I was looking for a Raspberry Pi case with shutdown and reset buttons for my custom Mega Drive Mini, using Blast16 and Raspberry Pi. And then, Retroflag released the MEGAPi Case. It is really faithful to the original shell, and the reset button and shutdown switch are really convenient (no idea why it’s so difficult to find Raspberry Pi cases with this funcionality).
I made Blast16 compatible with MEGAPi Case’s reset and shutdown scripts, so if you use the Raspberry Pi SD card image I’m about to release, you won’t need to do anything for these buttons to work. Reset and shutdown will work out of the box.
