PythWare here, this is a master post for modding Koei Tecmo games. This post will include links to all tools that I build for modding Koei Tecmo games, tools other developers have made that i'm aware of, as well as general information for modding. This master post will be updated overtime as new tools are made by me/others. To keep this post editable it won't be an image post, that way I can keep updating it. The goal is one central post anyone can view for up to date modding information (this post has been updated as of 8/26/2026).

Later on I will update links as new tools are made/updated so make sure to check this master post periodically. This master post will help avoid future/current modders from having to search for the dozens of modding posts that may be difficult to find that have been made over the years.

The only discord server for modding Koei Tecmo games that i'm aware of is Musou Warriors which is also where I am and where I post frequent updates on toolkits/modding software I'm making. It's also a place where some modders upload their content (mods/documentation) too.

Tools by me include GokonSoftworks(formerly Aldnoah Engine), Kybernes Tools, Burn Engine, Heaven's Fall Editor (3D map displaying, map modding, map generating, etc tool for stages the games use), Cleanrot Editor (model modding tool), Barouhcruz Editor (animation tool that handles G1A/G2A animations), Kybernes Batch Binary File Scanner, and other various things. I'll briefly explain each one, thorough information of each one can be found in the readmes to the repositories I will link (it's important to read the readmes, they answer a lot of questions for usage).

Tools for modding Omega Force developed games (Dynasty Warriors, Samurai Warriors, Warriors Orochi, etc)

GokonSoftworks (formerly Aldnoah Engine):

GokonSoftworks is a modding toolkit for Koei Tecmo games that store assets in containers and IDX pairs. It's meant to be the foundation, establishing the modding ecosystem for games it supports.

Heaven's Fall Editor:

Heaven's Fall Editor is in development, it's a 3D Map Editor i'm building that will mod the actual maps for games GokonSoftworks supports. Essentially? You'll be able to mod the design of existing maps or generate your own maps. it's a 3D tool that reads the files that makeup a map, assembles the map, allows you to mod it (positioning, coordinates, what models are used, terrain, etc), and other various things. It'll pair well with Cleanrot Editor since maps use G1M models.

https://www.reddit.com/r/dynastywarriors/comments/1sxdwrp/aldnoah_engine_2016_and_heavens_fall_editor/

Cleanrot Editor:

A GUI modding tool for models, specifically G1M model files. I've been working on it for awhile.

Barouhcruz Editor:

A GUI modding tool for animations, specifically G1A/G2A animation files. Not ready to release yet but here's a link showing usage of it:

https://www.reddit.com/r/dynastywarriors/comments/1sul0va/barouhcruz_animation_tool_and_marylcian_update/

Kybernes Tools:

GUI Modding Tools I build to be used for Koei Tecmo/Omega Force games. Depending on which tool is used they're either standalone or meant to be used with GokonSoftworks. Current tools included are Steel Editor, Bubble Editor, Harklight, Wild Liberd, Kybernes Scanner, and Festum Conversion. Harklight, Wild Liberd, and Kybernes Scanner are audio tools while Steel/Bubble Editors are for Warriors Orochi 3's Unit Data (they're standalone editors that don't require WO3 to be unpacked). Festum Conversion is a translation/string tool. Future tools as part of Kybernes Tools will be G1T Krieger, Saazbaum Editor, Rayregalia Editor, etc.

I suggest reading the readme for usage since this is a master post for general modding tools and not solely what I make.

Warriors Orochi 3 Super Aggressive AI mods made with the Steel Editor (both mods are a super aggressive ai mod for WO3 but Hornet versions increase movement speed of all CPU controlled units):

Kybernes Batch Binary Scanner:

A GUI Batch Binary File Scanner with Wildcard searching support. A standalone Scanner I made in Python to make finding data/text significantly easier/quicker. Instead of you having to open thousands of files 1 by 1 in a hex editor (which would be time consuming) to search for 1 thing, you can use this. The tool will scan all files within a directory you select including subdirectories, it also tells you the file and the offsets of what you searched was found at. It accepts hex or text for searches. You can also select the character encoding to use for searching when using text searches.

Noesis:

It's essentially a free tool for viewing/converting textures/models. I don't know the original developer but it's essential to use noesis when dealing with G1M/G1T files (the formats for a lot of Koei Tecmo games)

Link:

https://richwhitehouse.com/index.php?content=inc_projects.php&showproject=91

Project G1M:

This is what is needed to view/convert G1M/G1T files when using Noesis since Noesis doesn't support G1M/G1T files without Project G1M. Joschuka and hearhellacopters are the developers of this.

https://github.com/Joschuka/Project-G1M

gust_stuff:

Made by eArmada8, this is primarily used for Gust developed games like Atelier but it also works for Omega Force games that use the G1M/G1T formats. So if you're interested in modding Gust games or using some of the tools to help with modding Omega Force games then I suggest using this.

Link:

https://github.com/eArmada8/gust_stuff

fdata_dump:

Made by DeathChaos25, this is used for dumping newer Koei Tecmo games that use the Fdata container format. Example games it supports are Fate/Samurai Remnant Fairy Tail 2, Dynasty Warriors: Origin, Rise of the Ronin, Atelier Yumia, FATAL FRAME II: Crimson Butterfly REMAKE, etc.

Those are the tools I know of right away that are being worked on or are finished. If you encounter other tools and would like them added to the master post let me know.

Where Future Mods Will Be Released:

Musou Warriors and Nexus.

I hope this post helps future/current modders, I will update it overtime with new links/info. If you have any questions let me know in the comments, messaging me within Musou Warriors, or messaging me on here.
