PC build crashes on Start screen when pressing Z; background shows pink/black checkered tiles, error address

[ALttN]

Describe the bug
Game-crashing bug on start screen when interacting with Mario's head. Pressing button mapped to 'Z' twice causes the following error to be displayed:

"Exception occurred at address 0x00000001400D5971 with error code 0x0000005:
Segmentation Fault - The game tried to read at address 0x0000000011549F38.

To Reproduce

1. Wait on start screen with Mario's head
2. Press button mapped to 'Z'
3. Game will show graphical glitch instead of mural of screen tiles
4. Press 'Z' again to cycle screen tiles off, game will crash.

Expected behavior
Expected normal behavior of user interaction commands from game based on original software

Fixed, will open a PR later since I took the chance to improve EXTERNAL_DATA while at it.
