GeoBob Engine

The GeoBob Engine is an engine created by "Balls" in 1996 for physics on the PlayStation, Sega Saturn, and as the GeoBob Engine 2 in 1999, the Dreamcast, PlayStation 2, Xbox, and Nintendo GameCube. (Both engines were optimized for Windows 95-XP, in addition.) All of the 1996-1999 Geo Adventure and 1999-2005 Greeny Phatom: The Revenge of Gree Guy games use the. The engine was made for major "Balls" games such as Geo Adventure 2, platformers, and 3D Greeny Phatom games.

The engine is named after Geo Guy from Geo Universal and Green Bob from Greeny Phatom.

Development
In 1990, Sam Garcia, Gabriel Garcia and Michael Wildshill had an idea that they would develop a engine for upcoming games developed in-house or external developers owned by "Balls". They gathered a team of programmers and they started the development in 1991 under the codenames "Sinatra", "London" and "Dragon". After the first prototype of GeoBob Engine demo was shown to John Harris in 1993, John approved and joined the development team.

The first version of the engine was called "Balls" Engine and it's SDK was announced to be released in 1994.

"Balls" Engine
Available for licensees: February 5th, 1994

The engine family started from "Balls" Engine, developed by a team of programmers called "The "Balls" Engine Development Team", and the engine was supposed to be a physics engine, but the development team's talent "got further" and decided to make the "Balls" Engine one of the most succesful and first 3D engines in 1990s. It also was described to "integrated rendering, collision detection, AI, visibility, networking, scripting, file system management, and much more, into one complete engine". Despite all of the above, no games were made with this system.

GeoBob Engine 1
After New Year's Eve 1995, the name was changed to GeoBob Engine, because the development team was said to develop the engine to a new Geo Universal game, which was later to come Geo Adventure. The name comes from Green Bob from Greeny Phatom and Geo Guy from Geo Universal. The engine was supported on the PlayStation, Sega Saturn, and Windows 95-98.

GeoBob Engine 2
The GeoBob Engine 2 is the first version of GeoBob Engine to come with GeoCore proccessor (which was developed by ATI, AMD, 3dFX and a large team of programmers and technicians at "Balls") and a SD card with 10GB. The GeoBob Engine 2 was the biggest update to date in GeoBob Engine history.

GeoBob Engine 4
The new game engine was announced at E3 2013 with GC3 (GeoCore 3), a new processor developed by AMD, Intel, NVidia, Sony, Nintendo, Microsoft, Google and "Balls".
