Lemmings Revolution: 11/7 "Don't let them Out" just seems like 100% should be possible.

You have 49/50. If the lemming you loose is the one that has to mine/dig a hole into the water to kill the weasels, this possibly can be saved; using the miner trick where you can build while mining but leave a small hole.
normally, he will turn around and drown but (I need to try this yet) it could be possible if you build near the door he will turn around and keep building and possibly leave a gap for the weasels to go in.

^ I solved the easy version but not the hard version yet. It does look like a good candidate for backroutes.

here is another whopping folder of levels (only two are new though) Idk how easy they are. Probably easy enough. The other three are updates for Jacob's Ladder to remove backroutes, Tinker Tailor soldier lix, to make Proxima's solution the correct one, five for fighting just to add the decorative TNT to the exit.
(again, put the levels directly into your wip folder or whatever)

Also at some point in time I'd like to upload a folder of all my reject levels, maybe Proxima or someone can use them and make something out of them.

here is a folder of 4 levels (these aren't the ones I mentioned I was working on in IRC but anyway..) When you unzip the folder take the levels out into your wip folder.

you asked for it so, I made three easy levels that are good beginner puzzles. the first is an easy version of division of labor, since I thought we could use an easy level with only a few lemmings.
After debating whether to leave Division of Labor alone I decided to try and force my original solution. It just looks cooler imo.

I also updated Bippidi Boppidi boo for the basher update

-fixed the typo in Jacbo's Ladder 

[I realize something like this has already been done on other sites but I didn't see anything like it here and I wanted to go into more detail. Obviously; this is not finished.]

here's where you can compile information on the differences between all the many, many versions of Lemmings games. In this first post I will have only Lemmings 1, the original.
feel free to contribute or make corrections.
I'll do other games later if there's enough information on them
============

Amiga
-intro with balloon and mountains and music
-cursor is unique and waiting cursor is a lemming sleeping.
-menu screens are greenish/black
-background color is navy.
-you can scroll the screen at different speeds
-selecting a skill or changing the RR while paused; NOT possible.
-many levels have liquid across all or most of the bottom of the level
-max # Lemmings 100
-two player mode. One of the few version to support two mice.
-right click to invert worker/walker selection priority
-no directional priority
-brown skill bar
-when you change the RR the pitch goes up like a bottle filling up with water
-first version with a voice for the lemmings (as heard in the video in a link posted here http://www.lemmingsforums.com/index.php?topic=456.0, the original voice of the Lemmings was one of the creator's mother. (this is the only version with this voice maybe not.)
-lemmings make a sound when they fall off the bottom of the screen
-At the end of game there is a congratulations screen with DMA design team applauding sounds and portraits.


DOS
-title screen is changed
-no intro movie
-no custom cursor
-menu screens are brownish/black
-background color is black for the rest: unless mentioned background color is black
-screen only scrolls at constant speed (somewhat faster than Amiga's slowest speed)
-Max # of Lemmings reduced to 80
-music is different and re-arranged
-lemmings walk slightly (very slightly) slower
-Levels which have liquid across all or most of the bottom of the level have the liquid removed.
-sound effects changed. Lemmings don't have a voice, just SFX.
(on a side note: the sound of lemmings splatting was very similar to the sound of the drums in some songs, making it confusing to tell if lemmings were or were not dying somewhere in the level. And the song 'little doggy in the window' sounds like fart sounds)
--lemmings make NO sound when they fall off the bottom of the screen
-slight graphics changes (e.g. directional arrows in Marble are red instead of blue which they are in most other versions)
-the skills bar is green
-some new glitches present (see Lemmings glitches thread)
-no two player mode (all the rest unless noted also removed 2 player mode)
-several levels have reduced save requirements: Fun 15, Taxing 22, Mayhem 4, Mayhem 15, Mayhem 26 
-some levels have a change of skills *Proxima^
-no directional priority
-no sound for changing the RR
-no DMA congratulations screen with pictures at end game. Just a message.


Atari ST
-menus are similar to Amiga
-max # Lemmings 100
-graphics very close to Amiga (the closest of any version)
-music and sound effects are remixed, yet again. (the sound of lemmings going home sounds a lot like Mario jumping!)
-changing the RR makes noise but doesn't change pitch
-title screen similar to Amiga
-brown skill bar
-uses a different set of passwords for levels
-you had to use a joystick for player 2 in the two player game
*contributed by finlay
-game speed is slightly faster [needs verifying]
-intro same as Amiga but with no sound
- Mouse cursor is only the "Zzz" bubble of the Amiga version's cursor when something is loading.
- You can scroll the screen at different speeds too.
- You can change skills while paused by using the Z and X keys. I don't know if it's the same thing for the Amiga, but I think it is. However, you cannot change the release rate while paused and it may be painful. You also cannot pause the game using the keyboard.
- Right-click for worker/walker priority
- Lemmings are silent when they fall off the screen.
- Background colour is navy.
- At the end of game there is a congratulations screen with DMA design team applauding sounds and portraits.

ZX Spectrum
-The graphics are ridiculously insane!
see: http://www.youtube.com/watch?v=n0g1tv1gXvk
-the graphic sets are completely different and basically an approximated attempt to resemble the originals.
-there are some major changes in level design. The last level looks like a shortened/altered version of 'Watch out! Traps about'. Many levels have alterations to make them smaller and sometimes more interesting.
-there's only 60 levels. And the levels are re-arranged.
-there's no mini-map
-there's no steel
-there are no animated traps (except water).
-Sound effects are different as well as music. In the video above the same song plays throughout  the entire game, Idk if this is intentional or not.
-game play is much slower
--some embarrassing glitches caused because of the graphics (see Origins and Lemmings in that video). If that is a even a glitch at all.
-when a basher starts bashing a large chunk of terrain can be removed behind him.



Sega Master System

-Max# of Lemmings 20
-Major graphic changes. Graphics are arranged in a large grid making some levels difficult thus, they weren't included; "Save Me" is an example.
-major music/sound changes
-some level design changes mostly due to difference in graphics.
-game speed is slower



Sega Genesis
-slight graphics changes
-max # Lemmings: 100
-the overall screen size is shortened a great deal
-many levels are drastically changed due to ^
-many levels are removed and replaced with new ones and a few remakes of Oh no More Lemmings [only levels from Crazy]
-two totally new categories with mostly all new levels except one OONL remake
-game play is slightly faster
-deadly fall height difference (is it higher or lower?)
-steel works different; even more glitchy than previous versions.
http://www.youtube.com/watch?v=iipvDLK0pOU&feature=relmfu
-has two player mode
-two "hidden" test levels (see this thread http://www.lemmingsforums.com/index.php?topic=547.0



Commodore 64
coming soon!


Super Nintendo
[according to Lemmings Encyclopedia the NES version came out AFTER the Super Nintendo version ]
-max # Lemmings 100
-Level arrangement same as PC with a few exceptions. An extra rating is at the end of the game with # levels from the Genesis version.
-game lags when many lemmings present on level.
-new glitches present (possible weird builder/digger/blocker behavior)
http://www.youtube.com/watch?v=QNWt2IB8MsY

Nintendo
-Max # lemmings: 14


Phillips CD-I
http://www.youtube.com/watch?NR=1&v=0Goami6ie_E&feature=fvwp

-A CD-I like cartoon intro (familiar if you’ve seen the similar intros to games like Mario and Zelda series on CD-I)
-similar to Amiga version in music line up, graphics, skill bar etc…
-Atari ST cursor (Zzz but no sleeping lemming)
-remixed music
-by a strange coincidence; this version actually seems to have a pause in between song loop, which I mentioned incorrectly about Atari ST. And takes a while for the song to start (at least it's present in the first level the only available place to see in that video unfortunately)
-RR makes noise but doesn’t change pitch
-lemmings have a voice. I wanna say the voice is the mother from Amiga It sounds close.
-messages after completing the level are different. [e.g. “WOW, you saved every lemming. TOTALLY EXCELLENT!”]
^this is something I haven’t looked at, at all on other versions.
-codes look the same as Amiga and DOS.
-game goes slightly slower.
-Surprisingly, aside from the standard bad Phillips controller, the game doesn’t appear to suffer from the gross butcher job they did with Mario and Zelda. If I had a Phillips CD-I I would definitely get Lemmings. (Probably the only game I would get )
no info yet on controls such as directional selection and such


Sega Game Gear


Gameboy


Mac
- High-res graphics (with occasional large effects on gameplay, e.g. Mayhem 26)
- Max # of Lemmings reduced to 80
- music is very similar to Amiga *finlay
- Tricky 21 replaced with "Going Their Separate Ways" (by the way, if you have the original levels for Lix, this one is in the Genesis Tricky folder)
- fast forward
- clock runs slower, making Mayhem 16 and 27 really easy
- steel is detected more easily, with noticeable effects on some challenges (e.g. Taxing 6 100% is impossible; Crazy 1 100% is much easier)
-select skills and RR while paused
- The scrolling text on the menu has elements of humorous self-deprecation (it talks about the 'elevator music'!)
contributed by Proxima
-the design of the hell exit is different *Guy Perfect



Acorn Archimedes

- Logo splash-screens for Psygnosis and Krisalis Software (the company that made the port).
- The scrolling text on the menu has elements of humourous self-deprecation (it talks about the 'elevator music'!)
- Remixed music, including a few unique tracks.  Of the four special levels, only the music for MENACING resembles the original.
- Lemmings make a sound when they fall off the screen.
- Changing the release rate causes the pitch of its sound effect to also change, like in the Amiga version.
- Animation seems to be extremely smooth in comparison to other versions.
- Many levels have large expanses of water at the bottom, like the Amiga version.
- No two-player mode.
- No directional select.
- Background is dark blue with (mostly) white text.
- Passwords are meaningful and easier to remember (e.g. "DOUBLEDUCK" is Fun 22, and "LEMMGFINAL" is Mayhem 30).
- Release rate behaves differently (notably, a release rate of 1 spaces the lemmings out nearly twice as far compared to other versions).
- Levels closely resemble their original Amiga counterparts (e.g. "The Fast Food Kitchen" has a time limit of 2 minutes).

On an extra note, the Archimedes version of Oh No! More Lemmings has a very large array of music tracks: 26, compared to the Amiga's 6.

Windows 95
-ONML included
-no intro
-Max # Lemmings: 80
-remix of music and sound effects. songs in MIDI format.
-includes Oh No More Lemmings!.
-the same music from the Original levels is used for the ONML levels. The ONML songs are not included.
-graphics and some other general things seem to indicate it was modeled after the DOS version. (e.g. no water across the bottom of levels)
-this might be the first version with a "yippee" instead of the boing sound upon entering home.
-added "action phrases" like CLANK appear above lemmings in game
-some graphics changes (they gave it some kind of goodie-goodie treatment, removed the horns from the exit on the hell set. I'm sure this also accounts for all the 6's)
-some songs removed (March of Days, 'little doggie in the window' and songs that go with the special levels)
-some levels removed: all the 6's, all of the 'special terrain' levels, We all Fall Down Part 1
-deadly fall height lowered. Most notable on levels We all Fall Down and Steel Works. (We all fall down can be completed by doing absolutely nothing!)
   **on the version that was bundled with Lemmings Paintball, this glitch is fixed on "We All Fall down" but curiously, not on "Steel Works".
-a fast forward button
-ability to select level manually in tree system (no more codes)
-miner tunnels looks different ('steps' are more pronounced)
-direction priority selection
-no worker/walker priority selection
-some glitches are fixed and some new present (see glitches thread)
-select skills and RR while paused
-the entire screen is slightly larger than the original levels, making a small gap at the end visible in a level where terrain covers the whole level.

-unique opening animation
-graphics and music similar to Windows
-ONML included
-The music was like the Windows version but rendered in high quality and recorded as CD tracks instead of being kept as MIDI files.
*finlay


PSP
-scenic background on every level
-graphics very different. Much higher resolution/better looking and more detailed. Below is a list of a more proper name for them:
pillar - egyptian
marble - roman
crystal - chemical plant? (open to suggestion)
dirt - dirt
hellfire - hellfire
-removes some levels while adding some new ones
-lemmings walk slower
-many levels have more time to compensate for ^
-new voices for lemmings and new phrases. (e.g. lemmings say something every time I skill is assigned)

Lemmix


Lemmini
-fall height difference (lower than original?)
-fixed most of steel glitches

I don't mean to go off topic but you guys  seem to be knowledgeable about this. Can anyone recommend a good preferably, simple program for creating songs in Midi or similar format (any format will do really but you seem to know about Midi first and foremost). I've been looking for something like this for a while and haven't found much. I want something that's simple/ not complicated like Fruity-Loops and preferably inexpensive or free. Also having an interface like a piano keyboard for entering notes would be nice.

I don't know what program you guys were using to do this. Adobe Audition is a very good sound program to edit/analyze music with. It's not great for writing/creating songs though.

 . nice, GuyPerfect.  it gives me more ideas. Maybe I'll make mine in color too. might as well I guess.

Jacob's Ladder replay was great. there's a little leeway with the execution. You don't need all the climbers or floaters. (as you demonstrated). this level was inspired by AAAARRRG (obviously). It's one of my favorite levels of ONML.

just stop the bleeding is a tough one. Now I regret changing the left side and giving you that idea.

Here is the last Tseug remake (I planned on a doing a special bahser level but I'll probably make it more decorative than his). This is (imo) the easiest level in that pack but it could still elude a good player. Idk if the circus set was a good replacement but it was difficult to find good terrain to use and I wanted some variety.

follow GuyPerfect (or ccexplore) for advice on Lemmings Revolution. this game is still in the works to be playable on Windows 7. and an editor to be made for it (I can dream can't I?)

if your looking for any other lemmings games (since you just said "Lemmings") I suggest Lemmix: http://www.lemmingsforums.com/index.php?topic=414.msg9334;topicseen#msg9334

I also suggest Lemmini: http://lemmini.de/ If you need help see the "Lemmix" help thread (there's two of em) or post here again I can give you more specific instructions.
