All of the British people and members of the Lemmings Forums will celebrate on the 35th anniversary of Lemmings on Valentine's Day (Februrary 14) 2026. Here are my fictional concepts on Lemmings mods and ports.

Lemmings for Windows 95: Director's Cut
Modified port of Windows 95 to modern PCs running Windows. Contains fixed errors (not counting the soundtrack), added "We all fall down" (Fun), "All the 6's....." and bonus levels, raised lemming capicity to 100, fixes instant fast forward bug on modern machines, MIDI conversion of DOS CD music (as known as the "Canadian Music'; plus copyrighted tracks known as "How Much is That Doggie In the Window" and "Forest Green"), fixed one-sound capicity.

Lemmings Paintball for Scratch 3.0
MIDI soundtrack recreated in FL Studio, online cloud play (user required), servers created for UK (Server 0), USA (Server 1), and Japan (remixed, Server 2), fullscreen game recreation from 480p to 720p (anti-aliased, 4:3 resolution), with help from famous Scratchers "griffpatch" and "GarboMuffin" (creator of TurboWarp, a Scratch extension engine), featured on the "Featured Projects" row in the Scratch index page (Server 0 the most popular, Server 2 behind), and added to online cloud gaming list in Scratch Addons.

Lemmings in Russia
Tribute to USSR and Russia by Russian Lemmings fan who migrated during the Russo-Ukrainian war to USA, soundtrack consisted of Russian folk, classic and 1990 Russian popular culture (seven soundtracks from Russian J2ME Lemmings were added), tilesets Moscow, Cuba (tropical), Siberia, Russian Woods, Russian Construction, Russian Old Times, and Russian 1970s, game in Russian and English, ports to Amiga, DOS (Easter egg leads to DOS CD version of Lemmings in Russia (with unique soundtrack called the "Russian Music" made in FL Studio)), Windows 95, and NeoLemmix.

Quote from: geoo on December 28, 2025, 10:06:23 PMkaywhyn, I watched your LP for Stroke at Retirement Age, and you basically had all the skill placements down after 20 minutes. Really interesting to see that the hard part was realizing that this works if only you change the timing. And similarly interesting to know that you had a hard time with Merge Sort. For Lix I actually made a small level pack exploring these flow control ideas if you're curious. It ships with the latest Lix release.

Yea, I definitely plan to take a look at your Lix pack sometime I'll let you know when I am. I've already played two levels from it, which were nominations for LOTY2024 earlier this year (I'm guessing Simon nominated them?). They are Roots of Life and Just Mine.

Also completely unrelated, but I also uploaded solutions to your geooPkG custom Dos/Lemmix pack from about 1-2 months ago:

QuoteBack in the early days I had similar trouble with tseug's Oh No, Not Again (is that in RotL as well?); it took me 4 years to solve that as my intuition for how the lemmings moved was completely off and I never thought feasible what ended up being the solution.

I checked and nah, Oh No, Not Again isn't in the RotL v4.0 New Formats NL pack. It is, however, the final level of the Armageddon rank of the Lemmini version of RotL that mobius put together all those years ago, as well as in some earlier NL versions of the pack. That is fascinating to read that it took you 4 years to get the level solved. I didn't think it was that difficult, though I do find it amusing as the final level of the Lemmini version of RotL, when it's nowhere near the hardest level of the main part of the pack.

Speaking of tseug, I also finally solved all of their 1tseug Dos/Lemmix pack recently. Woo-wee, quite a difficult pack, but I finally managed it all after starting it quite sometime ago but didn't get very far with it back then!

so i made this https://youtube.com/shorts/zZ-t_7ZYtnU?feature=share (not my main channel btw)
why the heck did i make this
i hope you like it since i wasted half my life on l4 switching engines just to make whatever this is
 

Progress was slow during the past weeks due to familiary obligations, but I still somehow managed to solve "Lemmings Faithful" just before the end of the year.
It was a good decision to leave my well-worn paths for this pack and tried to attack the talismans. I still think the talisman-solutions should be the "real" solutions as only they show the beauty of most of the levels.

My favourite rank is clearly the final one, "Treacherous". It's also the most difficult one and contains the best levels in my opinion. I especially liked Treacherous 4,8,9 and 10. Another candidate for the best level is Simple 8, I also really like Safe 5 and Tricky 1. While I enjoyed the latter one, I think that Tricky is the weakest rank.

Finally I have to praise the tilesets again. They are all great, my favourites are probably "Lush" and "Hoard".

Quote from: JawaJuice on December 25, 2025, 09:26:07 PMAre you purely focused on Lix now, @geeo? I haven't seen your levels crop up for a while in NL LDCs (although to be fair, aside from #33, I've only played up to about 15 - got side-tracked playtesting various packs).

I've never actually designed a NeoLemmix level (as far as I remember). The early contests were for Lemmix (and the "no glitches" rule was already a novelty), and in later contests I submitted Lix levels. The whole NeoLemmix scene passed by me. I migrated to Linux around 2014, generally became less active and with NeoLemmix not really working on my computer the little time I spent on lemmings was for Lix. Nowadays NeoLemmix runs reasonably well in Wine (not sure about the editor), so every now and then I try to at least look at the contest submissions.

I appreciate mobius (and probably occasionally other people) remaking some of my levels for NeoLemmix though so that the NeoLemmix community also get to play them. I wasn't particularly aware of this until kaywhyn pointed me to Revenge of the Lemmings just now. Thanks for that!
I was just looking at the level list and there are some levels attributed to me that I don't even remember creating, probably from the Cheapo days. I think that'll give me the chance to solve some of my own levels from zero, which I guess is not something one often gets an opportunity to do. I should definitely play this at some point.

JawaJuice, I'm surprised timing the basher was an issue as you can release it pretty much whenever you want and just savestate back if it doesn't work. I guess if your setup in the rest of the level isn't ideal then the basher timing becomes more difficult than it should be.

When I linked this topic, I was looking at the sticky topics in Level Design, which has Lemmings games, editors and setting everything up as a crosspost to this topic. I didn't even realize that this topic has a different title.

This is a bit of a mess.

In Lemmings Main, we have How to play Lemmings (1991) on a modern PC and How to play and create custom levels. I think this is a sensible choice (except that maybe we want to include other lemmings games in the first topic as well). At the same time, it makes sense to cross-post these in Help & Guides and at least the latter one in Level Design.

In Level Design, we have Lemmings games, editors and setting everything up which serves the same purpose as How to play and create custom levels but instead points to this topic. I think we should update the latter to include some additional information from this topic (maybe with outdated engines hidden in a collapsible tag or linking to this topic), and archive or update this topic (it has seen some updates in 2022, but is still not up to date).

In Help & Guides we have a whole load of sticky topics: This topic, one each for how to run L2/L3/L3D/Revolution, and Playing Lemmings 2 without L2-FIX (which I think can be unstickied and linked in the How to play L2 topic) and .lvl and .dat: How to play and edit (which I think can be unstickied and referenced by How to play and create custom levels. I'd suggest to update How to play Lemmings (1991) on a modern PC to include links to the corresponding topics for L2/L3/L3D/Revolution, change the title and also crosspost it in Help & Guides.

Thank you very much for solving this issue, I'll wait till the next update.

Quote from: WillLem on December 28, 2025, 10:09:45 AMThe levels in Lemmings Plus I that were broken by the styles updates didn't use the exit top (the animated part), which happened to represent the top-left part of the exit in the styles used by these levels. This is a very unusual design choice, and the reason for the reported issue.

Okay, that lifts all of my worries. All the L1 and ONML DOS levels use exit tops and exit bottoms together. And when you replace tops by full exits (a tile that combines the old top with the old bottom), you're fine.

AFAIK, only one DMA level, Division Bell in Holiday Lemmings, ever uses an exit bottom without its exit top. It's the left-hand exit. The right-hand exit is correctly put together with a top and bottom, and you can only ever win within the time limit by going to the right-hand exit anyway.

Since you comb through the affected levels by hand, with a team even, and fix what you find, it's fine. The alternative would have been to generate the full exit from the old exit bottom, not from the old exit top.

Quote from: Simon on December 28, 2025, 05:19:27 AMYou have a style incompatibility in both directions: Can't play old content in new RetroLemmini, can't play new content in earlier Lemmini.

Despite the strong wording of the linked post, it's really more of an advisory than an outright incompatibility. A couple of us are currently checking existing levels; so far, only a small handful are affected. The vast majority of levels work as expected following the update.

RetroLemmini levels that make use of the new, single exit graphic unfortunately won't be compatible as-is in older versions, but this is an acceptable trade-off; a single image for the exit is something that should have been in place from the start.

Nonetheless, in either direction, the "mods" system can be used to ensure compatibility if push comes to shove, and if the user doesn't want to update the styles.

Quote from: Simon on December 28, 2025, 05:19:27 AMCan you even recommend all those RetroLemmini, SuperlemminiToo, ..., to play Lemmings 1 and ONML anymore? You instruct to install the DMA L1/ONML pack and say nothing about the style incompatibility.

There's nothing to say regarding these levels. Care was taken to ensure that the correct image was replaced for each style (i.e. whichever image represents the top-left part of the exit, be it the main part or the animated part).

The levels in Lemmings Plus I that were broken by the styles updates didn't use the exit top (the animated part), which happened to represent the top-left part of the exit in the styles used by these levels. This is a very unusual design choice, and the reason for the reported issue.

Since all of the L1 and ONML levels use both parts of the exit, they are completely unaffected by the styles update. So, we can continue to recommend RetroLemmini for playing these packs.

---

EDIT: It would be possible to add the deprecated pieces back in to the styles to ensure cross-compatibility, but I'm only happy to do this if it proves to be a major problem. So far, we've fixed the small handful of existing levels that have been affected, and any content made since the release of RetroLemmini should ideally be played in the most up-to-date version available anyway.

Quote from: WillLem on December 28, 2025, 01:34:11 AMThe following levels have been fixed for compatibility with RetroLemmini 2.4 (specifically, styles revision 2.2):

PLEASE NOTE: Following this update, this pack is no longer compatible with SuperLemmini or SuperLemminiToo. Please continue to use V1.2 for those engines.

You have a style incompatibility in both directions: Can't play old content in new RetroLemmini, can't play new content in earlier Lemmini.

Can you even recommend all those RetroLemmini, SuperlemminiToo, ..., to play Lemmings 1 and ONML anymore? You instruct to install the DMA L1/ONML pack and say nothing about the style incompatibility.
