Possibility of a Method to Edit Amiga Lemmings?

Dullstar · July 10, 2009, 08:10:51 AM

Might a level editor be made for the Amiga lemmings or at least something that can be used to put levels back into the game (unless of course I'm just trying to use the wrong files and don't realize it)?

Your best bet right now is to just use Lemmix, and then see if your emulator has ability to do file transfers between files on your PC and the files in the simulated Amiga disks.

I imagine there wouldn't be a difference between the hard drive version and the disk version level storage method? Or am I mistaken?

Probably should of noted that I have the hard drive version. At least, I'm pretty sure, considering I don't load floppy disk images on WinUAE

EDIT: Poorly worded. I do load disk images for most games, but Lemmings isn't one of them. Of course, considering I currently only have three games...

The hard disk version is good. I'm not even sure if the floppy version you can easily transfer files to/from it, since the floppy might use a custom format. (It's a custom floppy formating that doomed Mike from using his official Amiga level editor from his old disc, for example.)

Anyway, I haven't tried any of this myself, so take my suggestion with a grain of salt.

The problem is, none of the files have file extensions, so I can't be sure if they're even compatible with DOS lemmings in any way whatsoever.

However, like I said, it *might* be possible for him to read it in an Amiga or an emulator (though maybe not)

Extensions mean nothing. I could rename an MP3 to .bmp and it would still be an MP3.

Just pull some of the files out and try loading them with Lemmix. Maybe something good will happen.

Dullstar · July 11, 2009, 09:19:31 PM

Yeah, suppose I could have tried a different file. Or maybe notepad could be used to compare and see which one looks as much like a file in Lemmix. I may have opened the wrong file in Lemmix, I suppose. Could try a different file.

Didn't we have someone who extracted the levels from the Amiga version?

Yes, I did; http://camanis.net/lemmings/files/rips/levels/" class="bbc_link" target="_blank">they're here.

You'd have to reverse-engineer the compression format used on the Amiga levels. There's only a decompressor available, no compressor.

But you don't need to compress it exactly the way the official game does, as long as the compressor's output is compatible with the decompression used in the game.

Dullstar · October 08, 2009, 03:03:07 AM

I guess I'll have to write my own editor, at this rate.

I'm pretty sure they don't... here's an http://www.mediafire.com/?n4ywwmn4mrz" class="bbc_link" target="_blank">Amiga Lemmings hard-disk install if you wish to try it yourself.

So Mindless, how exactly did you extract the levels from the Amiga version? It's not like the game comes with an accompanying decompressor program, does it? Did someone actually write a Amiga-specific decompression program or something?

I haven't used WinUAE in a while but when I have a chance, I'll definitely take a look and see. It seems pretty unlikely to me though that they would invent two separate compression formats, one for DOS and another for Amiga.

Dullstar · October 09, 2009, 03:58:35 AM

Well, someone with expertise could try and figure it out...
ccexplore? After all, look at all you did.
