1. Mario Kart isn't worth it without Rainbow Road. 2. I don't believe Rainbow Road exists unless it has a theme that doesn't cause ear rot. 3. The theme for "Rainbow Road" in MKSC causes ear rot. Is there a hack or cheat I can use that changes Mario Kart Super Circuit's "Rainbow Road" theme to an actual Rainbow Road theme instead of that ear rot bullshit that ISN'T appropriate? Or..... How about a hack that changes ALL the songs in MKSC to something else? Anything other than the official songs. All of them are ear rot. Except the theme for Boo Lake. That sounds fucking cool EDIT: I can't play this game until that Rainbow Road theme is changed. It's so bad I can't even make myself try to unlock Rainbow Road. I say try because the songs are so bad my ears bleed just at the thought of them and I can barely even do anything past the headache the thought of the songs in this game give me.
WOW, you know it's a GBA game, gba games don't have the best sound you know. That was then this is now, it has changed.
I wasn't able to find any program that can replace the music in a GBA ROM. Your best bet, honestly, turn off the music.
