[snesmini] Shutdown via menu item possible?

[mrgone]

I'd like to shutdown the snesmini via a menu option so i can remotely turn off the power.

this doesn't work:

but it results on a error c7.

also, there is no /bin/sh (i know what busybox is! shouldn't it be symlinked?)

does anyone have a viable solution?
