Nanpa cheats and cheat codes for PC

Hex cheat:
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 8 through ,  
to 4F, and 51 to EF are all the value 1 will 
turn on all the pictures for all the girls. Setting 
byte 50 to 1 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.
