Saved Game Hex Cheat Codes (the only way to cheat in episode 16)

Start a Super Bubsy game, hit Escape, choose Options, save a game, edit the
saved game with a hex editor. Byte 18 hex is the number of lives. Enter
any hex number up to FF hex. The largest number displayed during the game
is 99, so if the the value entered is 64 hex or higher, the 99 will
continue to be displayed until the actual number of lives is decreased
to below 99. Byte 20 hex is the episode number. Enter any hex number up
to 14 hex. 13 hex is the last playable episode (and the one in which no
cheat codes will work). 14 hex is the ending sequence. Bytes 34 hex and
35 hex are the time remaining. These values are repeated in bytes 38
hex and 39 hex (reason unknown). Apparently the highest value accepted
is FF hex in bytes 34 hex and 38 hex and BA hex in bytes 35 hex
and 39 hex. Putting very high values in these locations will result
in items from the game being displayed in the time remaining area
instead of numbers and a much larger time bonus at the end of the episode.
