Lemmings Revolution giving incomplete screen captures is a http://www.lemmingsforums.com/index.php?topic=615.msg13747#msg13747" class="bbc_link" target="_blank">known issue which has been brought up before. I doubt there's much of a remedy for it, so you won't be able to use screen capture software to get the job done.

Instead, I recommend recording your video card's output signal. Most off-the-shelf video cards have auxiliary output, be it S-Video or Component, in addition to the standard VGA or DVI port. On the other hand, most video cards placed into pre-assembled computers like HP or Dell almost always do NOT have additional outputs.

I generally build my own computers, but I'm currently on a Dell because it's better than what I had and through roundabout means I got it for free. It may be evil, but it was free evil. What I do is use a device that accepts the VGA output of my video card, duplicates the signal so I can still use the monitor with it, and also converts the signal and outputs it as both Composite (not to be confused with Component) and S-Video. Neither of those formats is especially useful for game recording, unless you're talking old games with low resolutions... like Lemmings Revolution.

You should message him and ask. (-:

I'd like to gather up some channel links in this post, so we can find your stuff!

All my Lemmings videos are currently located here:

Technical advice is welcome too. What hardware and software do you need, how do you set it up, how do you make your videos look nice (if at all)?

I've historically used DosBox for capture, then Avisynth for editing. The result is generally upsampled to some HD size (mainly to retain audio quality on YouTube) and encoded to MP4. I also capture videos from console systems using a typical capture device, often with some fancy deinterlacing (QTGMC is slow, but gee whiz is it good). I oughtta get an HD capture device and say goodbye to deinterlacing forever...

Another correct answer! In case you're wondering why I'm using math questions, it's because there are many real-world situations that you'll need to know how to solve. Often times, this means math. It doesn't matter how clever you may be; sometimes the only way to know something is to calculate it.

Here's one I came up with last night, and this one I don't already know the answer to, so surprise me!

I'm currently working on http://bulbapedia.bulbagarden.net/wiki/Save_data_structure_in_Generation_III" class="bbc_link" target="_blank">hacking the GBA Pokémon games and a brief statistical curiosity comes to mind. Within the data structure for individual Pokémon is an encrypted 48-byte section comprised of four 12-byte chunks. The order of the chunks is determined by examining another value in the data structure, which is entirely random.

Let's call the four data chunks A, B, C and D. They can appear in any order, such as ABCD, ABDC, ACBD, ACDB, ADBC, etc. There are 24 such combinations. The order is determined by taking that randomly-generated field from elsewhere in the data structure, and taking the remainder of its division by 24. Or "modulus 24", despite that actually being the wrong word for the operation. (-: Since the value that determines the chunk order is entirely random and generated when a Pokémon is encountered in the wild, there's effectively a 1/24 chance of a Pokémon having any particular chunk order. (This isn't entirely true, because the randomized value is 32 bits and 4294967296 doesn't divide evenly by 24, but let's just pretend that it does)

As part of my practical testing, I'm going to go into the game and keep catching Pokémon until I have at least one with every one of those 24 chunk orderings. The problem in its simplest form is that I have a 1-in-X chance of getting something, and I want to get X of them. Pretending I could start out with 0 Pokémon and begin catching from there, about how many would I have to encounter to get all 24 orders? Let's use a 99% likelihood as the target.

Okay, Mr. Mathy Pants. (-:

Let's say that I wanted to have a less than 1% chance of leaving that dungeon empty-handed. How many Starman Supers would that take?

Along those statistics lines...

The game Earthbound (aka Mother 2) has a few rare items that have a 1/128 chance to drop after defeating particular enemies. Heck, it has some common items that are also that likely to drop from certain enemies. But the most notorious of these items is the Sword of Kings, the only weapon Poo can equip that won't lower his stats.

The Sword of Kings can be found only by defeating an enemy called Starman Super, and at a 1/128 rate at that. Starman Super only appears in one dungeon in the game, and they're gone forever after you complete that dungeon. So, unsurprisingly, people spend a lot of time in that dungeon to get that sword.

Last time I played the game, I counted how many Starman Supers I defeated. I went through exactly 256 of them and did NOT get my Sword of Kings. What is the likelihood, as a percentage, of that happening?

Awesome. Your solution for Space 2 is ingenious. You win a cookie!

I've gone back and edited my posts to contain links to yours as well as your solutions on YouTube. Here are the videos:

Nicely done! I've edited the video and put it up on YouTube:

I think at 1:04 you technically used the Jumper on the wrong Lemming. The one that did the platforming would have been farther to the right than where the cursor was. Either way, that's just a technicality, and it doesn't make your solution any less valid.

Also, there was an unusually long pause at 1:36. I took the liberty of shortening that. (-:

I'm going to get some of these printed up as standees, I think, hehe...

*Imagines a desk littered with assassinated Lemmings*

On an unrelated note, Rasputin was always the name of my Bulbasaur. I am not joking.

Thanks, though I'm a step ahead of you. I forgot I had the disc image on my hard drive still because I missed it when backing everything up to DVD archives. (-:

Your earlier work was a good start. I've figured out the remainder of the file. The format is as follows:


File
===============================================================================
Manifest    Entry[568]    Cell manifest (0x08E0 bytes)
CellData    Byte[]        Cell data
===============================================================================

Entry
===============================================================================
Animation    Byte      The animation this cell belongs to
Flags        Byte      For 128px cells, 0x80 means "last cell in animation"
Offset       UInt16    The location in CellData of the Cell structure
===============================================================================

  Offset is stored as a 16-bit value to save space. To resolve the actual
  address, first add 0x08E0 (for the manifest), then add Animation * 0x4000 to
  resolve the actual offset of the cell in the file.

Cell
===============================================================================
LineOffsets    UInt16[]    Offsets relative to the Cell structure per Scanline
LineData       Byte[]      Scanline data
===============================================================================

  The LineOffsets are relative to the beginning of the Cell structure, not the
  beginning of LineData.

  The number of elements in LineOffsets depends on the file being processed.
  For LEMM.MHC, it's 64, and for LEMM128.MHC, it's 128.

Scanline
===============================================================================
Lead      Byte      Number of transparent pixels on the left side of the line
Trail     Byte      Number of transparent pixels on the right side of the line
Pixels    Byte[]    Width - Lead - Trail bytes of pixel data for the line
===============================================================================

  Pixel values represent palette indexes.
Attached to this post are ZIP files containing every sprite from both the 64 and 128 pixel files. For the rest of you, some sample rips:

This is awesome! I love the technical expertise we have in this community.

If you feel up to doing all the post-production editing, I guess I can just start doing and posting "one-take" videos (perhaps on top of doing screenshots as well) for all my future attempts, and people can do as they please with the videos.

Absolutely. I can set up my connection here so you can upload directly to my computer. Since the DosBox capture is lossless, you can use the resulting clips for pixel-perfect screenshots as well. I can show you how to do that.

You may want to record with sound effects on, but music off. I personally have been exiting and re-entering the level each take so the music would restart at the beginning of the video, but if that's too tedious for your liking you can just disable music and I can put it back in after the fact.
