# Yamagi Quake II Remaster

This is an experimental fork of Yamagi Quake II with ongoing work to add
support for Quake II Enhanced aka Q2 Remaster(ed). This enhanced version
has a lot non trivial changes, adding support isn't easy and takes time.
Feel free to try this code but you mileage may vary.

Have a look at the yquake2 repository for the "normal" Yamagi Quake II:
https://github.com/yquake2/yquake2

Alpha windows 64 bit [binaries](https://github.com/yquake2/yquake2remaster/releases).

 * GL1/GL3/GLES3/VK:
   * base1: no known issies
   * base2: no known issies
   * q64/outpost: no known issies
   * mguhub: loaded, sometimes broken logic for surface fall in next maps
 * GL4:
   * base1: unchecked
   * base2: unchecked
   * q64/outpost: unchecked
   * mguhub: unchecked
 * SOFT:
   * base1: broken wall light
   * base2: broken wall light
   * q64/outpost: no known issies
   * mguhub: broken wall light, sometimes broken logic for surface fall in next maps

Monsters:
  * incorrect dead animation for Arachnid,
  * broken fire effect for Guardian.

| md3    | Quake 3         | 16 bit       | Many   | No tags support                         |
| md5    | Doom 3/Quake 4  | float        | Many   | Requires md2 for skins                  |

All models support only single texture for all meshes and only up to 255 frames.

Texture support:

| Format | Original Game  | Comments |
| ------ | -------------- | -------- |
| wal    | Quake 2        | 8 bit    |
| wal    | Daikatana      | 8 bit    |
| m8     | Heretic 2      | 8 bit    |
| m32    | Heretic 2      | 24 bit   |
| pcx    | Quake2         | 24 bit   |
| tga    | Quake2         | 24 bit   |
| png    | retexturing    | 24 bit   |
| jpg    | retexturing    | 24 bit   |
| bmp    | Daikatana      | 24 bit   |

Maps support:

| Format | Version | Game                                       |
| ------ | ------- | ------------------------------------------ |
| IBSP   | 39      | Quake 2 / Anachronox / Kingpin / Heretic 2 |

Note:
 * SiN Gold has IBSP/41 format but has different size of lump and is
   unsupported.
 * Non Quake 2 maps are limmited mostly view only, and could have issues
   with tranparency or some animations flags and properties.

Goals (finished):
  * BSPX DECOUPLEDLM light map support (base1),
  * QBSP map format support (mguhub),
  * Use ffmpeg for load any video,
  * RoQ and Theora cinematic videos support.
  * Cinematic videos support in smk, mpeg, ogv format,
  * Daikatana/Heretic 2 map partial format support,
  * md5 improve load speed,
  * support Anachronox .dat format,
  * add debug progress loading code for maps.

Goals (none of it finished):
  * Single player support,
  * Support effects and additional flags for ReRelease when possible.

Bonus goals:
  * Port SiN/Daikatana pack support from pakextract,
  * support surface flags and content types for Daikatana, Heretic 2, Anachronox,
  * Use shared model cache in client code insted reimplemnet in each render,
  * Check load soft colormap as 24bit color,
  * Use separete texture hi-color buffer for ui in soft render,
  * Convert map surface flag by game type,
  * Cleanup function declarations in game save code,
  * Use 3 bytes vertex normal,
  * Support scalled textures for models and walls in soft render and fix
    lighting with remastered maps,
  * modified ReRelease game code support with removed KEX only related code.

Not a goal:
  * multiplayer protocol support with KEX engine,
  * support KEX engine features (inventary, compass and so on),
  * [KEX game library support](https://github.com/id-Software/quake2-rerelease-dll).

# Yamagi Quake II


Yamagi Quake II is an enhanced client for id Software's Quake
II with focus on offline and coop gameplay. Both the gameplay and the graphics
are unchanged, but many bugs in the last official release were fixed and some
nice to have features like widescreen support and a modern OpenGL 3.2 renderer
were added. Unlike most other Quake II source ports Yamagi Quake II is fully 64-bit
clean. It works perfectly on modern processors and operating systems. Yamagi
Quake II runs on nearly all common platforms; including FreeBSD, Linux, NetBSD,
OpenBSD, Windows and macOS (experimental).

This code is built upon Icculus Quake II, which itself is based on Quake II
3.21. Yamagi Quake II is released under the terms of the GPL version 2. See the
LICENSE file for further information.
