Here's a useful hint for those who are not clear on how to get the bitmap you want to convert to be in the format acceptable by myvgaspec.

Simply make a copy of the included example.bmp file.  Note I say to copy the file itself, not just the graphics.  Then in your copy, inside a suitable graphics program like MS Paint or Photoshop or what-not, erase all graphics and start copy-and-pasting in your own graphics, and optionally do some additional drawing as necessary.  Then just save the copy.  Since the copy started off in the correct file format, it should end up being saved in the correct format as well.

That should ensure you won't run into any errors with myvgaspec, unless there is really a bug in the program.

Many levels are missing water that goes along the bottom of the screen, which usually just serves a decorative purpose, but it makes the levels look a lot plainer. Call in the bomb squad is even missing the decorative water along the top,

That's also true in the DOS version as well, although I'd guess the DOS version did it for memory/performance reasons.  I wouldn't expect the Playstation to have such problems.

Triple Trouble has 12 builders and Steel mines of Kessel has 20 of everything,

That's also true in the DOS version (at least for Steel Mines, I don't remember off-hand about the other one), though I don't really understand why.

That being said, the Mac version is unintentionally harder.  On the original versions (Amiga, PC, Atari), there are 3 terrain areas which are traversable, but on the Mac became extra obstacles due to graphics differences.  Together with Mac's reduction to 80 lemmings out without adjust the percentage to save, and you end up with a level whose difficulty is way out of league with the rest of the game.

This makes Livin' on the edge quite difficult, although iirc the mac only has 6 builders yet the playstation has 10.

I think most versions (DOS, Amiga, SNES, etc.) also have 10.  I'll have to check the Mac version myself tonight.

...Maybe.  I guess some of the middle parts might sound slightly weird out-of-context, especially to someone who hasn't heard the music before in the proper context of the game's intro sequence.

Although I think some editing could help with that.

My main concern with the overly short MIDI is that, as you know, Cheapo has a bug whereby if the game's paused, the music won't loop when it reaches the end of the MIDI, until you unpause the game.  With your current Prince MIDI, this is almost guarantee to happen for anyone who's figuring out the level.

Any thoughts about sound effects?  I can help with those too.  (Well, it's really just a matter of capturing to WAV via DOSBox.)

Quite interesting how well the general layout of a Prince level works as a Lemmings level also, although it does take a tiny bit of time to get use to some things (like having to bash thru pillars that the Prince would've walked thru).

One suggestion:  It would be cool to replace the normal "Let's Go" sound effect (#12) or the "window opening" sound effect (#6) with that ominous "da-da-da da" chime sound that's played at the start of each P.o.P level.  There should be a few other opportunities for sound effect replacements, like falling deaths and certain trap sounds.

Oh, and although it's not a big deal and a bit of pain to do it, I personally would get rid of the words "Prince of Persia" in the background graphics of the level intro screen.

I was wondering if anyone can find an electronic version of the Lemmings 3 manual.  If not, at least a brief overview of how the game works.

I guess eventually I'll figure everything out (after all, that's how I went thru Lemmings 2), but help is appreciated too.  Thanks.

Sprite rippers rejoice!

Except we already have the means to rip sprites without waiting forever for the next version of DOSBox.

In fact, I think the Windows version of Lemmings actually comes with a bitmap that has all the relevant sprites used for playing a level (namely, all the Lemmings animation).

What would be useful though is the ability to record solutions.  This is assuming it will not degrade performance too much (depends on your machine I guess).

and then since you can't change the RR while pausing in the Genesis version, it looks like you really do need 3 diggers there.

I'm wrong.  Although you still can't change the RR while pausing in the Genesis version, I found that if you pause the game at the earliest moment allowed, then unpause and raise RR immediately, you can raise the RR high enough to allow a 2-digger solution.

It's still the case though that the Genesis version's digger seem to be subtlely different from the Mac version in behavior.  I don't know for sure yet whether the DOS version is one of the two behaviors or a distinct third.
