Download archives of all PR2 levels
#1
Star 
Hey!

as maybe someone remembers I downloaded all PR2 levels some months ago. Suuper asked me to upload them so now I can offer you all levels as compressed archives (SquashFS images). There are 7 images of 2-3GB size. All images decompressed will result in 80GB of data but you can use them without unpacking by mounting them on Linux. On Windows you need to use unsquashfs binaries to unpack them.

You can download everything from MEGA.nz: https://mega.nz/#F!xZoGVaqR!aKpm8zDtgOE7nN6pWv1Bzw

Having people PM you for the links is extremely inconvenient. You could probably use a file sharing service (mega.co.nz comes to mind) if you want to avoid posting links to your server.
If you need to contact me for any reason, or if you have any questions, concerns, problems or requests, message me here or email me at aaaaaa123456789@acidch.at.

I can configure my server for public use but I thought that there are very few people who have use for the archives. I used my server because I can't max out otherwise my upload link (300Mbit/s).

EDIT: I followed Ax6 advice and uploaded everything to mega.co.nz (more archives will be available soon)

I don't know how to use this lol but I'm glad they're never lost!

Also, if all PR2 levels are only 80GB then Jiggmin was really really greedy not to increase art limit :L

Not to mention that if he compressed the levels they'd be way smaller; and if he stored them in an efficient format, they'd be even smaller.

The format I developed for that community racing project, which was blocks-only so far, was smaller than Jiggmin's format by up to an order of magnitude.
The waste of space Jiggmin managed to achieve was sad.

the fact that they were fucking uncompressed .txts....

like he could have at least compressed them with fucking gzip or something

also if I have time I'll get the files and then put them in an lzma2 tarball

squashfs supports lzma2 too. I recompressed levels 0 to 1M with it, and that got it down to 83% of the size of the squashfs FastiQ made.

I think squashfs is more useful here than a tarball.

Probably because it's kind of part of those people's childhood.

Considering there's roughly 6 million levels, and only a very tiny portion of those have any real content to speak of (most levels don't have more than a few blocks and nearly no art), it's actually too much.

Wouldn't tarring them and then compressing with lzma2 do pretty much the exact same thing that squashfs would do? I'm a bit unfamiliar with squashfs but from the quick check I did with the first 5k levels it seems like the tarball will be somewhat smaller overall, which probably matters more when the whole thing is well over a gigabyte.

squashfs is useful here because you can look at the files without unpacking the full tarball. You could serve these files from a 20 GB VPS because you can just mount the images without unpacking them.

The reason a tarball compresses slightly better is that the compression doesn't care about the file format. It treats the tarball as a single stream of bytes, and that means that decoding one particular file also requires decoding other parts of the stream (potentially all of the stream up to that point, depending on the algorithm and how intelligent the implementation is). squashfs is still useful when you're using the files, and that's worth the small amount of extra space.

ah that makes sense. I was thinking of just smaller downloads + running locally but that it a better solution overall.

Fair enough
Yeah I've seen just blank levels, levels with a block + finish, levels that just write "cowboy" and have no blocks... but yeah I guess that's a lot when you think about 6mil levels and these ones being quite a lot of them
