This topic will give you a few different ways to remove injuries from the game, or modify them.
There are a few options we have:
1 - Remove them totally (just a regular check will occur)
2 - Remove injuries, but stop play, show player on the ground, and still give a penalty for the hit (if Penalties ON)
3 - Make all injuries only for the period
4 - Make all injuries only for the game
Option 1: Remove all types of injuries from the game (regular check will occur)
1 - Open ROM in a hex editor. Navigate to 14440 in hex, or 83008 in decimal.
2 - Change 66 to 60. This will branch over the injury code completely.
In a case where an injury would occur, now it will just be a knock down from a check.
Option 2: Remove injuries, but still show player on ground and give a penalty for the hit
1 - Open ROM in a hex editor. Navigate to 14450 in hex, or 83024 in decimal.
2 - Change 61 00 00 5A to 4E 71 4E 71.
This will skip over the injury type subroutine, while everything else will happen. I haven't tested this out to see if the screen will pop up with the injury information or not, but the injury will not be applied.
Option 3: Make all injuries for the period
1 - Open ROM in a hex editor. Navigate to 14536 in hex, or 83254 in decimal.
2 - Change 67 to 60. This will ignore the check for game injuries.
All injuries will now be for the period.
Option 3: Make all injuries for the game
1 - Open ROM in a hex editor. Navigate to 14508 in hex, or 83208 in decimal.
2 - Change 66 to 60.
3 - Navigate to 14520 in hex, or 83232 in decimal.
4 - Change 67 to 60.
All injuries will be for the game.
I plan on making a tool to apply these changes automatically.
