Game's ROM.




MAME Info:

0.139u4 [Roberto Fresca, Dave Ormiston]


WIP:

- 0.139u4: Roberto Fresca and Dave Ormiston added Symbols (ver 1.4) (Advanced Video Technology 1985) and clone (ver 2.5). Symbols is a video skill game displaying a large red bordered box with a white grid of 5 rows across and 5 columns of symbols down. The object of the game is to line up the winning symbols either horizontally or diagonally in the shortest amount of time with the least amount of moves. The winning symbols are selected at random at the start of the game and displayed with a distinctive yellow color surrounding that symbol in each column. For 'HOW TO PLAY THE GAME' see source driver.

- 10th October 2010: Roberto Fresca - This time, a couple of 'most wanted' appeared in the scene... Arrow Bingo and Symbols. They are amusement/skill games from Advanced Video Technology. No PCB/schematics/datasheets/manuals, so just reverse-engineered the program ROMs to get them working. They run in a Z80 based hardware with an AY-3-8910 device for sound. The Z80 works with a couple of CTC and PIO devices in a daisy-chained interrupt mode. Here they're running without daisy-chain interrupts, so they are not playable ATM. Symbols: There are 2 sets (v1.4 and v2.5), but only the v1.4 is showing something.
