MAME Info:

SETUP:

- This is actually a Keno game (slightly modified Raffle/Bingo/Tombola game).

- First off, select the bet amount with the BET button.

- Then choose between "SELECT 10" button (pseudo-random) or user-defined numbers,by pressing the desired number with the numpad then "select" (enters the decimals first then the units, if three or more buttons are pressed the older pressed buttons are discarded, i.e. press 1234 then SELECT, 1 and 2 are discarded).

- Press "CANCEL ALL" to redo the numbering scheme.

- Once that you are happy with it, press START to begin the extraction of winning numbers.

- If you get at least 2-4 numbers out of 20 extracted numbers, you win a prize and you are entitled to do a big/small (double up) sub-game.


WIP:

- 0.143u7: Roberto Fresca fixed default dipswitches and DIP locations in Big 10.

- 0.136u4: Angelo Salese implemented irq ack to Big 10.

- 0.133u1: Changed Z80 CPU1 clock speed to 3579545 Hz and AY-3-8910A to 1789772 Hz.

- 0.129u3: Angelo Salese, Roberto Fresca and Tomasz Slanina added Big 10 (unknown 198?). Roberto Fresca cleaned up and remapped Big 10 inputs. Updated the game notes. Added other minor changes.

- 22nd January 2009: Roberto Fresca - I really love when we start something about a rare game, knowing nothing about the hardware or the game itself, and we get the game working with all bells and whistles... This time I worked with Angelo Salese and Tomasz Slanina on 'Big 10', and got this rare Keno game working.
