-
-Last year, I started reverse enginering _Neon Genesis Evangelion: Girlfriend of Steel_ with the intention of writing a replacement engine that runs on modern computers.
-I ended up losing interest, but not before cracking a few of the game data formats. I'm going to document them here, that way anyone who takes a similar
-interest in restoration or modding can have a head start.
-
-The source code of the abandoned project is available here: [fantatech-1776908508.tar.gz](/files/girlfriend-of-steel-re/fantatech-1776908508.tar.gz).
-It includes [ImHex](https://imhex.werwolv.net/) patterns and rudimentary decoders for some of the formats described below.
-
-## What game am I talking about?
-
-I actually looked at two different games. I will share the information I know about the 1997 formats, but the primary focus will be on the 2006 version.
-VNDB has a good record of all the available ports and translations here: [https://vndb.org/v556](https://vndb.org/v556).
-
-**_Neon Genesis Evangelion: Girlfriend of Steel (1997, PC)_**: This is the original release of the game. It's also the most widely available.
-I was able to buy a factory sealed copy on eBay. Surprisingly, you can still mount the ISO and run the ~30 year old binaries on Windows 11. It plays mostly
-fine with a [Shift-JIS locale emulator](https://github.com/xupefei/Locale-Emulator).
-The chunky bitmap graphics and audio, although charming, are considerably lower quality than in the 2006 version.
-
-**_Neon Genesis Evangelion: Girlfriend of Steel (Special Edition) (2006, PC)_**: Also called _Shin Seiki Evangelion: Koutetsu no Girlfriend Tokubetsu-hen_, is a remake.
-It has upgraded sounds and visuals, additional scenarios, and a full-motion video (Cinepak) intro sequence. It's also filled to the brim with DRM that makes it completely
-broken on any system that isn't running Windows XP with Direct3D acceleration.
-This will only run in VMWare because VirtualBox dropped 3D acceleration support for Windows XP guests.
-
-I have not been able to find a physical copy of the PC version of Special Edition for sale anywhere.
-The PSP version is available, but the image resolutions are smaller than those found in the PC version.
-
-Luckily, someone in 2020 found a copy and had the foresight to rip the disc and upload it to the The Internet Archive. This is the raw, original disc; DRM and all:
-[https://archive.org/details/ssekngpcredump](https://archive.org/details/ssekngpcredump) - [http://redump.org/disc/74520/](http://redump.org/disc/74520/).

-MD5: `536adbefc80a84378b65224fddf122e7` SHA-1: `77a03fb1823cb96189ac50b9afece8930e709c93`
-
-## Getting around DRM
-
-Special edition is secured with [SafeDisc](https://en.wikipedia.org/wiki/SafeDisc). It's completely broken on modern Windows, so you'll need to use a virtual machine to run the game.
-I had good success with Windows XP in VMWare with 3D acceleration enabled.
-
-Once the game is running in the VM (lots of fiddling, unfortunately) the executable can be dumped with [Scylla x86](https://x64dbg.com/).
-To save you the headache, here's the dump: [mana01_dump.tar.gz](/files/girlfriend-of-steel-re/mana01_dump.tar.gz)
-
-![001-scylla.png](/files/girlfriend-of-steel-re/001-scylla.png)
-
-Although it doesn't run, the dump is a correct PE file.
-Ghidra is able to create proper data and code cross-references. Here's a function that parses script keywords:

-
-## Custom file types (1997)
-
-* **LB5**: Lump file
-* **BP2**: Image (1997)
-* **BP3**: Image (2006)
-* **TXT**: Game script
-* **ZDF**: Animation data
-
-## Prior work
-
-When reverse engineering the 1997 game executable, I found several strings referencing something called "bmpwaku".
-This was the name given to the tiled bitmap rasterizer written by programmer Ritsurō Hashimoto.
-
-A small portion of the source code is still available on his website to this day: [bmpwaku.cpp](http://www.ritsuro.com/prog1/bmpwaku.html).
-This wasn't particularly useful, but it was cool to find.
-
-Aside from that, here are the existing tools I looked at:
-* [evac010](https://www.vector.co.jp/soft/win95/art/se055672.html): BP2 <-> BMP transcoder, likely written when the game came out in the 1990s.
-* [mdukat/EvaGOS\_engine](https://github.com/mdukat/EvaGOS_engine): Includes partial documentation of the game scripting language from the 1997 game.
-* [lb5\_decode.c](https://d3suu.neocities.org/EvaGOS_engine/lb5_decode.txt): LB5 unpacker, written by either mdukat or roxfan.
-* [Durik256/GOS2-Tools](https://github.com/Durik256/GOS2-Tools): Tools for dealing with files found in Girlfriend of Steel 2. Some overlap.
-
-## LB5
-
-These are very basic file archives. It's an `.IDX` file paired with either a `.BIN` or `.LB5`.
-
-There's no encryption, the idx file just stores the index into the bin/lb5. See ImHex patterns.
-
-## BP2 image format (1997)
-
-BP2 image format start with a custom header, followed by the standard bitmap file headers (`BITMAPFILEHEADER`, then `BITMAPINFOHEADER`).
-The custom header starts with a 32-bit uint32_t with value `999`. Search for that literal in the decompiler output to find the parser function.
-
-The 2nd field in the custom header defines the pixel format.
-| Value | Format                                   |
-| ----- | ---------------------------------------- |
-| `1`   | `INDEX8` - 8-bit index into palette data |
-| `2`   | `RGB24`                                  |
-| `3`   | `GRAY8`                                  |
-
-If the format is `INDEX8`, then the palette data is next.
-The length of the buffer is defined in the custom header.
-
-The rest of the file is image data encoded into chunks:
-```c
-struct BP2_Chunk
-{
-    u32 len;
-    u8  buf[len];
-};
-```
-
-Each chunk is a run-length encoded column of 8 pixels.
-To understand the specifics, it's easier to just look at the decompiler output or `ftformat.cc` in the source code linked above.
-
-## BP3 image format (Special Editioin)
-
-BP3 is similar. It supports more pixel formats and the image data is compressed into 8x8 blocks instead of 8-tall columns.
-
-| Value | Format              |
-| ----- | ------------------- |
-| `0`   | `SOLID` - One color |
-| `2`   | `BGR332`            |
-| `3`   | `BGR233`            |
-| `4`   | `GRAY4`             |
-| `5`   | `GRAY8`             |
-| `6`   | `BGR555`            |
-| `7`   | `BGR888`            |
-
-The decoder for BP3 is also in `ftformat.cc`.
-
-## TXT (1997)
-
-This is XOR-encrypted Shift_JIS text:
-
-```c
-for (u32 i = 0; i < txt_len; ++i) {
-    data[i] ^= 0xFF;
-}
-```
-
-## TXT (Special Edition)
-
-Same thing, but slightly different:
-
-```c
-for (u32 i = 0; i < len; ++i) {
-    if (data[i] > 0xF) {
-        data[i] = 0xE - data[i];
-    }
-}
-```
-
-## ZDF
-
-This file starts with a fourcc of `DFS0`.
