pony civ, including dark and evil-looking hair stripe patterns. Perhaps also a more dorfy, "cave pony" civ, too, and split the animal and plant use permissions up a bit(they're far too generous as is, unicorns as embark supply options?).
*Actual pony sizes vary quite a bit, from 150 kilos to 500 kilos, but zebras, which we can use for comparison because of Zecora, range from 225 to 430.
