I split some stuff out of a Sega Ages 2500 data package (the bin.pak files) and they're all compressed with a form identified as "lzs2" in the file. Is there a way to decompress this? Google isn't helping. Thanks.

That is part of the LHA compression format popular in japan and was used by iD in Doom and Quake. Try 7zip utility to open it.

Is there a command-line tool? I'm on Linux right now so I don't have the 7z utility and both the 7za tool and unlzma refuses to see it.

Yeah try using lha. If you don't have it im sure the repo of your distro has it. Its an old format after all.

Damn, I was checking wikipedia and it says

Quote

LArc uses the same file format as .LZH, but was written by Kazuhiko Miki, Haruhiko Okumura, Ken Masuyama, with extension name '.LZS'.[http://www.lzh-zip.c...ion/ext31.html]

The link is in japanese, something tells me that this is an encrypted compression but don't take my word on this.

[Andlabs]

I don't understand that page, and it looks like the lha program expects something different?

Also some of these files extract to tm2 files but the Linux tools for them are gone (or their source code was pulled)?

If you're on a Debian-based distro, you may want to install p7zip-full to open 7Z-compressed files (and variants) via file-roller.

[Andlabs]

I had that, but installing the other packages in the p7zip range turned up nothing in file-roller. I'm guessing this is a stream compressor like gzip and not a compressed archive format...

Sample file (from Tetris Collection but I think all the other SA2500 games use lzs2 too, and there's gems in them too! I think this one is just an arcade flier for Bloxeed)

How do I view TIM2 files in Linux? I'm not getting any hits and TimTool in wine complained about not being able to open the destination directory. Treeki got the format cracked after we spent some time looking at the disassembled ELF and I just want to make sure everything is right. Thanks.

[Andlabs]

Okay, how about this:

TIM2 file - http://idisk.mac.com...etris_md_11.tm2
Expected - http://segaretro.org...s_MD_JP_Box.jpg
What I got - http://I.imgur.com/gtyOB.png
What Treeki got - http://dl.dropbox.co.../tetrismd11.png

We both ran Game Graphic Studio (I ran it in wine).

I ran TimTool again and it appeared to do nothing other than create result.log; it didn't even tell me how to use it and what it wanted to do and I can't understand this source :| xnView also showed me an invalid palette.

Does anyone at all know what's up? Thanks.

[Black Squirrel]

I feel clever

Though all I did was open this up in Game Graphic Studio (6.1.1 - the first one that came up) and change the interlace method to BGR+I

[Andlabs]

Well that explains it: I have to reload the file from the list at the bottom after clicking those radio buttons. Thanks. Now if only there was a batch processor...

When I get more disk space I can download and tear through the rest of the series. I'll post the source to the lzs2 compression when Treeki gets back to me. (I could also post the program to rip apart the BIN.PAK file in Tetris Collection but apparently the format is different for some of the earlier/later games...)

Maybe I should put this into its own thread but

the Fantasy Zone Complete Collection is a goldmine

Manuals and arcade flyers for every Fantasy Zone game's JP, US, and EU releases (as far as Sega consoles go, at least)
The entire set of planning pages for Fantasy Zone II
Assorted concept art and cover art masters

come and get it? (90MB, all BMP files)

Holy shit, this is some cool stuff. Thanks for taking your time to rip these!


By the way, is there a way to rip the Fantasy Zone II Arcade ROMs from that disc? I know there's a pirate arcade with that game on it, so it must be really using actual ROMs and an emulator.
