Nanpa cheat codes:
The way to see the sexy pictures is to be in your
starting room, and click on the computer.
You should get a menu of up to 10 items, plus arrows.
When it is complete, the first 10 are girls' names I
guess, and pressing the down arrow will get you to 5
more (really 4 plus miscellaneous school girls) plus
a cancel option at the end. Using a binary file editor
to patch the file FLAG0 so bytes $68 through $CF, $E0
to $14F, and $151 to $1EF are all the value $11 will
turn on all the pictures for all the girls. Setting
byte $150 to $11 will cause the starting room picture
to disappear! However, setting all these values will
cause the game to lock up if you try to leave the
starting room! This is because you are basically telling
the game to marry you off to all the girls at once! So
look at the pictures, but don't do anything except exit
the game then.
