- 04067 [Misc.] blktiger: Test mode doesn't work. (MooglyGuy)

Non-Whatsnew note: In my opinion, I feel that it's a reasonable assumption that whatever video ASIC or other hardware is used defaults to having at *least* the text layer turned on.  The game doesn't even attempt to write any video configuration registers apart from the bank reigster when booting with test mode turned on, which strongly implies certain default states of certain registers.
