Okay wait, I'm a little confused, so I was connecting the YMZ slot directly to the Gimmick cart, but you intended directions for the Gimmick cart to go into the HFX4 catridge slot (w/ ymz connected to corresponding Gimmick pins)? I know this is a noob question but what's an example of tying pin 14 t...

That sound is the "sound generation control is powering on with random values" ... all it indicates is that nothing's ever being written to it. I see that makes a lot of sense, thanks! Sorry if I'm beating a dead horse, but I was thinking for a solution, could it possibly work to connect ...

I just discovered that the Gimmick! cart plays that same noise (when in an HFX4 cartridge slot) when the cartridge is not inserted correctly in my AV Famicom upon turning it on. Maybe it needs some kind of correct data input keeps this noise from happening?

Gimmick, when placed in one of the HFX4 expansion cartridge slots produces either: -Nothing -intervallic popping (more rare) -constant noise from the 5B's random noise generator -crescendoing noise from the 5B's random noise generator that when it reaches max volume stops and is silent until Famicom...

Well, ok, as a final guess, I'd hope something like the following is true of the YMZ294 socket: pin 1 = /WR = connected to ground or to R/W (cartridge pin 14) pin 2 = /CS = connected to /ROMSEL pin 3 = A0 = hopefully connected to CPU A13 (cartridge pin 34) pin 4 = Vdd pin 5 = SoundOut - probably no...

Yeah, you need to tie Gimmick's CPU A14 (pin 35) input high and connect Gimmick CPU A13 (pin 34) to YMZ294 A0. You "should" tie the other input pins high or low, but that might not be necessary. Sorry, what does 'high' and 'low' mean? Edit: and 'tie'? Just want to make sure I understand a...

Sorry to sway the conversation, but I just used a breadboard to connect Gimmick! to the YMZ294 port and my set up didn't work. I put D0-D7 in the right places, the Gimmick Audio to RF (pin46) to YMZ Sound Out (pin5), Gimmick M2 to YMZ Master Clock (pin7), the ROMSEL to CS and WR to R/W. I also put t...

I based my 5B mixing on Rainwarrior's Gimmick! cart and bumped the volume a tad (maybe .4 dB) for preference Yeah I had to bring mine to the same level since I had been playing back my FTM in FT and NSF in NSFPlay. Both levels seem pretty similar. For example, any expansion game when used on an AV ...

Ah I see, so there really isn't a set standard
What is FT's mixing based off of?

I might have bumped the volume of the YMZ just a tad (for preference, it's still way under what it would sound like on an AV Famicom) Hey TrackMan, I think your settings on the YMZ294 is based on how FamiTracker and NSFPlay mixes SS-5B. I just wrote a piece for the 5B and noticed that the balance o...

This is great, I'm really excited to see this.

I bought a couple Sunsoft games in preparation

Your problem seems worse than mine. I use a Youkai Dochuuki cart for my N163, and I get a similar nasty hum, however it goes away permanently upon playing any N163 NSF. I don't think the cartridge is an issue concerning the low 55Hz A, because I made an 8-channel N163 NSF that works fine without th...

The N163 always puts out that high frequency noise when enough channels are enabled. Because it's so high frequency, it's easy to filter out, though. Through RF out it's not very noticeable, though you said you're using an AV famicom? I don't know if that one has any kind of lowpass filter, but als...

The knobs/chips: YMZ - YMZ SLOT4 - RP2C33 SLOT3 - VRC7 SLOT2 - N163 (varies according to channel needs) SLOT1 - MMC5 (might be a little off since I'm using an NES cartridge for the expansion). Might change when I get a VRC6. These are all mixed with the main "EXTERNAL VOLUME" pot perfectl...

@also rainwarrior: It's too bad TNS-HFX4 doesn't take 2a03 mixing for YMZ/5B into consideration, which is what you were mentioning earlier which makes 5B's sound subtly unique (compared to YMZ294) right? Maybe copyNES is the best solution afterall... I think you can safely ignore that difference, t...
