Inspired by a youtube video I watched yesterday (maybe BBB, or PGH Forrest?). The title says it all, Falco may not have the aim of a stormtrooper but at least he can sound like one.
This is a mEX sound bank. To install download mEX, open your ISO, click on the Sounds tab, and replace the falco.ssm file with the download file.
Slippi compatible.
Can you post a link for mEX
