Editing duck shoot high scores

WACKY.DTT consists of 96 bytes divided into 4 lines 24 bytes long. Each line determines the name and score in Wacky Duck Shoot high score list. Each line follows this pattern:

First 16 characters (the name) can be upper case letters, numbers, spaces, or these characters: ! # & ( ) - , . ' ?
Next 4 characters are NUL (ASCII 00).
Next byte is any character, 0–255. ASCII value determines score (%=37, A=65, etc.).
Next 3 characters are NUL.

The name can be anything you want, as long as it only uses the characters listed above. Lines do not have to be in order of score: lower scores can be a line above higher scores. Here is an example of a score listing that would only be possible by editing WACKY.DTT as it would appear in the game:

PHIL             255
BILL & TED       0
                 34
---  NOBODY  --- 40

Here is what WACKY.DTT would look like, with a period (.) representing ASCII value 00:

PHIL            ....ÿ...
BILL & TED      ........
                ...."...
---  NOBODY  ---....(...

Notice that there are not actually any line breaks in the file, so it would look like this without wrapping the text:

PHIL            ....ÿ...BILL & TED      ........                ...."...---  NOBODY  ---....(...
