-GymTrashCans3c:
-; First byte: number of trashcan entries
-; Following four byte pairs: indices for the second trash can.
-; BUG: Rows that have 3 trashcan entries are sampled incorrectly.
-; The sampling occurs by taking a random number and seeing which
-; third of the range 0-255 the number falls in. However, it returns
-; that value to the wrong register, so the result is never used.
-; Instead of using an offset in [0,1,2], the offset is instead
-; in the full range 0-255. This results in truly random behavior.
