Lemmings PSP

[Simon]

State of the art for DOS L2 is that two lems are lost in the entire game, one is the blocker in Magnificent Severn, and one in Snowed In (Polar tribe).

So Close But So Far Away (gold is lose-4) uses vertical crawling for lose-0, whereas crawling doesn't exist in L1 and very likely not in the PSP version either. Tension Sheet, which you've already seen, uses the overlap of miner and basher, which is already hard to time in DOS L2, and I don't know the exact PSP physics either to tell whether it's possible there.

Secret of Nimh has a lose-0 method in DOS which I don't recall exactly, but cc was among those who discovered it. The fundamental idea is to eschew the blocker, and instead send lots of climbers over the wall to dig it away AT-style, generating a walkable slope when running out of climbers. DOS L2 has horrible selection priority, so execution was a hassle in DOS.

Keep in mind that all of the better-than-gold solutions in DOS L2 are probably oversights of the developers, and the intended routes do not allow anything better than the gold requirement.

I was testing DOS and the PSP to see which one can build farther and it looks like the PSP is a little farther. I even made sure to prove that I used three builders, by setting the number to 99. The Lemming startled building as soon as he was turned around. I just now realized it would have been better to test it, by turning him into a builder upon landing. That's gonna require a video for the PSP for proof. I can't tell for sure that the square terrain in both version are exactly the same size. The PSP picture is zoomed in, but there are videos of the Crystal levels with that terrain. The reason I test this is because I was still wondering why in my "Fix the road quick" remake, even though the distance of the brown stairs in the remake looks the same as the original, it still only takes three builders in the remake to reach the long diangle stair. There's a video if you want to see what I mean.

But that's just a custom level. I'm gonna try to test this on the real levels, or build another good small level that is perfect for this.

Edit: I tested it on Fun 25, because the nets on both DOS and PSP looks the same sizes and I noticed something about the builder. When you first turn the Lemming into a builder, both Lemmings in DOS and PSP will land on the same spot when only one stair was used, but if you make him build again after he's done, for some reason the PSP stair grows longer than DOS.

I'd like to get the PSP version. Can you recommend a good emulator? or where to find one? Or better; a good place to get the 'ROM's of the game that aren't in 15 separate RAR files that you have to combine somehow " title="Angry" class="smiley" /> ...

I don't think there's any point in getting the PSP version when you already have Lemmix, unless you really want a handheld Lemmings game and play the new 36 levels, that I can already rebuild into Lemmix.

I was testing DOS and the PSP to see which one can build farther and it looks like the PSP is a little farther.

Very interesting.  From the screenshots, it looks like the bricks are offset slightly more on the PSP version compared to DOS.  On DOS, each step is exactly 2 pixels ahead of the previous one, and the width of one step is 6 pixels, so for example the 4th step will be horizontally ahead of the 1st step by exactly the full length of a step.

On PSP it looks more like the 3rd step will already be horizontally ahead of the 1st step by full length of a step (or almost that, it kinda looks like it falls short by a small amount).  Nevertheless the overall slope of the staircase looks very close to that of the DOS version, so I guess maybe each step in PSP is slightly thicker vertically than DOS version?

Anyway, regardless of details, it does look like the exact setup of builder staircase is very slightly different on PSP compared to DOS, which may account for the difference you observed.  It is also possible that maybe the dimensions of the other terrain (eg. the blocks) differ slightly as well, but there's no good way to determine that from the screenshots.

At least the difference is such that builders can reach a little farther on PSP, so I guess it gives a little more margin of error for building.  Maybe that's why they end up not matching the DOS builder setup exactly.

Here's one done on Fun 25. The nets in both version really look the same sizes, so nets are the best for testing this. The difference of the stair length is more noticeable when two or more builders are used. I'm gonna go back to making those special levels from the PSP in Lemmix. I still want to finish it and see them in DOS graphics.

I found another level that has breakable steels. It's in one of the 36 special levels, called "Release is the word". The steel that is below the exit, can be destroyed too. I made it indestructible in Lemmix.

I noticed something in this picture of the beta version of the "Wrong points of view" level. You can see the electric trap, that was only used once, in the original Lemmings, from Mayhem 23 is there. That trap was removed, in the final version. If you were to take the bottom path, to beat the level, you're gonna need to use a bomber, to avoid the trap and not build over it. There's eight builders and you need all of them, for the part near the exit.
