Although the original Lemmings 3D is a DOS game, the editor L3DEdit is a Windows app, and Loap is capable of loading custom levels made with it. You still need a copy of the DOS L3D game for L3DEdit to load the graphics from, but you never actually need to use DOSBox or actually run the DOS game - it's just there for the graphics files.

There was never really enough interest in Loap to justify a purpose-made editor, especially with L3DEdit already existing and being usable for the job.

1.7.6 is out! This release also includes the improvements from the unpublished 1.7.4 and 1.7.5 builds.


More fan-level evidence and a refreshed learning journey

• Recorded winning replays now support 2,153 Classic fan levels and 322 NeoLemmix levels.
• The learning journey now contains 292 lessons, including 136 fan levels from 80 packs.
• Difficulty scores use winning replay evidence. Levels without that evidence remain unscored.
• Expanded compatibility checks help distinguish source-engine differences from levels that simply lack a recorded win.

Lemmings 2 and Lemmings 3

• Verified replay coverage now includes 75 Lemmings 2 levels, plus 27 carry-over variants, and 41 Lemmings 3 levels.
• The Lemmings 3 intro movie now plays its verified DOS OPL2 music recording. Pause, resume, volume, mute and Silent settings apply.
• Both games remain Preview. More recorded wins are useful evidence, but they do not establish complete campaigns or full original-engine accuracy.
  

Music and spatial sound

• Modern music processing now reaches Adaptive DJ's MOD playback: centred percussion, a gentler stereo spread, subtle EQ and reverb.
• Switching between Modern and Faithful preserves the track position.
• Gameplay sounds follow their position relative to the camera and zoom across Classic, Lemmings 2 and Lemmings 3. Offscreen sounds become quieter.
• Lemmings 2 uses independent spatial voices, and Lemmings 3 adds builder warning sounds.

The aim is a modest uplift for headphones and larger speakers while keeping the original Amiga character. Music remains stereo; gameplay positioning is camera-relative, without head tracking. Replay audio remains mono, and Lemmings 2 does not yet have a mapped exit cheer.


A little more drama for the nuke
With HD Effects enabled, Classic and Lemmings 2 nuke countdowns briefly hollow out the music, with restrained bass supporting those wonderfully comic explosions. A little "the oxygen just left the room" before the pop. Undo restores the mix.

Home, Goal and help

• With Modern controls, H centres the entrance and G centres the goal.
  
• In Lemmings 2, G first selects Hang Glider when available. Press G again with Glider selected to centre the goal.
• Home/End remain available. Controller stick clicks provide the same camera actions: L3 for the entrance and R3 for the exit.
  
• Use / for hints and ? for controls.
  

Fresh sessions and clearer selection

• New solo and Hot Seat sessions start at the beginning of the selected campaign or playlist. Previous sessions, achievements and scores stay saved; Continue keeps its saved position.
• Hot Seat handovers stay paused until Ready, with separate retry and next-player actions after a failed run.
• Fan-level artwork follows its terrain: Floating Down! now gets its snow landscape. The HUD follows the active journey position.
• Gameplay settings offer None, Obvious and Modern selection effects across all three games. Modern adds a white outline and green halo, with support for reduced motion and reduced flashing.

Quote from: namida on October 01, 2026, 10:01:10 PMUploading backgrounds for your levels in this topic is fine. That being said - (this part is advisory, not a rule) make sure you tell people where to put them (ie: what style name they should be under), as a loose file doesn't carry that information on its own, and I expect most people won't bother if they have to look into the level file to figure out where to put the background.

OHH

ok

Hopefully one day it will be completed! I definitely want to try it out once it is in the release topic. Your style of levels looks great

I just want to reassure everyone that this pack has not been forgotten! In fact I've made a burst of progress over the last week, and the pack is now more than one-third complete!


Topaz 8 - Hell or High Water

This level, which I finished today, is one of my favourites so far. You can go for either the left or right exit, but neither is trivial, and there is a 100% talisman that is also possible with either exit! Which way will you choose?

Only few tough mode levels remain yet and always Medium 29 which are caused me real headache. I just simply cannot figured out that level, its seems most complicated level your pack. That best what i can do rightnow, i´ll overlook something. Im not give up it yet, might continue it next week.

Fort William

Its might close intention solution, but i make some variation different way

Medium 29 attempt

Best what i can make is safe all lemmings down, but i´ll still need basher or miner at end, this level are take me really long. I just stuck here and skip this level, i´ll back it again, but i cannot still figured out this. Im not goes give up it yet
