* Full Protection. Only the clones are working.


- 0.143u1: Tafoid fixed problem with keyboard control in clone Oigas (bootleg). Removed 8-way Joystick in all sets.

- 7th August 2009: Smitdogg - Thanks to D. Beneke we got a box of PCB's from a dealer in NY for pretty cheap. I've dumped all. One is a is a Gigas bootleg that looked interesting until I pulled the plastic cover off a chip and found it wasn't hiding anything cool.

- 0.131u2: Nicola Salmoria added MC-8123 key (317-5002) for Gigas. Of course the game still doesn't work because the program ROM is missing. Changed description to 'Gigas (MC-8123, 317-5002)'. Changed maincpu rom address from $10000 to $4000.

- 0.131u1: Andy Welburn added original Gigas (Sega 1986).

- 0.105u5: Sonikos cleaned up the Free Kick driver and added 2nd button in Gigas and clone Oigas.

- 20th April 2003: Tomasz Slanina simulated the 8741 MCU protection in Oigas, so it is now playable.

- 0.66: Tomasz Slanina added Gigas (bootleg) (bootleg 1986) and clone Oigas (bootleg).

- 11th February 2003: Tomasz Slanina added Gigas and Gigas Mark 2 to the Free Kick driver.

- 5th February 2003: Guru - Gigas (Sega 1986) arrived from Taucher.
