Super Punch-Out!! (SNES)

The fourth game in Nintendo's legendary Punch-Out line (fifth if you count the modified NES Punch-Out).

Sound Test


Hold L+R on the second controller at the opening Nintendo logo for the game's sound test.

Super Punch Out Error Screens
For some reason the text "SuperPunchOut!!" gets written to RAM at.

This is probably related to that, if $7E07F0-$7E07FE reads:

53 79 73 74 65 6D 20 45 72 72 6F 72 20 21 21

aka

System Error !!

This screen will be thrown up:



When $7E27F0-$7E27FE reads that same text this gets thrown up:



41 6C 72 65 61 64 79 20 54 72 61 6E 73 21 21

aka

Already Trans!!

gets written to $7E47F0-$7E47FE at start up as well, not sure why though.

You also get a very informative error message if on game start/restart the carry flag does not get set (CLC : XCE : BCC $2A) as well as if the direct page register is non-zero:
