Installed a transparent smoke shell by #retrogamerestore on my spare #nes & then installed the #nintendrawer. Happy that the #powerpak works 100% now. Assuming the expansion audio pcb was making the powerpak glitch with the Nintendrawer.
Expansion Port Sound Module or #EPSM; it lets you play expanded audio from #jpn#famicom#carts &/or #roms. Installs onto the unused port on the bottom of the #NES. I need to update my old #powerpak w whatever is the latest firmware. If not I can always play my actual #fami carts via an adaptor.
