Sound Initial Code while choosing the weapon
Written by Insectduel
In the memory where the ROM offset is located at x78010 to x7A00F (Bank $3C by $2000).
Change $992A and $996C to the JSR initial code to the location where the empty unused memory is. Then enter the following below.
- 20 XX XX JSR $XXXX ; Location to the Sound ID Code.
- AD 38 01 LDA $0138
- 60 RTS
- A9 2E LDA #$2E ; Sound ID to play
- 4C BE F6 JMP $F6BE ; Init Sound
That way the sound will always hear when you choosing the weapon menu.
