Fix Y Button Bug Allowing Checked Players to Instantly Stand Up

---

Problem:
When a player is knocked down, pressing the Y button causes them to get up instantly. This behavior doesn't occur on GENS or the previous version, NHLPA 93.

The knocked down player should stay down for 3 seconds as intended.

Solution:

The Y button performs a 'Hook / Hold' animation when you don't have the puck. The existing code already prevents "Hook/Hold" if your player is "Speed Boosting"

• To improve this, we add an additional check when the Y button is pressed to determine if the controlled player's animation is in the 'Knocked Down' position.
• If the player is knocked down, exit the routine without performing the "Hook / Hold" animation similar to "Speed Boosting" code.

Technical Details:

The code below is executed when the Y button is pressed without the puck. 

Code:

1. Load the selected player animation/action, 0 = Standing, 1 = Knocked Down or Passing, 8 = Slapshot, F342 = Speed Boost
2. Check if the player is knocked down
3. If the player is knocked down then branch to RTL (Exit).
4. If the Player is NOT knocked down then continue back to the original code.

New Code:

Download the patch tool to create your own ROM or patch an existing ROM.

Hex Version:

1) Replace old hex value with new hex value.
