NEO GEO MVS Sound Issues
Ken Layton:
All the Neo Geo one slots are JAMMA. The 2, 4, and 6 slots are NOT Jamma, but rather they use the "MVS" standard. Visit www.hardmvs.com for more information.

hhmmm but the thing is... even when the JAMMA connector is UNPLUGGED(NO game attached) the PSU still makes the noise! Only with the MK board in does it not make the sound! Hhhhmmm I mean the only difference I see between the MK and the 1slot MVS is the -5V line.. what is my power supply retarded and NEED load on -5v???
Ken Layton:
Your power supply may need servicing. It might have some bad capacitors or bad solder joints.
raventy:
man its so weird that it works fine with MK board in... its like the power supply has grown custom to the MK and wont accept anything else! XD Being as they are $25 bucks.. I think ill probably just buy a new power supply rather than dealing with the hastle of opening this one up and trying to repair it. Do you think using the machine with its current messed up power supply could cause damage to it? I wouldnt want to risk damaging the MVS stuff I just got and hooked up to it. :)
tommy:
id say if one board works and another dosent then its the pcb or how its hookedup, its not fully compatible to you cab in some way are those the only 2 pcbs you have
