The original 2D debut. Mr. Dark steals the Great Protoon and the Electoons are scattered all over the world! Now it's up to you to find every last one of the hidden cages to even be allowed into the last level to do battle with him -- don't you just love that?
Native to Win3.1/95/98. This can be incredibly irritating to get working with sound; your best bet is to install Windows 3.1 on DosBox, install Rayman under Windows 3.1, and then return to DosBox's regular DOS mode to actually play it. As of this writing, there's a handy guide to the 3.1 installation process including special drivers at http://www.sierrahelp.com/Utilities/Emulators/DOSBox/3x_install.html and I've even included the 3.1 installation files for your convenience.
If you still can't figure it out, go dig up the PlayStation port and play it instead. It's pretty much exactly the same.
