Pretty sure the transparent design was to deliberately block the power switch on the original Game Boy (aka the DMG-001), so yes that should be the sign to look for when determining GB/SGB compatibility.
I hear the only exception is Robopon (which has a custom case because it has a battery-backed alarm feature).
