Gridlee (c) 1983 Videa.

An early shoot 'em up game in which you exist on a plane that disappears into the horizon. You move on a small grid, catching balls, avoiding the grid squares that have been touched by the bad guys, and shooting the bad guys when they are in the air.

Originally named 'Pogoz', this prototype was never released. The game was put out on field test and did poorly, so Gottlieb decided not to build it. Only one unit was built.

Videa was started in November of 1981 as a video game development company. Around that time were 'Gridle' was submitted and refused by Gottlieb, the assets of Videa (but not the corporate entity) were acquired by Pizza Time Theater. The new corporation, formed from the combination of the existing Pizza Time engineering department and the employees of and assets of Videa, was named 'Sente Technology'.

The former principles of Videa, Ed Rotberg, Roger Hector, and Howard Delmann, gave the developers of MAME permission to add the game and freely distribute it. The game code remains copyrighted and owned by the three men.

- Gridlee is a game that was never released. It was developed by Videa, Inc. in 1982, on hardware designed by Howard Delman. Videa was eventually acquired by Pizza Time Theater and formed the core of their new Sente Technologies division. The hardware that Gridlee ran on evolved into the Bally/Sente SAC I system, which provided a cartridge-based arcade gaming platform. Thanks to the kind generosity of the three co-founders of Videa -- Howard Delman, Ed Rotberg, and Roger Hector -- the original PROM images from the only existing Gridlee machine have been made available for free, non-commerical use. The ROMs were dumped from the only known existing prototype, owned by Dale Luck.

- 0.116u2: Zsolt Vasvari fixed regressions in Gridlee.

- 0.113u2: Zsolt Vasvari updated Gridlee and Bally/Sente driver to use new video timing code and raw screen parameters. Changed VSync to 59.185606 Hz.

- 0.58: Added Custom and Samples sound (bounce1 and bounce2.wav - partial).

- 0.37b16: Aaron Giles added Gridlee (Videa 1983). Analog sound hardware is unemulated.

- 25th May 2001: Aaron Giles sent a driver for Gridlee.


- Catch as many balls as you can.

- Shoot opponents as they pass overhead (watch their shadows).

- Avoid the charged squares YUMPERZ and FERGIES.

- Watch out for IGOR. He gums up your grid.
