Lamune Translation (hacking and discussion)

zoom909 · October 20, 2013

It's old, it shouldn't be too bad, right?

Extract using ExtractData (engine type "Alcot")

Extracted scripts are binary, but you can see the lines of text in there. And each text is preceded by what looks like the line length.

Any hacker with some free time who wants to help me? (I might be able to do something by myself, but it'll probably involve a lot of trial and error and luck. A real hacker might be able to knock it out pretty fast.)

UPDATE:

As you could see from http://zoom909.blogspot.com, things are well underway but have hit a bit of a snag! Due to my quest to separate myself from hentai once and for all, I have chosen to work on the PS2 version of Lamune

SO, if you like Lamune and you like ero and can help, or end up talking to someone who can help:

I'm looking for a co-translator who is willing and able to translate a relatively small amount of explicit lines. You can also be in charge of building the PC version patch if that appeals to you.
Offer expires after 90 days.

Ohh yes let's get Lamune Tled i will help anyway i can for this

zoom909 · October 22, 2013

OK, great, I'll keep that in mind. If this turns into a real project.

But for right now, it's the technical side that needs work as a prerequisite.

Meanwhile, I will keep plugging along with my meagre skills in the hopes that something works out.

The compression is a well-known type, so thankfully there's a library for that.

-I need to try and encrypt it properly or the game will reject it.

-Then, looks like there is also the problem of getting the lines of text out of the script object file so I can edit them, and back in again.

And today, I discovered that another game I have (http://vndb.org/v702) has scripts which are source, not binary objects. So they can be loaded and worked with like ordinary text files. That's more like what I was used to with the Miku VNs.

-Still would need to repack them properly before it can work.

I can try extracting into readable files so you can start translating, but for final insertion you would probably need custom tool.

But the torrent I have is just not downloading so maybe you want to hop on TS and send me just the needed files and I will see.

If you have westside free packages and the archive for this Lamune game is also in arc, try using nekof3cv, I can email it to you if you want. It seems to work with other nekoneko games but again the torrent for this is not downloading so I can't see.

I remember liking the anime a long time ago and I was always curious to see the VN being translated one day,and now someone is doing it!

zoom909 · November 8, 2013

Yeah, and that someone is me.

I was kind of keeping a low profile until it gets going a little more.

Already twice in the last decade someone tried to translate it, but it didn't work out.

3rd time's the charm? Hopefully...

some_loli_catgirl · November 11, 2013

I've finished the script tool for this project. It's available on Gemot Encubed, Zoom909 already has the tool.

some_loli_catgirl · November 21, 2013

So novelnews.net seems to be down, have you downloaded the newest version before it went down? This is the one where I added labels and choice/goto support.

zoom909 · November 21, 2013

Yeah I managed to get it before that happened.

Play-tested very briefly on the first script with a choice--seems fine now. Thanks again.

By the way, you don't happen to know about PS2 hacking, do you? There is a new version of Lamune that has 6 heroines instead of 4.

Just thinking ahead (way, way ahead)

メルP · November 22, 2013

There is a new version of Lamune that has 6 heroines instead of 4.

What about 3 releases of this VN after the PS2 version? They do not include the new stuff?

I mean, do they really sell it again and again without adding anything new... I don't want to believe.

zoom909 · November 22, 2013

You looked at vndb, didn't you...this is their shortcoming...they don't distinguish between just repackaging the game like for download or including it in a collector's box, and actual enhanced versions of the game.

According to EGS there are really only 2 versions of Lamune:

the old 18+ one for PC (called just "Lamune")

the new one for PS2 (called "Lamune: The Glass Bottle that Reflects the Sea")

Some games get enhanced in a console version.

Some get enhanced in a new PC version.

Some go through many cycles of enhancement between console and PC.

Some never get enhanced at all.

I don't know who decides all that stuff--I just know it isn't me.

Well, I saw the EGS too. But it's not like their data is 100% accurate too. Well the main reason I asked is just I really fail to understand why wouldn't they include the new content in the releases following the PS2. It is probably not worth to make the new content for some old VN, but if it's already there, in PS2, putting it in PC version should be trivial.

Well, anyway. Have you checked that PS2 version? It is possible that the console version uses the same script format as the PC. It can even use the same archive format in some cases. That would mean that there isn't much to hack.

zoom909 · December 4, 2013

Well, you're quite an optimist, aren't you? But it could just as easily be an entirely different format.

Anyway, the archive format is definitely not the same. It's one gigantic archive volume helpfully named "data.bin" <_<

Until I can open it, I won't know if the script format matches or not.

The program code contains the following string:

H3D> HuneX Consumer 3D System for PlayStation2.........H3D> Runtime Library Release %s......VER 1.01........H3D> ------------------------------------------.........H3D> WELCOME TO PLEASANT GAME DEVELOPMENT!.....

That's the only identifying mark I found. Here's their website, they have programmed a LOT of games:

http://www.hunex.co.jp/p_02/k_ps2.html

I also want to check and make sure that PCSX2 can actually run Lamune.

The Lamune PC game is the original and a classic, so I won't lose too much sleep over it either way. However, the collector in me would like to pursue the PS2 version.

Nanashi3 · December 4, 2013

Can you post a screenshot of the first few bytes from that file in a hexadecimal editor?

zoom909 · December 4, 2013

OK here.

REtransInternational · December 4, 2013

"MF" and not "MZ"? Just need a "This program cannot be run in PS1 mode" string and everything feels so familiar... :lol:

The header seems relatively trivial, DVD offset being aligned on 2048 (0x800) boundaries.

struct TOCENTRY {

u32le offset;
u32le compressed?;
u32le usize?;  // if compressed? is 0, same as .size
}

Pretty amazing that you could deduce all this, where all I saw was a seemingly random smattering of Bytes!

So, it looks like the interesting files are 11, 12, 13, 14, right? Could you tell for sure that 12 was scripts, even though it's compressed? Did you see some bits of text peeking through?

Searching for "UFFA"...found the following:

"HEADER

2 byte header (always MF)

2 bytes null

4 bytes starting offset

4 bytes null

TABLE

4 bytes filesize

4 bytes offset

1 bytes flag

3 bytes null

4 bytes uncompressed filesize

Flag: Either 0x00 or 0x01. This tells if it's a compressed file or not (UFFA).

The compression used is CLZ, which is a variant of LZ

IMPORTANT NOTE ABOUT OFFSETS: They will ALWAYS be rounded to either 0x800 or 0x1000. 0xFF is used for padding.

Uncompressed filesize: If the file is not UFFA, just copy filesize. If the file is UFFA then copy 4 bytes starting at 0x08 in the UFFA file."

(Keep in mind that I have no experience with data compression)

Iirc mirror moon did work on ps2 fate stay night realta nua to import voice files in their patch installer for pc fsn. Maybe they have tools that handle the format.

zoom909 · December 5, 2013

OK, thanks. I will see if I can find out anything from Mirror Moon folks

メルP · December 5, 2013

Somewhere I had a tool that was capable of extracting PS2 FSN stuff... written in python. but I don't remember what exactly it were extracting. I think it was capable of extracting graphics and scripts... I'll see if I can find it.

メルP · December 5, 2013

Well I found it, but I don't really remember who made it. It was sooo long ago that I was messing with FSN PS2. So not sure if he wants me to post it. Though I can send it to you in PM...

Edit: but AFAIR it takes mounted iso as input and searches for the files there... so perhaps it needs to be modified to work with something else.

Nanashi3 · December 5, 2013

Thanks for the file @MeruP, though it's a pity it is in py2exe form.

At the moment, I'm trying to grab a working PCSX2 emulator for debugging.

The decompression routine seems to be a fairly run-of-the-mill LZSS implementation (@.text:001062F8 in SLPM_660.83), 12+4 with big endian caveat (I posted a decompression script for Strapani earlier)

however any output I got so far is garbage.

Here's the archive if someone wants to have a look:

Edit2: My bad!! I forgot to skip a value!

Here is the script MF archive:

Edit3: fixed bad dump http://www36.zippyshare.com/v/26734086/file.html

Not the type to call unnecessary attention to myself, but this is kind of a big change in the project's direction...
