Amicitia Wiki:About

Amicitia refers to both a Windows application developed by TGEnigma, and a network of websites and documentation maintained by both him and ShrineFox. The name is derived from the latin word for friendship, a common theme throughout the Persona series.

Application
Development for Amicitia began in January 2016 |according to the Github page. It was written in C# and originally began as a replacement for RMDEditor, which was considered difficult to add new features to. The first few builds of Amicitia allowed users to open PAC (BIN) archives from Persona 3 and Persona 4 and extract, modify, or replace the files inside. Later updates allowed you to preview TMX files in the program and export them to PNG format (you can also use it to convert a PNG back to TMX). This was especially handy as the TMX editor left in SMT: Nocturne was prone to errors and we had to rely on python scripts to extract and replace TMX files in SPR or PAC containers, which Amicitia could handle using a treeview. From the beginning, Amicitia was planned to support RMD editing as well. Although RMD's TXD texture format (as well as the editing of animations) was supported early on, it wasn't until July 2017 that you could import and export fully rigged 3d models with Amicitia. This long-awaited functionality earned the unofficial moniker "the rigger" as it underwent on-and-off development. Currently, Amicitia is still the most used all-in-one Persona editing suite, boasting the following features:
 * Import and export TMX image data as PNG
 * Import and export TXD image data as PNG
 * Add and remove textures from SPR, BIN and TMX files
 * Export RMD model data as dae, import as FBX
 * Re-order, import, and export animations in RMD files
 * Re-order, import and export ADX sound data in ACX files

Network
The name Amicitia is also used on several different platforms for the Persona modding community. Although it is a direct reference to the name of TGEnigma's program, the naming convention is also inspired by the bond shared by the community in their interest to research the games.
