Bug Report

What's the issue you encountered?

• Describe the issue in detail and what you were doing beforehand.

I was attempting to recreate SCP - Containment Breach on the 3DS using entirely new code written in C, and the sound code i have been trying to implement causes an odd issue, where it seems like it's trying to read memory beyond the sound effect on shorter sounds.
