Got the defensive playbook size increased. It only goes from 1 to 2 pages, but it's better than just the 1. It's still buggy with custom plays though.
I also noticed a bug with the offensive extended playbook when using custom plays - if you press B (flip play button) on page 2, it will switch to the custom play page with them flipped. It still works, it's just not supposed to happen.
I'm thinking about how exactly we can load the custom play data into the RAM where it needs to go (starts at address 802ADF20). An issue I foresee is that there are many addresses for the custom plays, so I don't know if there's anywhere in the ROM that has enough empty space to stick this data. The alternative is to try and make the game write the memory pak file into the RAM immediately instead of waiting. If multiple people made the own plays on different memory paks, we would still need to combine them into 1 mpk file which could then be loaded into the RAM. I guess it's not the end of the world if we can't get the mpk data directly in the ROM, but it would be nice as we wouldn't have to load the custom playbook each time.
I really want to see if the play data is the same for 2001 now... I may try and import a few of those plays to see. If so, we maybe able to get in enough default plays to make a 6th offensive page and 3rd defensive one.
Here is the code for the extended playbook/timer in case you're curious how it was done.

Edit: got pretty much all the bugs figured out! Fixed the flipping play issue and got custom plays working perfectly for defense. I changed how the extra plays were added on the defensive side too and changed the code to represent it.
I think the only thing left is making the custom playbook work for players 2,3,4.
