On the page it says that in power-up state, the bank mode is 2, which is 8K. While I don't have any experience with testing out hardware mappers, I do have some ROMs that have this mapper and both don't have valid interrupt vectors in the first 8K.

Bank mode in Powerup State
I can also confirm that the Mapper implementation works (at least for the Contra 16 100-in-1 ROM) only when the starting bank mode is 0, not 2.
