Achievements are now fully functional.
Or, "Talismans", as I actually called them (I think I mentioned earlier that I was considering this name), to keep a Lemmings theme to it.
The only thing currently missing is I haven't added any way in-game to distinguish between Bronze, Silver and Gold. That will come later; but for now, you can see the list of them, and which ones you have / haven't received. That probably will not be implemented in the first version to have these, as it'll require a MAIN.DAT modification to store the graphics of the various types.
Just for reference, the way they're saved in the save file
does allow changes to be made to the talismans without players losing them, including reordering them or changing their ranking (bronze/silver/gold).
Anyway, let's get some suggestions going for the official game ones, now that we have a solid decision on how they actually work!
Remember, they must relate to a single level only, and the factors may only be (but can be a combination of multiple of these options):
> Number of lemmings saved
> Time taken
> Quantity used of specific skill(s)
> Quantity used of total skills
> Keeping the release rate within a certain range
Let's avoid ones that require forced skillset to use the NeoLemmix skills; but using larger quantities of skills (or more than the usual time) is fine, since Challenge Mode / Timer Mode can be used for these. Forced gimmicks can't be used for them.
Other factors can maybe be added if there's good challenges for them.
In terms of those for Lemmings Plus and Doomsday Lemmings, feel free to give suggestions there too (note that I don't plan on adding talismans to Lemmings Plus Flashbacks) but I'll be putting less weight on community-suggested ones there than I will be for the official games. I've already come up with 23 for Lemmings Plus I, but ideally I'd like to come up with two more (so that it's a round multiple of 5, as that's how many the talisman record screen can display at once).
