Infidelity, you did a great job with this hack and I can see a lot of work went into it. I too have always wanted a 2-player mode in the NES version of Tetris.

In your post, you mention the hidden 2-player mode located at $00BE in the original, non-hacked ROM. In that unfinished 2-player mode, there is one feature that is not present in your hack, and I'm wondering why you chose not to implement it. In the hidden mode, if one player achieves a double, a triple, or a Tetris, a number of garbage lines appear at the bottom of the opponent's screen. This is analogous to the garbage blocks that fall from the ceiling when a player achieves a combo in SNES Tetris Attack, and in my opinion, it is the thing that makes the mode truly interactive between the 2 players.

(The garbage lines are full except for one straight line gap through them, which makes it makes it possible for the opponent to exact revenge by achieving his or her own combo by simply filling that gap with a straight Tetrimino.)

I would be thrilled if you would implement something like that in Tetris Zero, although I do notice the word "Final" in the thread title here....

---------------------------------------

For those of you interested in trying the unfinished 2-player mode that exists in the original ROM, here's what to do:
1. Read about it in this article at Meat Fighter, and make sure you're still interested. The mode is unfinished! The colors are messed up and the 2nd player's screen is partially obscured!
http://meatfighter.com/nintendotetrisai/#2_Player_Versus
(I am not the author of that article, nor am I nearly as knowledgeable as he or she is.)
2. Acquire a ROM of the regular, common Nintendo Tetris (US) for the NES.
3. Download the emulator FCEUX for free at http://www.fceux.com/web/home.html
4. Open the Tetris ROM in FCEUX and while it's running, click on Debug -> Hex Editor...
5. You are now viewing the NES memory.
6. Click on File -> Goto Address....
7. Type "00BE" (those are zeros, not ohs) and click OK.
8. What should now be highlighted is the 15th entry in a row labeled "0000B0". The value at that entry should be "01". If it isn't, something has gone wrong and may God help your poor soul b/c I have no clue.
9. Don't click anything! Type "02" to change the "01" to "02" (as in, there will be 02 players).
10. Play the game.
11. The number of players will reset to 01 after a single game is played, but you can just manually set it back to 02 again.
