Manic 1: BridgedirB (and maybe the talisman solution if a harder level is needed)
Since new-formats ties the talismans to the level, rather than to the pack, Lemmings Plus Compressed can easily keep the talismans from the source versions of the levels. (I didn't bother with this with the older Flashbacks packs, precisely because I'd have to manually port each talisman over one-by-one, and ensure they're kept consistent if anything changes. With new-formats, I can simply copy the level file, and the talisman comes along with it.)
Ooh, this is another collection pack?
Lemmings Plus Compressed replaced the two Lemmings Plus Flashbacks packs when I updated the packs to new-formats, rather than being a third collection pack.
Rather than release additional compilation packs as new packs come out, my intention is that as new packs come out, I'll eventually (not immediately upon release) add levels from them to LPC, perhaps removing a few of the ones from older packs to avoid LPC becoming too large. It currently stands at 80 levels, and contains levels from all Lemmings Plus packs except LPVI. The levels it has from the packs that
were covered by the Flashbacks packs, are almost exactly the same ones the Flashbacks packs themself contained, though there are a few changes - in particular, a couple of levels were added because they were new additions or significantly improved in the new-formats conversion (the first example to come to mind being that LPIII's "I'm Going To Try Science!" is now in there - it was already a pretty decent level, but due to the culling of radiation, the new-formats version has an entirely new solution which IMO is much better).
