Here is the wires connected. on a other thread it was said q sound has to go to a q sound amp. im running it to a blast city amp. is this the issue?

no, it does not require you to use a q sound amp. q sound is stereo but stereo is not q sound. q sound is a proprietary form of stereo designed for cps1.5 games only (and later, cps2 games). the games that utilize the rca connectors on the multi pcb are for the cps1.5 games only, not the cps 1 games. cps1 games do not have q sound, they use dual mono from the jamma edge. cps 1.5 games run audio from the q sound chip to the rca connectors on the multi board. to get the real experience of q sound, u will need a q sound amp like in a capcom impress or big blue and will have to somehow bypass the amp inside the model 3 power supply of your blast. it is very similar but also different. regular stereo from the amp in your blast is good enough and will be present if you run a cps1.5 game such as caddys and dinos but not if you play a game such as 3 wonders. for a cps1 game you will need to connect your audio connector on your blasts harness into the jamma edge to get sound. i hope that clarifies.

also, just to verify, is this the fan header?

yes
 
Thats exactly what i thought. does this mean my darksoft has an error? as soon as i hook it up i get feedback, like in punisher. or is there a setting i need to adjust. i know how to hook it up on the cab side, i am using it on my cps2.

you can try CAREFULLY reseating the q sound module and trying again. i dont have any advice beyond that but someone else will, im sure of it.
 
Well, your QSound and Reset wiring look correct to me in your photos. Here are a few possibilities.

1) Your amp might not be set to stereo audio input. The mono JAMMA audio for CPS1 games is amplified while the stereo RCA port audio for CPS1.5 is line-level, so typically there is an input switch you change on the amp to swap between the two options.

If you have another device with stereo RCA cords (like a console) connect it to your amp and see if you get stereo audio output with it.

2) the ROM set on the SD card might be missing the necessary file to trigger the Multi to switch over to QSound. You are using a ROM set specific to the Darksoft CPS1 Multi, correct? I assume you are since it sounds like you’re switching between other games just fine, but I wanted to ask.

IT's a left over that provides 12V. Can be used for a 12V fan.

That is my feeling too. So just to make it clear. Do you hear sound in CPS1.5 Qsound games over Jamma? If you do, then your multi setup is working perfectly and the problem is on the cabinet side 100%. Maybe a stupid question but did you try adjusting the volume pot on the multi?

I did. but i will try again.
 
well i am dumb. I was testing on King of dragons, which isnt qsound. when testing on CD and punisher, no sound over jamma. i started to mess with the volume and pressed down on the q sound chip and boom, no more feedback. now its working.

i just edited my last post. after pushing on the q sound chip, the feed back is now gone. ill do more testing and see if the issue is intermitten
 
Hello - finally getting my 2nd CPS1 Multi all put away inside my Jasen case (I will just take it all apart when the Dual Oscillator board arrives, if it does).

Having some weird differences. The first one, 12mhz dash board, unmodified C board - all good. When I rewrite a game, it takes about 36 seconds to erase the flash, and about 18 seconds to write SF2: HF.

On the 10mhz board, unmodified C board - its MUCH faster to erase the flash - same game, SF2: HF. It takes about 8 seconds to erase the flash and about 18 seconds to write SF2:HF (same).

Is the difference in flash erase speed meaningful? The reason I ask is that on my 10mhz board, I cannot get Strider to load. I am using the exact same rom files as I am for my 12mhz multi.

Thanks!

EDIT: Figured out the Strider issue - I had Dip Switch C3 set to ON, down on the A board. After I turned that off - all good.

I am now just curious about the big difference in flash erase speed.

Matt
