+ Super Speed Race Jr (c) 1985 Taito
+ driver by Tomasz Slanina
+
+
+ TODO:
+ - colors (missing proms?)
+ - dips
+ - proper video hw emulation
+ - controls (is there START button ?)
+
+HW info :
+
+ 0000-7fff ROM
+ c000-dfff VRAM ( 4 tilemaps (4 x $800) )
+ e000-e7ff RAM
+ e800-efff SCROLL RAM
+ f003 ??
+ f400-f401 AY 8910
+ fc00 ??
+ f800 ??
+
+ Scroll RAM contains x and y offsets for each tileline,
+ as well as other data (priroities ? additional flags ?)
+ All moving obejcts (cars, etc) are displayed on tilemap 3.
