You need to have parties and they have to post looking for requests on the agency board; it's just so you can find open parties for dungeons and stuff

Sadly not, You could simply use the shadow equipment headgear slots for this though.

This is probably due to the client features you're looking for being in a later client date. Some features are hard coded into the clients themselves.

These are from job level bonuses. The file you want is Job_db2.txt

You would do something like
mes "What's up "+strcharinfo(0)+", all good?";  

You would either need heavy client edits or just simply upgrade to a 2018 client

yes this is possible; It requires a source edit though; Give me a few moments to find something for it .   https://github.com/rathena/rathena/pull/2849

With 2018 Clients you can do one of two things to support langtype 1;
1. In your `luafiles514/lua files/` folder there is a folder called "Service_Korea" and within it a file called "ExternalSettings_KR"; Rename the folder to "service_usa" and the file to "externalsettings_usa"
2. With NEMO diff your client to use the "Always read Korean External Settings"
 
This is not true so please do not spread false information

Its not located in System folder. Thats to remove the icons from the minimaps. Use this link/file to remove them all if thats what you want. https://github.com/TheDerpySupport/Untold-RO/blob/master/data/luafiles514/lua files/signboardlist.lub

You do not need to create a script for this; GM Level 99 can already do this by using #job <player> <job>; It will run as the player using the command

You'll need at least a 2018-05-30 client to view Star Emperor and Soul Reaper; There may be an option in the script to save costume because Secrets has explained to me how it saves the costume

Well this is my script you're using so It's relatively easy to understand;
if (rand(0,9) == 2){ getitem 26080,1; //Credit specialeffect2 EF_TEMP_OK; mapannounce strcharinfo(3),strcharinfo(0)+" has caught a ATM Credit Card x1!",bc_map,"0xff77ff"; } This would be 10%
rand(0,19) would be 5% and 1% would be rand(0,99)

For Langtype 1 you need to change the service_korea folder to service_usa and externalsettings_kr.lub to externalsettings_usa.lub

Yes it's called Signboard.lub located in luafiles514/lua files/;
If you'd like you can use my Signboard file to overwrite the default one.

The complete pack has to be manually updated and is not ideal for trying to run a server from;
As for the costumes, yes, you need to add them to your GRFs.;
We recently just added support for Star Emperor and Soul Reaper within this week and you will have to download rAthena from our git(link in my signature) and you can follow the wiki(also in my signature) for installation help.

In Renewal all weapons and shields have ASPD penalties, You can either disable renewal(requires recompile) or change the penalties at db\re\job_db1.txt

You can do this using an itemshop type NPC.
 
-%TAB%itemshop%TAB%<NPC Name>%TAB%<sprite id>,<costitemid>{:<discount>},<itemid>:<price>{,<itemid>:<price>...} <map name>,<x>,<y>,<facing>%TAB%itemshop%TAB%<NPC Name>%TAB%<sprite id>,<costitemid>{:<discount>},<itemid>:<price>{,<itemid>:<price>...}

This is due to you trying to use transparent pixels/anti-aliasing on the image instead of solid pixels; You will need to completely redo the outer edge of the image in a solid pixel and then when you fill the transparency with pink it will be fixed.

i = getlook(LOOK_CLOTHES_COLOR); setlook LOOK_CLOTHES_COLOR,1;
setlook LOOK_CLOTHES_COLOR, i;
The top part you put in your OnEquip and the 2nd part is OnUnequip;

It means it generates a number at random 1~50 and if it lands on 1, 2, or 3 you win; You can either lower the rand(50) or increase the number less than to look for.

You need to edit the signboard lub file.
https://github.com/TheDerpySupport/Untold-RO/blob/master/data/luafiles514/lua files/signboardlist.lub
You can download this file and place it in the appropriate location to remove them all

Check out my files on it.

For the last part you have to set your packetversion in source and recompile your server;
Àΰ£Á·(Job/Hair)/¸öÅë (Job)/
So it's a female act file you're missing. As far as the costume_11 folder I have no clue but you probably need to upgrade your kRO files.
