I wasn't able to make most of the codes you wanted because either too much time involved, or couldn't figure it out. I was able to make your number 1 choice though, and lots of other misc codes. I didn't actually test the "disable domination rule" code (not enough time), but it should work.
A few notes:
Please let me know if you needed the master code or not.
I made some codes for Martinez that change some of his stats. If you want, you can test them to see if they change his playing abilities in the game.
I didn't make any codes for balls or outs because it was going to take too many codes to make it work right. I did make some strike mod codes.
Let me know if you have any problems.
