+ -= 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
+
+Blomby Car is said to be a bootleg of Gaelco's World Rally and uses many
+of the same fonts
+
+Waterball
+
+Check game speed, it depends on a bit we toggle..
