NEO HYPER 64 QUESTION--SOUND MOD

Hello everyone,
I am getting ready to buy my friends Neo Geo Hyper 64 system. I heard that there is no sound on the board, only speaker outputs.

Is there anyone who can tell me how to mod the system, so that sound will play using MAS SYSTEM supergun? Has anyone ever did any modification on this actual system?

Thanks for listening,
Darrick

Is modding really worth it on this system?

Looks like you are getting a Rev1, be careful as it might need an extra psu. Check this thread and that entire forum:

If I were you I would just get a Rev2 motherboard that should work straight away. Still, wiring the sound directly from the board shouldn't be that difficult.

The rev. 1 board does not need an extra PSU!

You just need a harness to hook from the board directly to the speakers. And another harness to hook extra 5V and GND wires to the existing PSU, and it is not sound related just the way the rev. 1 board was designed. Granted rev. 2 fixes the design mistakes of rev 1 with just a simple JAMMA connection, and it has the JAMMA-MVS switch.

Sorry, I meant there was an extra +5V connector that needed to be hooked, it was my mistake to mention an extra psu.
