I think if he owns a legal s2 he can ask about the crack for the old version of lfs
I dont remember clearly but there was some kind of topic about the same matter and the user who asked for the crack for unlock old version of lfs ( The one with the lx8) didnt have any problem in the forum nor with the dev or mods.
It really is a shame you can't watch .spr files from other versions.
I sometimes browse this forum, coming across old .spr files which I can't look at.
Maybe there should be a .spr player out side of LFS which could play all the .spr or .mpr.
