CPS2 A-Board Volume

[ekorz]

I have issues with my CPS2 board where it's only outputting through 1 channel. I've tried to lower the volume all the way down and bring it back up again for stereo but I still get almost no audio out of the left channel. I can hear a little bit of it.

Try booting the pcb while holding down the volume button (can’t remember which direction, try both!). That resets the digital amp.

I got this memory issue cropped up in the last couple days in my big blue cab I've just ordered a new super cap, while powered on it's receiving voltage but when the cab is off the voltage is dropping away quite quickly on the cab the sound goes back to 0 after about 1 hour of the cab being off, this is the first time I've ever experienced this in all the many many A boards I've used over the years, will see if it fixes it.

I've recently done a board conversion from Xmen Vs SF to Xmen COTA and had a bit of an issue getting the B board to work with an encrypted set of roms what with so many crappy ROM sets out there, so had to seat and unseat the board a few times, hope I haven't damaged the A board in the process, it works ok sound and graphics wise and no bent pins etc
