It is a shame that Sorcerer is to busy to attend to the mod, but it is understandable.
Since he isn't around to patch problems at the moment here are instructions on how to fix some of the more pressing issues (that I encountered at least).
LEATHERFor the leather problem, open entity_pony and add [PERMITTED_JOB:BUTCHER] and [PERMITTED_JOB:TANNER] to the list of permitted jobs and [PERMITTED_REACTION:TAN_A_HIDE] to the list of permitted reactions (you could also re-add the reactions [PERMITTED_REACTION:RENDER_FAT] and [PERMITTED_REACTION:MAKE_SOAP_FROM_TALLOW] if you don't like Sunflower oil).
If you can't find the two lists (which are incredibly hard to miss) just bring up the word finder in notepad and type in whichever, the lines don't need to be in any specific order in the list.
CROSSBOWSFor crossbows add [WEAPON:ITEM_WEAPON_CROSSBOW] and [AMMO:ITEM_AMMO_BOLTS] to the list of items the Pony Civ have available, the default crossbow is technicaly multigrasp as far as I know (I have no idea how reloading works but there are mods which add ranged weapons that can be fired and reloaded with one hand so it shouldn't be too hard to reverse engineer from say the Corrosion mod).
If you for some reason want ponies to be able to grasp things with their front hooves then open body_pony and replace:
[BP:RFF:front right hoof:front right hooves][CON:RLFL][STANCE]
[LIMB][EMBEDDED][CATEGORY:HOOF_FRONT]
[DEFAULT_RELSIZE:80]
[BP:LFF:front left hoof:front right hooves][CON:LLFL][STANCE]
[LIMB][EMBEDDED][CATEGORY:HOOF_FRONT]
[DEFAULT_RELSIZE:80]
with
[BP:RFF:front right hoof:front right hooves][CON:RLFL][STANCE][GRASP]
[LIMB][EMBEDDED][CATEGORY:HOOF_FRONT]
[DEFAULT_RELSIZE:80]
[BP:LFF:front left hoof:front right hooves][CON:LLFL][STANCE]
[GRASP][LIMB][EMBEDDED][CATEGORY:HOOF_FRONT]
[DEFAULT_RELSIZE:80]
This should turn the two front hooves into grasping limbs.
Remember that Unicorns have that weird tentacle horn which counts as a grasper along with the mouth, so if anything THEY should be able to use two handed weapons and items just fine, adding shields to this list should logicaly give you shields for your unicorns to use (but I don't know what it does to Earth Pony and Pegasi NPC's which could possibly spawn with only a shield...).
P.S There is actually a "pie thrower" ranged weapon in pony_weapons which hasn't been added, but it doesn't have throwable pies yet.
Just saying, Sorceror evidentely had some plans on the ranged weapon problem.
P.S.S Testing did indeed show that Earth Ponies and Pegasi can't use ranged weapons, they will drop the carried ammo and keep the crossbow while Unicorn ponies will keep both and successfully use the crossbow.
Pegasi and Earth Ponies can still use most vanilla two handed weapons fine though, probably due to their size, so pikes and haleberds should be pretty viable if you get ahold of them.
UPDATING TO NEW VERSION OF DF(??)With my abyssmal knowledge of how the DF files interact with each other I have no idea if this is the correct way to manually update the version or not, but this is pretty much how I did it and I haven't come across any issues thus far.Drop all pony related Raw>Objects files into the new version of DF's Raw>Objects (which translates to, anything that doesn't ask for an overwrite), wether you want to keep/remove vanilla civs (dwarves, elves, humans, etc) is up to preference I guess (I assume that it should be possible to prevent them from spawning by either changing MAX_STARTING_CIV_NUMBER and MAX_POP_NUMBER to [MAX_STARTING_CIV_NUMBER:0] [MAX_POP_NUMBER:0] or perhaps even by deleting their entities and bodies altogether, if they don't exist then they can't exist, amirite?).
Don't forget to copy language_words, language_Equine and the old b_detail_plan_default files (which hold the tissue layer data for mane, tail and griffon feathers, without it weird shit starts to happen to descriptions, yes overwrite the two new files with the two old ones).
AS FOR THE WHEELBARROWS...To make the pony civ use wheelbarrows and minecarts just add [TOOL:ITEM_TOOL_MINECART] and [TOOL:ITEM_TOOL_WHEELBARROW] to the list of tools they use in the entity_pony file.
If you have trouble differentiating between ponies for caste specific roles (if you are nitpicky like me and only want Unicorns dealing with craftstuff and earth ponies working on farming, etc) then use the Mastercraft mod's version of Dwarf Therapist, it registers and displays castes which the original DT doesn't.
Another thing, there is a copy of "reaction_weather" that you should delete to make the weather workshop work properly as Sorcerer mentioned a while back.
AND there is a DUPLICATE of the "Combine 25 Research", just open the reaction_research file and remove either of the STUDY25 reactions.
And I believe that covers most of everything?
Errorlog should be 100% clean after this and game should be ver 34.11.
Here is also Darekun's post with the pony sprites he made a while back if someone missed it...
