The readme describes exactly how to do that, as does the tutorial here. Using LemResourceBuilder to make the RES files is part of that.

If you really can't get it working (or can't understand it), send me all your data / music files and I'll put it together for you - but only if you can tell exactly what doesn't work (or what you don't understand), to make clear that you have tried to do it yourself. (Just like how with the music files, I was happy to do them for you because I could see that you'd tried yourself but couldn't quite work it out.)

Although I'd have to try it before saying for sure, at first glance having both directional selects on the same finger doesn't appeal to me...

At the moment, each seperate EXE has a seperate configuration (it's stored in their save files, which are not compatible between different player EXEs).

I don't know how much overlap there is between other skills, but from what I've heard, the Walker and Platformer are the same in NeoLemmix as they are in Lix, and the Stoner is like a... Cuber, was it? It basically turns the lemming into terrain; with one difference that has been pointed out being that the NeoLemmix ones can be used in mid-air.

The other skills (for those who aren't familiar) are Swimmer (self-explanatory), Glider (basically, "diagonal floater"), Mechanic (disables traps; permanent skill), Stacker (like the L2 one, but creates the stack in front of the lemming, rather than below it) and Cloner (duplicates the lemming, with the clone being identical except facing the opposite direction).

I've changed it to 20 for now.

That's normal. You don't have to run GoRC yourself; what matters is that it must be in the same folder as the resource builder.

GoRC does nothing unless it's supplied with certain "command line options". You don't really need to worry about these, it's a technical thing - what you do need to know is that when GoRC is needed, LemResourceBuilder will automatically run it (with the correct command line options). So, LemResourceBuilder and GoRC must be in the same folder as each other.

Okay. If it's creating those files, but not creating the RES file, then this would mean for some reason it's unable to run GoRC. You did extract GoRC into the same folder as the resource builder, right?

I'm off for a bit now, but I'll look into it more later.

If so, when exactly does this error occur? Is it immediately when you open resource builder, or only when you click one of the buttons? Does it happen on both buttons, or only on one of them? Does the resource builder create the ARC and RC files (but not the RES file), or does it not create anything?

Although I haven't looked into it, I doubt it'll be too hard to manually add such an option if need be.

The ones you've made (if any) for pre-level / post-level texts. If you haven't already created them, then yes, new text document is correct.

Pretty much, if you've got a folder where you've got the (non-toolkit) Flexi player working for your pack, you should copy all the music files from it into the "music" folder, and everything else (except the player EXE) into the "data" folder.

Mainly, yes, but also any pXXXX.txt / iXXXX.txt files as well.

Easiest way is to just extract everything in the toolkit into one folder, seperate from anything else (so not the same folder as you're using to make your game).

Then, you'll want to:

Data folder
Put all your data files in here. By default, the Data folder already contains copies of every graphic set; you can delete ones you aren't using if you want. If you're using any that aren't in there (custom ones, converted Cheapo ones, etc), make sure to add them. Pretty much, every file for your pack that isn't a music file should be in here.

Music folder
Clear out everything that's already in here (unless you're using them - if you don't have your own, you might want to leave frenzy.it and gimmick.it in here). Put all your music files in here.

After doing that, does it work? If not, can you give more details on exactly what happens (see my last post).

If it's the resource builder giving that error, it's probably not a matter of needing to update. The resource builder hasn't been changed since V1.27n-B; only the player EXE has been.

Check the following:
- Have you extracted all contents of the Flexi Toolkit into the folder with it? (in particular, is GoRC.exe in the same folder as the resource builder?)
- Are all your IT/OGG folders in a subfolder called "music"?
- Are all your other files (graphic sets, LEVELxxx.DAT, pXXXX/iXXXX.txt, etc) in a subfolder called "data"?

If so, when exactly does this error occur? Is it immediately when you open resource builder, or only when you click one of the buttons? Does it happen on both buttons, or only on one of them? Does the resource builder create the ARC and RC files (but not the RES file), or does it not create anything?

I doubt that's going to happen any time soon (though you never know!). If you would like the Master System ones, here:

Master System OGGs

The unique tracks are #13, #14, #15 and #17. #13 in particular is unique - while the other 3 are (like many Lemmings tracks) based off classical tunes*, #13 seems to be an entirely original composition for the Master System version (and, I must say, a very catchy track). If you've played Lemmings Plus I or Lemmings Plus Omega, you may recognize it as being levels #13 / #30 in the former, and levels #15 / #30 (except Mental 30 and Playtime 15) in the latter.
