Custom Samples and SFX

[Mentlegen]

So i've been well on my way with the MSU1 recently and wondered if there was a a way to replace the current SFX with new custom ones.

This post provides some info but im unsure how i can go about editing them. http://forum.metroidconstruction.com/index.php/topic,3184.msg41819.html#msg41819

Projectiler has the ability to change a SFX from the given library so i was wondering if it was possible to edit these libraries.

Thanks for the support.
