MISTAKES TO AVOID

THE BIG ONE:  Accidentally pasting hex code into the text area of the hex editor, or copying text data from the editor instead of hex data.

Player names and attributes:
1.  Adding a player name, but forgetting to add attributes for him.
2.  Deleting a player name, but forgetting to delete his attributes.
3.  Entering a player number from 1-9 without a leading 0.  You need to use 01,02,03,..09.
4.  Having too much data.  If you have more than 40 teams, you probably need to start worrying about how much data you're using for player names.

Lines:
1.  Entering a number in the lineups or player attributes without a leading 0.
2.  Having a player index in the lines that doesn't have a corresponding player.

Copying hex data to ROM:
1.  Pasting hex data into the text data side of the hex editor.
2.  Updating the team data in the ROM, but not updating the Team Pointers.

Number of teams:
1.  Removing teams, but not lowering the Number of Teams data in the ROM.

Playoffs:
1.  Every team that is allowed to be in the playoffs (you need to set 3 values in the ROM to say how many teams to allow) needs
    to appear in at least one playoff matchup
