It's interesting to compare
Luis's results for PSP Lemmings (played on the actual PSP version) with
our results from the NL conversions of the levels (which, I believe, are based on Luis's Lemmix conversions, although I have made small tweaks to a few levels).
Obviously, some results differences will be because of the different engines (e.g. the shredder in Level 33 requires an extra builder to build past in NL) and some might be because of inaccuracies in the conversions. However, some differences may be because only one person has attempted this challenge on the PSP levels, and it's easy for one person to miss things (e.g.
Eric's post here suggests that the digger is
not required on Level 36).
So it would be interesting to go over the PSP results and try to improve them -- and also to see whether any of the cases where the PSP result is better than the NL one are because we missed something when playing them in NL
[EDIT: Already discovered two cases where Luis caught something that we missed -- Levels 15 and 21.
And thanks to Pooty, all the remaining cases where the PSP result was an improvement on the NL result have now been confirmed on NL too!]
[EDIT 2: Also, the adding up of the PSP results was wrong on a few counts
I've taken the opportunity to correct it, taking Luis's results for the individual levels as correct for now, even though I suspect that several of them can be improved.]
