A long long time ago, I was a DAT modder for FFXI. At one point I was actually spending more time making DAT mods than playing the game. And I know there was a brief time where I had unsubscribed from the game but kept making mods. It was a lot of fun and quite rewarding, is what I’m saying.
If you don’t know, all the resources for FFXI were stored in .dat files. Someone had created a program that let you take those files and extract the textures, alpha maps, and meshes from them, edit those files, and put everything back together. Replacing one DAT file with another allowed you to change what that model looked like in-game. Being a huge fan of playing dress-up in games, I was totally charmed by being able to make armor sets that looked cool to me without having a level restriction. These mods were technically against the TOS, but since they were just armor swaps they didn’t actually let you cheat or anything.
I originally uploaded my DATs to some kind of file sharing site, from which they have since been removed, and submitted them to FFXIDATs.com, a site that sadly no longer exists. But I had such a great time and I loved the community there. I learned a lot about 3D modeling and game assets. I recently found an old USB stick on which I had backed up all my DAT mods, so I thought it would be fun to share them with the world.
