-= Blomby Car =-
driver by Luca Elia (l.elia@tin.it)
Main CPU : 68000
Video Chips : TI TPC1020AFN-084 (= Actel A1020A PL84C 9548)
Sound Chips : K-665 9546 (= M6295)
To Do:
- Flip screen unused ?
- Better driving wheel(s) support, merge with World Rally implementation
Blomby Car is said to be a bootleg of Gaelco's World Rally and uses many
of the same fonts
(Update: it actually is a bootleg of World Rally by looking how much
similar the two HWs are, down to the dipswitches!)
Waterball
Check game speed, it depends on a bit we toggle..

The game has fonts identical to World Rally and obviously Blomby Car ;)
