Right, a few days ago WillLem asked for my input on if things sound good on what he's proposed in regards to the general development of this pack being something that will come of it. Here's what I honestly think:

I think what's been put forth so far are excellent suggestions and valid points from which to base development decisions on for when work does get underway, especially on a long overdue update for the v4.0 of the RotL pack. Before any work goes towards Lemmings Assemble, however, I think it's best if WillLem first focuses on the two mini-packs of 120 levels each first. After those are done and maybe deciding on some more things on the third pack, then see if you still feel like it's best to collaborate our efforts on updating the V4.0 New Formats Nl version of RotL for Lemmings Assemble to closely resemble and follow. I certainly don't mind and would agree here that we should, but I believe you also mentioned that people who want to contribute to the Lemmings Assemble pack are free to create levels for it. If so, it does sound like it'll be its own project independent of the New Formats NL version of RotL. Again, see if you still feel like it's best to collaborate our efforts between v4.0 RotL and Lemmings Assemble after you do and finish the first two packs of 120 levels each first Level creation for Lemmings Assemble might not even be necessary, given the amount of unique levels Proxima was able to find after comparing the levels in the v2.0 and v4.0 of the RotL packs and compiling the results in an Excel spreadsheet being way more than enough!

As has been pointed out, RotL is a very huge undertaking for anyone alone, especially given the current sizes of all of them being over 200 levels each. A lot of collaboration is needed among several people so that RotL is as good as it can be. Of course, it won't always be possible to come to a consensus on everything, but we do what we can!

Ultimately, just remember that there's no rush or even any real urgency to do this, especially as the v4.0 RotL pack is at least completely playable, though possibly way too huge on the number of levels. I agree with Proxima that doing nothing with it anymore isn't the way to go, as it's been in need of a long overdue update for a while now. Even though the level ordering is far better than in earlier versions of the pack on different formats of NL and even the Lemmini version, the very first RotL pack there is available, it's still far from perfect on that. Not only that, backroutes need to be fixed, deciding what levels to cut, if any, and what their replacement should be, etc.

To be clear, I think this project that WillLem proposed is a great idea. I just think it's best to focus on a few things at a time so as not to overwhelm oneself, though this is likely just me talking, as I personally like taking my time and baby steps with anything I do

Brief description included in the OP in this topic. See readme file for Rearranged pack for complete details as the changelog is huge.

Posting an update to both of eric's SuperLemmini conversions of Revenge of the Lemmings that removes the unnecessary extra levels/files, in particular the ones from the Extra ranks and duplicate music tracks, in order to reduce pack size for the Rearranged pack. Changelog is especially huge for it, so see the readme file I included for that

Also link for the music pack for the Rearranged pack, as it's too large to include in the attachment:

https://www.dropbox.com/scl/fi/x6lfq0jhbj2z9aakxrfgy/Revenge-of-the-Lemmings-Rearranged-music.rar?rlkey=nm1bq8c8yhxm45qlcs0ibs709&st=8pwp07rs&dl=1

All of the music for the SuperLemmini conversion of the Lemmini RotL (the non-rearranged one) are included in the attachment

Rearranged replays have been updated to include only my replays for levels that I added, used the condensed NL level map size, the former secret levels of the Extra 1 rank that moved to the end of the main ranks, and any levels that changed to match the RotL v2.0 NL version of the level.

Updated the link in the OP to redirect to this post. Will likely put the levels of the Extra ranks into the RotL Outtakes for NL since they're levels that can be found in the other conversion pack, i.e, the extra levels of RotL can be found in the Rearranged conversion pack and vice versa

Quote from: WillLem on March 26, 2026, 09:46:18 PMAh OK, cool. Well, I've been thinking that maybe the RetroLemmini version of ROTL could be split into 3 packs. There are currently 270 levels across 10 ratings, which just seems excessive tbh. We could easily split this into 2 packs of 120 each (ROTL I and II, each with 4 ratings of 30 levels), and then have 30 levels left over to start Lemmings Assemble (which would essentially then be "ROTL III"). We'd then ave a ROTL trilogy, which seems a much better way to maintain these packs going forward.

Indeed, it really confuses me why there's an Extra rank in eric's SuperLemmini Revenge of the Lemmings. As this is simply a conversion of the Lemmini RotL pack, IMO the 6 main ranks are sufficient. I don't see the point of the Extra rank whatsoever and think that it can simply be removed. From a quick glance of the Extra rank, those seem to be levels from Revenge of the Lemmings v2.0, aka, the Very Old Formats NL version of the pack. I really don't see the point of mixing the Lemmini levels with the v1.43n-F NL RotL levels when the latter already exists as a separate RotL pack anyway There's about 76 levels in just that rank alone! Can definitely remove the fluff and bloat to reduce the pack file size, especially when combining it with the music pack.

Similarly, as eric's Revenge of the Lemmings Rearranged is a conversion of RotL v2.0, aka, the pack in this topic, the 19 levels that are in the first Extra rank of Revenge of the Lemmings Rearranged can simply go into the main ranks themselves. They are secret levels in the Very Old Formats NL version of the pack, but since SuperLemmini doesn't have them, I think they can just go into the main ranks. Yes, it will cause the ranks to have different amounts of levels instead of them all having 30 like it is currently, but I don't think that's a big deal, considering the v2.0 has differing amounts of levels in the ranks when including the secret levels in each of the ranks

The other two Extra ranks, once again, I don't see the point in them, as they're levels that are already in the Lemmini version of RotL. RotL v2.0 for Very Old Formats NL is a completely separate level pack from the RotL Lemmini version and hence I don't see the point of mixing in the Lemmini levels that aren't found in the former with it by putting them in both the second and third Extra ranks as eric has done. Sure, this time it's only about 40 or so extra levels, but if there's an opportunity to remove unnecessary files in them, that should be done.
 

QuoteIf your intention is to maintain the SuperLemmini version only, then of course you don't need to do anything regarding the proposed RetroLemmini version. But, it might be good to have your involvement with this as well.

Yea, I'll certainly be more than happy to help you and eric out with anything that needs doing for the RetroLemmini version of RotL. I'm generally called for for my level solving skills, so I can certainly help out on that front to ensure all levels can be solved, especially the higher ranked ones, but anything else I'll try and assist in any way possible, if and whenever I'm able to.

I'm going to make it clear that I'm not and won't be maintaining eric's SuperLemmini conversions of RotL. I'll leave that up to him if he wants to do so. I'm simply assisting by tidying up and removing all the excess fluff and bloat files that don't need to be there in the pack download in order to reduce the pack size. As previously mentioned, a lot of the music tracks are duplicates. After removing the duplicates, the number of .ogg tracks has been reduced from 48 to just 12! The rest are .mod files which don't contribute as much to the file size as the .ogg music tracks. Not only that, the number of music tracks has been greatly reduced from well over 100 to just about 66 or so!

In any case, I think once I post an update for the SuperLemmini RotL packs, they can pretty much be considered done. Unless there are problems that are spotted and in need of fixing, of course.

Quote from: Mobiethian on March 26, 2026, 09:50:15 PMI want to learn it is what I had in mind.

Keep in mind the pack is just an idea floating around for now and that it may or may not happen

Interesting idea. I'll consider contributing some levels, though I likely won't contribute much, especially as have my Lemmings Memories pack currently in-development

Quote from: WillLem on March 25, 2026, 02:07:34 PMI had an idea today whilst playing through Revenge of the Lemmings and just wanted to make a note of it here.

Speaking of RotL, I'm currently sorting out and tidying up eric's SuperLemmini conversion of the pack. In particular, there were a lot of duplicate music tracks and hence were removed in order to reduce the file size of the music pack. Also, as I was going through the levels to make sure I had the correct music playing on them to match with RotL v2.0 for Very Old Formats NL, I found some incorrect level stats. Will probably post an updated version soon in the Lemmini Level Packs Archive topic

Quote from: Mobiethian on March 26, 2026, 03:07:55 PMI would like to make some levels for this, too! Would be fun. I'm getting better at making more difficult levels. Count me in!

For RetroLemmini, not NL

I've attached an updated version of namida's .nxp (download link found on the previous page, 7) of the pack for v1.43 NL with the following changes:

- Corrected the Frenzy 9 - Fall Guy talisman to unlock the correct secret level. It was unlocking the wrong one.

- Moved the eraser piece on Pain 22 - Herculems down a pixel. The level was unsolvable otherwise with what seems to have been changed bomber mechanics. Interestingly enough, this level is fine in mobius' Flexible NeoLemmix Player version (in the OP) and hence doesn't need the eraser piece moved for that one.

Remember that you would need the 1.43n-F NL player to load this .nxp file. You can download this NL player here:

https://www.neolemmix.com/?page=download_list&program=16

Simply extract both the NL player and the .nxp file somewhere to your hard drive, double-click the NL player, and browse to the location where you extracted the .nxp file, and double click the .nxp file to load the pack.

The NL player v1.43n-F file is also attached here. I've also attached both the .nxp and the NL player v1.43n-F files in the OP for convenience and so that both versions of the pack and everything are in one place

https://www.lemmingsforums.net/index.php?topic=2203.msg52541#msg52541 

Ok, after conversing with Turrican on the Discord, he doesn't have the Lemmix version of the RotL pack anymore, but he tells me that all the levels in the beta Lemmix version were all the same ones as the Lemmini ones, including the ones in the Bonus rank. Most of these Bonus levels wouldn't work in Lemmix anyway due to plenty of Lemmini exclusive glitches not working on Lemmix and hence would need to be replaced with levels, perhaps with a Lemmix exclusive glitch, instead. He also says plenty of the levels in the beta Lemmix version had steel problems, and indeed that seems to be the case, reading through this topic and seeing some users posting about steel issues.

So, just the Lemmini version of the RotL pack should suffice for the time being. Perhaps the topic title and OP description can be changed for to reflect this?

On the other hand, most of the levels should be available on the Lemmings Level Database and hence if one wants the Dos/Lemmix experience of playing the levels there's that. One problem with this is that the levels there might not necessarily be the most up-to-date version in terms of backroute fixes that the corresponding Lemmini level received. However, I just remembered that the older NL editors have a mass convert feature that allows one to get .lvl files of the Lemmini levels

Even with that, it would still be a lot of work to do, whether or not one takes the levels from the LLD or via the mass convert feature, though the latter is of course far less work in terms of getting the actual .lvl files. Even moreso if backroute fixing in either approach and hence it would be way too much just to maintain an old version of the pack. So, if a Lemmix version of the RotL Lemmini pack is ever recreated, the way to go about this would just to leave the levels be, even if there are still backroutes. Most of the levels exist in the New Formats NL version of RotL or in the RotL Outtakes and hence backroute fixes should be applied to those instead. I certainly plan to take up updating the New Formats NL RotL v4.0 of the pack sometime in the future  

I've restored pack download for Lemmini All the download links are dead, so a few posts up in mobius' post I've went ahead and removed the mediafire links.

Also in regards to the Lemmix version of the pack, I unfortunately don't have it and hence that still needs to be restored if anyone still happens to have it

The pack for Lemmini is attached to this post The pack has the included music used for it, and interestingly enough the pack and the music together take up only 3.2MB, so fortunately no need to make the music a separate download from the pack itself It also means the pack can simply be downloaded as an attachment instead of needing to host the pack download on Dropbox or some other site!

I've also included attached the pack in the OP for convenience and also so that everything is in one place

Quote from: WillLem on March 20, 2026, 02:25:02 AMThe locked RRs for all these packs was happening due to a cleanse bug in the Editor. Thankfully, it's an easy fix to correct them all using RegEx in Notepad++

I've now triple-checked everything in all packs for:

"locked = True" when it should be "False" - all fixed
"locked = False" but "maxRR" is the same as "minRR", which also causes the RR to be locked - all fixed

Excellent work Perhaps it's best to post a tutorial on how to mass edit levels with Notepad++. I remember when I mentioned needing to open up every .ini level file to change the fall distance for a level pack I converted to SuperLemmini that you said there's a far faster and easier way to do so via Notepad++. I don't have it though. I'm not sure if one can do the same with ordinary Notepad.

QuoteAnd, of course, the cleanse bug is fixed in the Editor so this shouldn't happen again when converting/cleansing packs in the future!

Yup, as you have explained the packs predate the cleanse levels bug fix and hence explains why some levels had locked RR's when they shouldn't. It seems pretty random which levels had it, though.

Quote from: kaywhyn on March 20, 2026, 01:42:52 AMVersion 1.4 uploaded with the following level fix:

Heinous 27 - Narbacular Drop Unlocked the RR

Ah, checked this again and I'd set the property to False but the max RR was still 90, effectively keeping it locked.

I've done another check of Mobilems and there are a few other levels that slipped through the net due to this, I'll upload another fix now.

Indeed, we were both seeing the same thing with the RR being locked on the level, where in the editor I saw the "RR locked" box ticked (marked as true), whereas in contrast as you have explained, it was the opposite, set to false but as the max RR matched the min RR it essentially means the same thing as the RR being locked on the level.

Anyway, thanks for being prompt and fixing the other levels of the pack which had the locked RR issue!

Well, just as I recently became an uncle to my sister's son a few days ago, I just received news from my mom that a late cousin of mine who I saw a few weeks ago for a death anniversary commemoration for one of my mom's grandparents at my house (tradition in the Vietnamese culture to hold commemorations for the deceased in the family) passed. Earlier this month was the first time I've seen him in quite a while and boy was I aghast at his pale and gravelly ill appearance. We knew he was really sick, but we didn't know it would just be 3 more weeks until he passed. Well, he and I got to talk briefly a few weeks ago, but still, I'm sad to hear this news of losing my cousin

I messaged his daughter (my cousin once removed who's a few years younger than me) to send her my condolences, and those extend to her brother (also my younger cousin once removed) as well.

Quote from: Guigui on March 20, 2026, 08:58:41 PMCongrats on your sister and on you kaywhyn ! That is indeed a very nice moment for your family, enjoy it.

I remember being an uncle for the 1st time at the age of 12, my sister was older than me and she had kids very early. Found memories.

Thank you Guigui, I appreciate it! My mom and I came to visit my sister and my newborn nephew yesterday and he is just absolutely adorable

Just a heads up, that I'm not going anywhere, that I'm still going to be around despite my circumstances with a new addition to the family, but my sister gave birth to her first child as of about 7AM PST (Pacific Standard Time) this morning (March 20, 2026) to a beautiful boy. My parents came to visit her in the hospital this morning.

So, I'm officially an uncle to a nephew! In the same way my parents are finally first time grandparents after more than 70 years.

I'm going to go visit my sister and her newborn son tomorrow at her house when she is discharged from the hospital tomorrow. Pics to come later, either another post here or maybe on my "kaywhyn's blog" topic

Quote from: kaywhyn on March 17, 2026, 10:46:30 AMFor both the pack and the music, all you have to do is extract to your RetroLemmini directory. Everything will fall into place. Yea, I'm one of those people who likes to make extraction for people as simple as possible

That's great, but some people (myself included) prefer to handle extracting compressed files manually. Extracting directly to a folder can overwrite existing content in that folder, which isn't always desirable. Also, if for some reason the wrong target folder is selected or the .rar/.zip structure is incorrect (which can very easily happen by accident), the user can end up with a huge mess that they have to clear up manually (this only needed to happen to me once for me to never want to extract directly to a target folder ever again!)

Anyways, it's a good thing to provide the .rar/.zip in a directly-extractable format, and of course I realise you've carefully set up the .rar to extract correctly, so thanks again for doing that. Users can always handle it however they wish at their end.

Yea, it's all good. Personal preferences

QuoteUnlocked release rate for all levels except Black Hole 14 Hanglem, which is the only non-RR99 level in NepsterLems to feature locked release rate.

Yea, this level having its RR locked is fine since this conversion is based off the Old Formats NL version, and as ericderkovits mentioned Nepster locks the RR on the level and hence the SuperLemmini/RetroLemmini conversion of the level should as well. I agree that locking the RR is the right call here as eric has done In contrast, the SuperLemmini/RetroLemmini conversions that are based on the Lemmini version of the pack, like MobiLems v6, shouldn't have locked RR's for any of the levels since locking the RR isn't possible in Lemmini even though it is possible to have a locked RR in both SuperLemmini and RetroLemmini.

Version 1.4 uploaded with the following level fix:

Heinous 27 - Narbacular Drop Unlocked the RR

Perfect, thanks @kaywhyn.

The error happened due to a cleanse levels bug which has now been fixed, but the copy of the level included here had been processed before the fix.

Thanks for spotting and fixing it, much appreciated.

I appreciate it, but actually hrb264 spotted this and I took a look. I've modified my post to credit her there as well

Not sure what happened there when ericderkovits and WillLem ported the pack over to RetroLemmini, but perhaps either one of them know? Seems locking the RR was done by accident, as it's not locked in the SuperLemmini conversion.

I've also included my solving replay for the fixed Heinous 21 version in the pack download
