Hello Mastermind_X.
I implemented your fancy knowledge number 3 (two musics in one event) successfully in FireRed US BPRE. However, I use Pokemon Ruby as my base, so I've been trying to adapt it to Ruby. I've found all the offsets to change and found all the pointers except for one. I could not find the one that's like "func_setvar"

Here is what I have changed so far:

This is what the main ASM function looks like after I changed all of the pointers:

FE B4 05 1C 1B 48 20 49 00 F0 33 F8 00 22 90 42
0B D0 03 88 1B 49 8B 42 07 D0 AB 42 05 D1 17 48
19 49 00 F0 26 F8 05 88 12 E0 13 48 16 49 00 F0
20 F8 00 22 90 42 0B D0 03 88 12 49 8B 42 07 D0
AB 42 05 D1 0E 48 10 49 00 F0 13 F8 05 88 FF E7
28 04 FE BC 0D 4A 04 B4 0D 4A 0E 49 40 0B 40 18
83 88 59 00 C9 18 89 00 89 18 0A 68 01 68 10 1C
00 BD 08 47 30 50 00 00 33 50 00 00 31 50 00 00
34 50 00 00 FF FF 00 00 55 E4 06 08 13 DF 1D 08
5C 54 45 08 8C 54 45 08 00 00 00 00 00 00 00 00

The bolded is what I changed (I changed the variables for various reasons)

Anyways, do you think you can help me out? Me and ZodiacDaGreat have been trying to figure this out for a while now. With what I changed the game freezes right after the boot screen.
