I've already figured out this one.

A few days ago I was trying to find a way to play my levels on my lemmix clone. I have finally succeeded but the way to do it is very difficult I don't have the time to write a walkthrough. I felt exhausted after I've done my hard work. My previous help topic has definitely helped in this situation. http://www.lemmingsforums.com/Smileys/lemmings/smiley.gif" alt=":)" title="Smiley" class="smiley" />

No, sorry Dullstar. I don't have Custom Lemmings. I have the two Lemmixes (The Editor and the game) instead.

I removed the post...  now allow me to explain here.

The reason I suggest Customised Lemmings is because it can easily be downloaded from the Lemmings Archive, or am I mistaken?  Or, if you want something better, you could download ccexplore's hack of DOS lemmings, which is basically an improved Customised Lemmings.  It's on the file portal, find it on the forums.

I'm sorry that Lemmix doesn't work on WINE, but Dullstar, consider that minimac94 may have perfectly valid reason to not want to use Customize Lemmings.  For example, consider the replay and fast forward features in Lemmix.

Anyway, I would answer minimac94's question, except I don't know enough about what's not working for him right now.  Can you at least open your levelpaks in Lemmix?  You should at least be able to do that.  When you go to "Open..." in the "File" menu, at the window that pops up, Under "Files of Type", select "DOS Levelpack file (*.dat)".  The window will now list .dat files, browse to your levelpak file and select it for opening.

An "Edit DOS Levelpack" window should now pop up, listing all the levels in that levelpack.  Right-click on the window and select "Change Viewer Style..." in the popup menu.  A "Select Style" window will pop up, select "Custom Lemmings" and click OK.

You can go to individual levels by clicking on the level in the "Edit DOS Levelpack" window, and play them by pressing F2.  Hope this helps.

Don't worry, I've done it at last with a different way of doing it.

Sorry forgot to get back to you on this, but the CSTM.DAT file is part of Customized Lemmings.  I forgot that you need all the files from the game to actually use Lemmix.

(And I must say I'm surprised that you didn't lock this thread!)
