Skops in Rayman Designer
Work-in-progress hack, using my local working copy of https://github.com/Adsolution/Ray1Map
Basically, I transferred all the missing sprites (ETA/DES files) from Rayman 1 to Designer, using a function which is already available in upstream Ray1Map, then messed around to place Skops himself in the first Cave level.
Firstly, the palette is messed up, but that's to be expected, since Designer can't use as many palettes as Rayman 1. Secondly, he clearly doesn't work properly. Not sure if that's because there's code checking for the right level, or just because his code was completely removed from Designer (the latter is possible).
