FSModTool is a datamining and modding tool for From Software's PlayStation-era titles, previously known as KFModTool as part of the KingsFieldRE project. It was built with focus on King's Field II, but has some preliminary support for other games as well.
This is the fruit of the community's efforts in understanding how these games work and is here in the hopes that it might provide help to those who are interested in helping reverse engineer From Software's early games.
If you intend to use FSModTool for modding purposes, please keep regular and plentiful backups of your mod files. It is very experimental software with emphasis on being used for datamining and reverse engineering efforts.
If you need help or would like to discuss early FS game internals and reverse engineering, join The FromSoft Modding Committee Discord Server!

As of writing, King's Field III maps will load but will have incorrect entity/sound/weapon names and missing objects since we haven't documented KF3 yet and the KF2 names are loaded instead. Support for all games except KF2 is only for loading model and texture files.
This project could not have been written without TheStolenBattenberg's Psycpros project.
Monster Mesh IDs were mostly found in Shrine Maiden's King's Field II code page.
A lot of the work discovering fields of the map file structures was done by Mendzen.
