- TABLE (as in the LEVEL TEXT offsets) -

00-DF - I dunno
E0 - MUSHROOM CUP
E1 - FLOWER CUP
E2 - STAR CUP
E3 - SPECIAL CUP
E4 - MARIO CIRCUIT
E5 - GHOST VALLEY
E6 - DONUT PLAINS
E7 - BOWSER CASTLE
E8 - VANILLA LAKE
E9 - CHOCO ISLAND

This selects an offset from an offset category. For example, if you change E4 in 1CA80 to EB, it will show BATTLE COURSE 1 instead of MARIO CIRCUIT 1.

and if you change E0 in 1CA74 to EC, it will show RAINBOW ROAD instead of MUSHROOM CUP.
