lem os dead
namida you can rest now that this stupid ambitious mess is dead

so lemos dead

But...
I'm making Lemmings 4!
its in gamemaker and the lemmings are a bit stiff, (right now all i've got was a interisland ballistic lemissle ) but hey its getting done
(maybe i'll be the one to finish the tribes arc)

wow, that was 10 days ago I posted? It felt like yeserday... well I skimmed over the topic quickly and I don't think you've updated these two in that time??
I solved these two with the help of SQRon, The Oubliette particularly was very tough imo, but very clever solution, if it's correct. Outside the box is likely a backroute, I saved the blocker, but it felt as least partially intended, the overall jist anyway; I don't see how else to go about it... this solution does not work for the second one.

This one took a little bit of tracking down, but it originates from the new "Highlight Erased Pieces" feature, which draws eraser pieces with purple solid fill instead of a transparent overwrite.

The issue is that the rendering was checking the setting byte-by-byte, which is horrendously expensive and causes huge slowdown on any level which contains more than about 10 eraser pieces. The level in question here has many eraser pieces, which has helped to flag up this issue.

The fix is to cache the setting once per rendering cycle, and apply the cached setting. This restores the usual speed and fluidity of rendering, even for levels with many pieces.

Fixed in commit cb0c2e6.

Added xmas style to the styles folder to ensure that the included Holiday levels work. There's no need to increment the SuperLemmix version number, since no changes have been made to the program itself, and the xmas style is available from the main styles download anyway.

Ah, the xmas style was missing from the download. I've now corrected this, but here it is for anyone who already has 2.8.9 and doesn't want to download the full folder again.

(To install, unzip the attachment and add it to the "styles" folder in your SuperLemmix directory).

Whenever I attempt to load the Xmas Lemmings levels (all of them) I get an error message saying that "This level cannot be played as it doesn't have an exit!"

Truthfully this is my first attempt at using superlemmix so I suppose I might be missing something. I was able to load several other levels without issue, but all of the levels listed under Xmas 91 and Xmas 92 get this error.

edit:
This is SuperLemmix 2.8.9

What can I say? Having once stated on one of my early posts that I wasn't very good at discovering backroutes, I better change my slogan to 'If there's a backroute, I'll find it.' Just don't expect me to find your intended solution Honestly, I wouldn't even bother patching ONE 6 - no-one else would even attempt, let alone pull off, what kaywhyn did there!

ONE 2 Aquarium Deception and ONE 5 Blues here :

Alright, now I finished watching carefully all the replays from you all, and the tremendous LP by kaywhyn.

I learned a lot from the replays, and have a very fun time watching kaywhyn playing my levels. Kaywhyn, it was a joy to hear your comments, to see you falling for most of the traps I set up and struggling on all the little details I put in there to avoid nasty backroutes

As already said, you and other players overcomplicated some stuffs, I'll most certainly write a PM to give some details and intended solutions on the most complicated stuff. Also, I need to defend my NEO 5 level, which both of you backrouted and dislkiked ! 

So now comes the time for a major revamp of the ONE rank, along with some levels in the other ranks. I'll be sure to post it here when it is done.

Finally, to honor the time and effort kaywhyn and JawaJuice put in solving some levels not the intended way  , I join those levels and their crazy replays.
Those solutions will not work on the newer version of the levels to come
