This repository is filled with various notes on various different formats that I've reversed overtime. A lot of these are provided in Rehex's Binary Template format, which is easily translatable into C/C++ and most other languages.

UK-based developer that shut down in 2013. Developed a number of different games, some of which do seem to share common technology.
This is the term we'll use to refer to Blitz's technology used in earlier games from the PlayStation, Nintendo 64 and Saturn era, starting with Glover.

- Package format uses the extension '.WAD'.
- It uses a fairly simple scripting language, which seemed to fall out of use after the first game.

Unfortunately only used for one game, which, you guessed it, was Martian Gothic: Unification.
- Excluding the
QMDX.dll, which isn't theirs, the oldest file in the PC version is from August 1998. - According to MobyGames, this was the last title Creative Reality would produce.
- They appear to have made a mistake with the application icon; the largest size has the smaller icon overlaid on top.
- PlayStation port was handled by Coyote Developments Ltd., which went into administration in 2006.
- Some of the textures are appended with 'tiff' which may suggest they used it as an intermediate format before conversion.

Unaware of any proper name for this particular engine.
The engine was developed from scratch with a next-gen mindset that went away from the grid-based logic of Tomb Raider games. On the graphics side, the PC version included features like normal mapping, environment mapping, variable-rate animations and real-time morphing, which all used Direct3D 8.0a's fixed-function pipeline. On the sound side, the most important feature was real-time environment-aware sound effects using DirectSound 8 and EAX 1.0.
- The game uses the GameSpy SDK for multi-player.
- The game was statically linked with
engine_pc.libon PC andengine_ps2.libon PS2. - PlayStation 2 version of the game was botched. It doesn't even use the integrated hardware vector units.
- Some of the internal texture metadata uses the 'tga' extension which may suggest they used it as an intermediate format before conversion.
- An official level editor was planned, but never released due to poor sales.
Unaware of any proper name for this particular engine. There is some cross-over between this and the engine developed for the cancelled Tomb Raider Anniversary.

Polish company primarily known for producing Kao the Kangaroo. Seems that the engine they developed ended up getting used for a number of different games and ported to a number of different platforms.
Listing this separately for now as it seems quite different to the tech used in their later titles.
Name was picked based on the code path indicated by strings in Penguin Kelvin, specifically, C:\coders\denis\denis\.
Only confirmed titles are here. Confirmation is performed by finding matching/similar formats, and matching/similar class names and strings in the executable.

As usual, I've decided to use this name to identify the technology but otherwise can't find any official name or term used for the engine. There is a config file in a few titles named 'elephant', which happens to align with their logo and who knows, might have served as an internal name for the engine.

- I Love Horses: Rider's Paradise, which is attributed as a Destineer title, appears to use this engine. It may have originally been intended as a sequel to My Horse & Me 2.
