Thanks to namida, the SuperLemmini tileset was converted easily and now the conversion is well underway! I have Hellish, Retro, and the second half on Insane left to convert. Thus far, only one level has had to bite the dust, and I have three new levels already planned for the inevitable time when more will have to be removed. Hopefully, SubLems will be released for NeoLemmix fairly soon!
Also, I'm already starting work on a new NeoLemmix pack. Not saying anymore, just putting it out there.
