Thanks Guigui! Would love to play it at some point, maybe kaywhyn could LP it one day!

Hello Lemmings community,

JawaJuice and I are happy to present our collaboration level pack Reverse Lemmings: Megadrive.

Following in the footsteps of Colorful Arty and WillLem, we took the 60 levels from the Present and Sunsoft ranks in the 1992 Sega Megadrive version of the game, swapped hatch and exit, and tried our best to make fun and interesting levels from there. We made a point to not modify the levels' layouts, though solutions are of course completely different from the original and may use all skills available in NeoLemmix.
 
We would describe the general difficulty of the pack as Medium - Hard, though this may be judged better by you, our fellow community members.
Be aware though, as in Colorful Arty's pack, "the difficulty is all over the place!" There is no sense of a progressive difficulty curve and you can find open-ended X-of-everything levels next to stupid hard levels with minimal skillsets. JawaJuice reversed the even-numbered levels and I reversed the odd-numbered levels, so you know exactly who to take your grievances to if something makes no sense!

We playtested each other's levels extensively and hope they are as solid as they can be, but we're still expecting backroutes and unanticipated solutions. Do not hesitate to give any feedback or let us know if any hints are required. For a couple of levels, we actually had Armani and IchoTolot do some additional playtesting - thanks to them again for that!

We would also like to thank GigaLem for letting us use some graphical assets from his own packs, specifically the menu scroller.

The pack and its necessary style are joined in a single .zip file at the bottom of this post. Extract in your main NeoLemmix folder (levels and styles sub-folders), and it should all fall into place!

Attached to the levels is an eclectic selection of music, all chosen carefully by JawaJuice and I to fit the mood and titles of the levels. Download the music tracks from the following link and extract in your main NeoLemmix directory again (music sub-folder).
Note that if you don't want to, it is not mandatory to login with Google or such to access the download, just click the download icon and look for the "continue with download only" option:

Finally here are screenshots of four levels - you may recognize some from the original Megadrive game.

We hope you will have a good time playing our pack

Look at the lateral box cover art of Lemmings 2 in Acorn Archimedes. It seems they are unique levels, or at least, I have never seen them before.

After helping people convert old levels and levels from other engines to NeoLemmix for years now, I thought it would be nice to have a one-click tool that can convert levels with various formats to .nxlv.


Anything to NXLV! (download link below)


How to Use

Drag and drop the file(s) or folder you want to convert, onto anything2nxlv.exe.
That's it.
or.. run anything2nxlv.exe directly and follow the command prompts on-screen.


Supported formats

.nxlv (just cleanse)
.lvl (Lemmix, old format NL, DOS, WinLemm(not WinLems or Winlemms))
.ini (Lemmini, SuperLemmini(too))
.lev (Lemmins)
.rlv (RetroLemmini)
.nxp (old format NeoLemmix)
.dat (provided that it contains levels in one of the formats above)


Requirement

Requires NET Framework 4.0 or higher.
You can ignore this if you're using Windows. It's pre-installed by default.


Notes

Due to differences in some objects' sizes, animation frame counts and trigger area sizes or positions, etc.. between engines(styles), the converted level may occasionally differ from the original by a few pixels.
Levels using styles that do not exist in NeoLemmix will not convert properly for obvious reason. In these cases, missing elements will be replaced by a default_fallback image. You can check replaced elements in Conversion Report.txt located inside the output folder iff there are any

Okay i´ll quite ready this pack rightknow.   I´ll Give up Scando 3 Strufcture of Matter. I´ll might put it more efforts only if i got some tips and hints. That what i tries here its won´t work, but its only unique looking trick which might are some idea if i have more skills. Just no way pass it tool sets like this. My knowledge about neolemmings is not enought here.

Also will give up Impero 10. No any motivation play this level. Too messy, multitaks and confused everywhere. Though i did know this idea here. Its pretty crystally clear. This execution here is just turn off things for me. I am sorry about it.

Might still put some more efforts Impero 4 & Impero 18 yet.

Impero 4 is so damn close rightknow. Put it another 3 hours efforts with this morning and goes close. Fixed few things over previous attempt yesterday.

Impero 4

Its only requires extra basher, but i really cannot figured out any single place where i can let any more bashers remain. But guess my solution contains a lot intention elements, because i got those millions setups work barely here

Impero 18 is another mega messy level which give me some ideas, but not good enough executions. Main Idea seems pretty crystally clear. But finishing touches need some extra efforts.

Let post my best Impero 4 best attempt. I´ll also post this trick idea Scando 3. That best what i can make this level and looking this board anymore not help me out here.   

Scando 3

Bomb those roofs let climber walk through this area. Real trouble is 3 builder & 4 climber. Its seems theory possible with few more skills

Might moved play other levels. Crane did some new levels spend testing. Might focus look those next. How ever that was great pack. Liked most those levels a lot.

EDIT***************************************************************
Impero 4 Completed      That was very genius level.

Shelf Controlls

Yes yeah my good attempt need just this long miner at end and its let me skip this basher. Yes this is sure intention solution, just test this out, just look my best attempt solution little bit more again and i figured out it quickly here.

EDIT 2*****************************************
Impero 18 Completed 

False Happinnes

Interesting idea. I´ll overlook this quite bit first. I think this is intention solution

Two level remain. Scando 3 & Impero 10. Like already told Scando 3 just are that weird and Impero 10 no my favorite ones. Let look Impero 10 is there any clear solution. Im not really care work blind with those heck group.s

i find really funny how the last song used for the game comes from a psychological horror game  (A.K.A DDLC)

Quote from: Baldem1990 on October 14, 2025, 10:20:17 PMThe DOS CD music is here! Includes all level musics and special graphics levels: https://drive.google.com/file/d/1_K4OXEq1azBmWUqNE55JLGmx9YozFs11/view?usp=drive_link

the link doesn't works for me

(THIS IS AND OPINION, DON'T HARASS OPINIONS)

hey i know im late however some songs are good! and others bad...

many of these tracks i had to compare them to their pc-engine versions

and i gotta say... pc-engine wins most of the time... idk why does forest green sounds bad?

the special fl studio versions sound kinda off

i don't know...

the Doggie song was way more creative here

but in conlcusion...

the pc-engine port is slightly better but you know... both are good in their own ways

Alright, I have publised a 0.1.0 release with binaries for MacOS, Windows and Linux here: https://github.com/DirtyHairy/rustlings/releases/tag/0.1.0

Just dump the binary next to the DOS data files and launch it (or point it to the data directory from the command line). All levels should be fully playable, but there is not detection of end conditions yet, the level continues to run when the last lemming is gone (or time is up) until you switch to another level.

• Page up / down to switch levels
• Left / right to scroll, hold shift to scroll fast. In fullscreen you can also move the mouse to the edges to scroll.
• p for pause
• + / - to adjust release rate
• 1 - 8 to switch skill
• hold shift to emulate holding the right mouse button on MacOS
• ctrl/cmd enter to toggle fullscreen
• ctrl/cmd q to quit

In case you try it: have fun!
