+Time Limit (c) 1983 Chuo
+Progress (c) 1984 Chuo
+
+driver by Ernesto Corvi
+
+Notes:
+- sprite colors are wrong (missing colortable?)
+- driver should probably be merged with taito/roundup.cpp (and taito/suprridr.cpp)
+- unused color bank for tilemaps? (colors 0x10-0x1f & 0x30-0x3f)
+- verify clocks, they're currently borrowed from thepit, maincpu clock
+ used to be 5MHz in older MAME versions but that's doubtful
