In the raw/objects folder you have to manually edit all the creature, tool, inorganic and plant objects. They have a this tag (TILE:xxx), that has to be fitted to the tileset.
It is a lot of work
EDIT: Wrote a little summary to replace the first forum post for the next version, you think it is ok ? Or too much text ? I cant really just list all the features one by one anymore, there are too many.
What is Masterwork Dwarf Fortress ? Formerly I listed most of the features in this post for people who never heard about the mod and want to get a little overview. I now changed this, since it makes no sense. This Mod is not just a mod anymore. Every single part of DF that can be toyed with has been altered and hopefully made better by this compendium. Included mouse macros, additional hotkeys, mouse support, a selection of ingame tips, uniform templates, pre-set worlds with specific topics, embark profiles, a custom font, about 400 custom creature sprites, a program that allows to alter 90% of the mod yourself, several balancing features that allow to make the game harder or easier, a custom arena, background sound... a giant manual, building guides with details about every single reaction, tables about new materials and values, wallpapers, a total of 8 different tilesets and more. My Point ? All the features I just noted are not even the ingame stuff added by Masterwork DF. So far this were only extras, little things by the side.
The main part of the mod are new fortress mode additions. A total of 850+ creatures, 800+ new reactions, 60 new building, over 1000+ plants, trees, weapons, ammo, armor, food, toys, engraving and instruments, up to 25 invading races, cavern sieges and slaves, golems and landmines. Caste System, Farming trees, Throwing weapons, weapon and armor upgrades, armoring pets, alternate industries to replace metal, alternate food and booze sources, hidden fossils and spies that infiltrate your fortress. Pray to armok for aid, defend yourself with turrets and mines, research firearms or magic, hunt kobolds for loot, while a disease ravages your fortress, or lock away your magic experiments gone wrong. A smelter catches fire, or a miner catches the black lung... goblins and FBs are not the only things you have to look out for.
One feature that is most dear to me is the change in tactics. You can not play by bunkering yourself in. Some features require you to kill megabeasts, other need trading, blueprints and research, hunting in the caverns, defeating the HFS, exploratory mining, avoiding dangerous warpstone. You can find hidden fossils bearing special items, or gemstone that produce water. You can fell crystal trees and fashion pikes out of them, or hunt gem scarabs for diamonds. Trading is very, very important in this mod, I cannot stress this fact enough. You get unique items from other civs, you can order from all of them, buy slaves or dragons, constructs and special materials, foreign weapons and armor.
This mod adds more flavor and atmosphere to the game by giving races specific items, changing the looks of the caverns, which are now polar opposite to each other and adding custom profession names and castes.
You might say: "But this mod is too big, I only like half of the features"..and I say: No Problem. With the included MasterworkDF Settings.exe you can enable and disable parts of the mod, just by pressing a button. No modding experience needed. With over 5000 possible combinations you will find one that suits you.
I did save the best part for the end. Standardized materials and reduced item count. You will notice that many rocks leave only dust, invaders leave less items, some redundant clothing is not there... this will lead to higher FPS. You will also notice that leather is only called leather. Not "creature-name" leather, but only leather. The same goes for silk. And hair, milk, meat and blood, bones and wood. You wont have to scroll through 50 building materials in your list, but only 10. This is the very core of the mod. This will make playing DF a lot easier on the user, and... increase your FPS by about 25%. No joking here. This mod is about 3 times as big as normal DF and still manages to run faster.
For a full list of features please refer to the included manual and guides. It should cover 95% of the questions. There is also a fan-based Wiki and of course this thread for your convenience. If you experience any problems with this mod, please sent me a PM with more info. I added several known Adventure Mode Mods as well, but I do not actively work with adv-mode. I cannot help you with any issues there, but am still grateful for feedback about it.
PS: I would add a little table with a list for the tl;dr people as well.
