Noise notes are higher pitched than normal

I was playing Islander on my Miyoo Mini Plus, and I noticed that the step sounds and break sounds are higher pitched than normal

This is what it's supposed to sound like:

And here's what it sounds like on the Miyoo Mini Plus (Recorded using Line In, but still sounds the same through the speaker)

I am using the same cartridge on both the Miyoo Mini and Pico-8

Here's a link to Islander on BBS, you can get the cart I used there
