custom edit/rebuild from Bortis n64 Amp https://github.com/borti4938 thx Borti
features:
-composite sync on Video -> Multi AV (Pin 9) -> compatible with every RGB Cable
-THS7374 Amplifier 4 channels
-LowPass Filter (enabled by closing the jumper)
-composite sync filtered by 330uF
Makes it easier to use RGB cables with n64 (pal/ntsc) rgb mods or ntsc consoles with vdc-nus chip.
(Consoles with denc,mav or avdc nus need also a rgb mod.)
