Hi Svaan,

Welcome to the Forums! Yes, it's very possible, and this is great timing, as I recently helped two Forum members get their really old levels from CustLemm/Lemmix converted to New Formats NL. For this, you can either attach your level files here, or if you don't want to do that, just PM them to me and I'll be more than happy to do the conversion for you.

Enjoy your stay here and looking forward to seeing you more around the place
