Hello,
would like to recreate the battery patch for SunA's Hard Head. Does anyone know if the schematics exist on the internet?

there is no battery in SuNA 8bit games,
i have stripped one of those modules in the past.
dont trust everything written in mame's sourcecode.

Hey, there is no much info about this game. (also not much live )
Mine has no sound, caps look good, changed amp and both 324´s did not help.
Any idea where to start?
I kinda like the gameplay

Wow, thank you forum for simply existing!
I did check the pictures and something was just wrong.
The previous owner did put the 1182H the wrong way and it exploded.
I did replace it exactly where it was.... did not know about any repair attempt
Switched, works

with some amps there are 2 versions, the normal one and a mirrored one - so maybe he got mixed up.

Exactly, 1181/1182 are mirrored.
Think it blew up and he stopped the repair.
