#!/bin/sh in prepare_openmaxil_backend not in the first line

[MrCustomizer]

Please move the line #!/bin/sh to the beginning of the file prepare_openmaxil_backend. Otherwise, you are not able to run this script from inside other shells, like for example fish.

This was intentional. Other shells are not supported. If you want to use those it may work but the only supported one is that.
