There are 19 endings in the game, and over 50
pictures in the photoshop. Check the values in
the "FLAG3" file first: if the beginning says
"ALLPIC.MES", and byte $6B is already $11, then the
photoshop has already been maximized. If it hasn't,
or all the endings aren't showing up, change bytes $61
through $6A to the value $11, except $63 can be $10 and
not miss anything. Now change $6B to the value $01.
When you next run the game and view the entire photoshop,
you will get a final screen with a Japanese text phrase,
and the FLAG3 file will be modified to maximize the
photoshop. There are other ways of getting to see only
some of the pictures, but I figured you can always ignore
the boring stuff if you are guaranteed to see ALL the adult
stuff as well. Note that any changes to the FLAG3 file
require a binary file editor.
