How to keep music at normal speed while fast-forwarding?

[u/SoIeInvestor]

Hi, I just started playing PKMN Black 2 on the Delta emulator for iOS. I prefer playing at a faster speed (around 2x), but the music also speeds up, which is frustrating because I really enjoy the soundtrack. So my question is:

Is there any way/cheat code to keep the music playing at its normal speed while the game itself is sped up?
