Raymanimator is an open source community project created by Rorias. The purpose of this program is to allow creating and editing rayman animations for Rayman 1, Rayman 3 GBA and more. This program comes with the spritesets for multiple games and a few example animations.
To install a version, simply select "Releases" on the right-hand side of the repository and download the appropriate zip file. Unzip and run the .exe to start animating :)
