Following my series of playing old small packs, I cleared the Lemmings Migration pack by Nessy.

Wow what an amazing pack, especially for a first one if I understand correctly.

All levels are enjoyable, difficulty is very progressive and the Migraine levels are indeed very hard as advertised.
I had many amazing moments when the solutions to them finally came to me.

I think I may have some unintended solutions here and there, for instance :

Spoiler

Migraine 5 We're Coming Home : I have a climber left, did not find what to do with it. Setting up the digger stairs and freeing the crowd at the end in time with the suicidal basher was very hard. So I think I'm missing something with this extra climber

Many thanks to Nessy for the pack, hope we'll see you sometime around on the forum. When my fear of large pack is gone, I'll certainly try Destination.

I'm making some progress in the pack.

Currently at level 18 Reaper Work. The level looks doable at first sight, until you realize that you will definitely need the zombie ! It is also a builderless level, so I guess kaywhyn would like it if he tries it.

I could not clear 11 Trouble In The Art Gallery : no idea how to isolate a worker yet.
I could not clear 12 Lock Down for the same reason. Maybe yet another trick with builder and stacker that I dont know ?

Level 8 Cunning Plan I thought was brilliant.

Spoiler

I used the single miner to destroy terrain both under and above him.

Level 14 Escape Chute, I'm not sure I have intended solution because I have many skills left.

Spoiler

I used a basher canceled with a blocker in the central triangle.

Level 15 Super Lemming Adventure was super fun to solve with this Super Lemming ! I did not have courage to start again for the talismans though, sorry.

Level 17 Everyone's A Harder Nut was very nice too.

Spoiler

Typical exemple of taking the long way with the pioneer to save the "crowd"

Levels 6, 7, 9, 10, 16 all require very precise skill assignment. Solution is not very hard to guess but damn is it hard to set up correctly ! Especially in 7 and 16. Also special mention to the hidden cameleon somewhere ! You think the level is clear, but it is not ... at all 

I would like to make some levels for this, too! Would be fun. I'm getting better at making more difficult levels. Count me in!

I've attached an updated version of namida's .nxp (download link found on the previous page, 7) of the pack for v1.43 NL with the following changes:

- Corrected the Frenzy 9 - Fall Guy talisman to unlock the correct secret level. It was unlocking the wrong one.

- Moved the eraser piece on Pain 22 - Herculems down a pixel. The level was unsolvable otherwise with what seems to have been changed bomber mechanics. Interestingly enough, this level is fine in mobius' Flexible NeoLemmix Player version (in the OP) and hence doesn't need the eraser piece moved for that one.

Remember that you would need the 1.43n-F NL player to load this .nxp file. You can download this NL player here:

https://www.neolemmix.com/?page=download_list&program=16

Simply extract both the NL player and the .nxp file somewhere to your hard drive, double-click the NL player, and browse to the location where you extracted the .nxp file, and double click the .nxp file to load the pack.

The NL player v1.43n-F file is also attached here. I've also attached both the .nxp and the NL player v1.43n-F files in the OP for convenience and so that both versions of the pack and everything are in one place

Ok, after conversing with Turrican on the Discord, he doesn't have the Lemmix version of the RotL pack anymore, but he tells me that all the levels in the beta Lemmix version were all the same ones as the Lemmini ones, including the ones in the Bonus rank. Most of these Bonus levels wouldn't work in Lemmix anyway due to plenty of Lemmini exclusive glitches not working on Lemmix and hence would need to be replaced with levels, perhaps with a Lemmix exclusive glitch, instead. He also says plenty of the levels in the beta Lemmix version had steel problems, and indeed that seems to be the case, reading through this topic and seeing some users posting about steel issues.

So, just the Lemmini version of the RotL pack should suffice for the time being. Perhaps the topic title and OP description can be changed for to reflect this?

On the other hand, most of the levels should be available on the Lemmings Level Database and hence if one wants the Dos/Lemmix experience of playing the levels there's that. One problem with this is that the levels there might not necessarily be the most up-to-date version in terms of backroute fixes that the corresponding Lemmini level received. However, I just remembered that the older NL editors have a mass convert feature that allows one to get .lvl files of the Lemmini levels

Even with that, it would still be a lot of work to do, whether or not one takes the levels from the LLD or via the mass convert feature, though the latter is of course far less work in terms of getting the actual .lvl files. Even moreso if backroute fixing in either approach and hence it would be way too much just to maintain an old version of the pack. So, if a Lemmix version of the RotL Lemmini pack is ever recreated, the way to go about this would just to leave the levels be, even if there are still backroutes. Most of the levels exist in the New Formats NL version of RotL or in the RotL Outtakes and hence backroute fixes should be applied to those instead. I certainly plan to take up updating the New Formats NL RotL v4.0 of the pack sometime in the future  

I found a version of the Lemmix copy from 2015, I believe this is the oldest one I have. I don't remember much from this and I think namida, and possibly other people also helped convert this and maintain it, so I don't really know many details about it (compared to the Lemmini version, which I don't remember much of that either just because it was so long ago)

In 2018, I filed against Lix #334 Networked Singleplayer a.k.a. girlfriend mode and it's still unimplemented.

The idea is to solve vanilla singleplayer levels together. Transmit all pauses/rewinds/steps/... over the network, in addition to how Lix already transmits skill assignments. Transmit mouse location, or at least the air clicks. You can voicechat "I want to build from here", then move the mouse, "to here". When it supports several players pausing/rewinding/..., it will trivially support one player with spectators.

I think it's the fundamental mode of co-op. All existing singleplayer levels will be instantly available in girlfriend mode.

I'd love to get involved:)

I had an idea today whilst playing through Revenge of the Lemmings and just wanted to make a note of it here.

A new community collaboration pack called Lemmings Assemble. That's as far as I've got with it. I'll add more later pending discusson with Eric on Discord.

Quote from: GigaLem on March 25, 2026, 04:01:50 AMI hate that I feeling I announced Millas being back in progress too soon when Ideas dried up for me.
This month (or year) has left me drained I have finished up a video project that was meant to have been finished up months ago and now I've been very tired lately. I've sketched an idea for a level revision but I feel full hesitantcy trying to open up NLE again to make it. and I feel frustrated because I want to make progress on things but the moment I sit down I feel extra tired.

I know that feeling. Normal advice is to not put pressure on yourself with this, it is just a game after all. Ideas and will to realize will come when they do, and will be better if not forced out of a tired brain.
In the meantime, go and play Portal if you have not already !
