I just released v0.2 of the **XXL Editor** : https://github.com/AdrienTD/XXL-Editor
AdrienTD
It has improvements and new features, but not only that!
There is support for other games than just XXL1: XXL2, Olympic Games, on PC as well as console versions!

For example, it is now possible to fully mod XXL1 on GameCube, including textures, models and sounds! (despite model import still being buggy atm)

There's also that brand new menu at the screen where you can create projects and keep in a list, so you can easily work on multiple mods without the need of changing the ini file every time!
