Just noticed an odd issue with the KO countdown timer in Super Punch-Out and 0.137. The left half of the timer number is diplayed on the far left side; while the right half is on the far right. The number should appear in the center of the screen (as it does in bsnes and real hw).
It's easy enough to replicate - just start the game and wait about 3-5 minutes through the attract mode/demo. Eventually the timer will appear.
