Nes Bubble Bobble GG Code Request

[Mario133]

Does anyone have a GG code that allows you to change the music that plays during each level of the game? Like say I want the secret song at the end to play through the game instead of the usual same old music everytime on every level :P

I've never heard of music changing codes, but I guess someone with knowledge could do it.

[Mario133]

Yeah I was unable to find a music changing code anywhere myself to but I'm pretty sure a GG code not made yet can make this possible.

[ReyVGM]

I don't know. I haven't found such a thing. Not even by accident, which is how I find most of my weird codes.

I still think it should exist under something other wise how is the music not coded in?
