Add hash to manifest for remaining cartridge based systems (#1536)

This originally added the N64, but after inspecting remaining
cartridge/card/fixed ROM based systems I have also added the additional
four so that hash is available in manifest. This should complete adding
this info for these types of consoles.

N64
Gameboy Advance
MyVision
SG-1000
Sufami-Turbo
