Forgot to link the Bandcamp...

https://cowtonguetacorecords.bandcamp.com/

and the blog: http://blog.cowtonguetaco.com

Some nice tracks in there! I run a tape label... could be interested in doing a short run (5-10 copies). Would just be the NES LP though, as the rights issues with compilations are too hairy to get into.

http://cowtonguetaco.com - have a look and let me know if interested! stephen [at] cowtonguetaco.com is probably the best way to discuss the particulars.

Real nice. Elizabeth's loop lead chip sound ftw. What is that?

Nice work.

it's probably got SOME noise. even on the better of my two modded DMGs there's a very subtle hiss that you might not notice without headphones and/or really good ears.. i 've had really good hearing for years, so i tend to notice sounds a lot of people might miss.. hell, i used to be able to hear if a CRT tv was on (while just set to an input with nothing in it, so black screen no audio) by the slight hum from 25 feet away through a closed door

Yeah, this! The noise I get isn't audible until I am multi-track recording, but when you hear the tracks in isolation, or as part of an overall mix it is really obvious. Definitely requires a gate to get rid of it.

I feel you on the CRT thing. That high pitched whine used to do my nut in.

Can the backlight cause buzz in the pro sound output (and the normal headphone output as well for that matter) ? - If, yes. How could this be fixed ? Would isolating cables inside the DMG with electrical tape and use heatshrink tubes  be sufficient ?

I believe that it's possible that a backlight mod could add an extra bit of buzz, but I'm not sure how to fix it. Heatshrink tubes and electrical tape wouldn't make any difference as it'd be an issue with the circuit itself that would need remedied.


What advantage do you get from the RCA mod to your Gameboy ? Some of the most famous chip musicians use this mod and their songs sounds effectively really crisp and good...

The only advantage you get is the ability to use RCA cables, which have jacks that can be a bit less prone to pulling out accidentally, but that's it. There isn't any difference in audio quality between them and the minijack if done correctly.


Also curious about how to acheive that noise free Pro sound mod. Should you like clean up the gameboy internally all over with isopropyl alcohol?

I'm not sure that would matter. As Psynaptik mentioned, it could be a cold solder joint somewhere that's causing more of a buzz than usual. I still don't believe a completely noise free prosound mod is easily attainable. smile

I have to say that I don't get any noise at all on my 2 DMG pro-sounds, and they're both pre-pot. So getting a clean signal is NOT a pipe dream!

No noise at all? Would love to know how you managed that!

I don't get much noise from any of my DMGs, but there's definitely a buzz present when there's silence on any of the channels. To find any that really has no noise floor at all doesn't seem too likely, and is definitely rare at best. Either way, what I meant above was that there isn't much point in worrying too much about achieving perfectly clean audio given the nature of the device. It comes with the territory.

Hiya!

• Firstly, when I connect a minijack into the prosound output of my Game Boy and plug it into my mixer, the internal speaker of the Game Boy still plays. Does this have any drawbacks in terms of audio quality etc. ?

It shouldn't make a difference. When I first started modding I removed all of the speakers in my early DMGs, and now I wish I hadn't, as they are actually pretty handy for quick monitoring/checking things are playing when troubleshooting etc. I'd leave them in.

• Secondly, the ProSound output is really good, but the left channel has this tiny tiny hiss noise that's coming through.. Which becomes more prominent when applying effects such as reverb in post production. Is there something I could do to 'tidy up' the prosound mod to make the output signal cleaner ?

Just the left channel? Count yourself lucky! big_smile Seriously though, I wouldn't worry about it. Apply a noise gate or notch filter on the frequency and that should help, but trying to get a pure clean sound is a fool's errand when using a DMG. IMHO anyway.

• Thirdly, I bought my backlight kit from NonElectronics and it's the V5 of his standard backlight. I tried to e-mail him several times two years ago and ask about the proper solder points to use because I just picked two points from a video tutorial I saw on youtube that was for an earlier version of the backlight so I'm not sure if it's the optimal ones.. I'm wondering because the intensity of the backlight decreases slightly when I push play in LSDJ. Is this the case for you other chipmusicians as well ?
(The two points I used are the ones just below the screen, on the same board as the screen.

Doesn't really matter what points you use. The dimming of the lights is a bit irritating at times, and I'd be curious to find out if there was a way around this, but probably not. It's not just you that experiences it anyway. It gets more pronounced if you have low battery, fwiw.


CarrieStronggrog wrote:

Oh and by the way, the solder points for the Pro-Sound mod haven't changed right? I mean there hasn't been anybody else that have discovered a better way to solder the mod ?

Nah. Post or Pre-pot. Your choice. I don't really mind either way now - both have their up and down sides. Post pot is good to avoid dodgy old scratchy potentiometers, but having a line level trim can also be useful.

Picture of the side:

Forgive my crappy drilling. The vice wasn't tight enough and the case slipped a bit on the main hole sad

On the right hand side is a teeny tiny dip switch that goes between in and out sync.

I tried out this mod in my latest DMG, and it works pretty well. I needed to send the modular clock into an envelope first to get it to trigger the Game Boy which was a bit odd, but it syncs, so no big deal.

I did try to do the mod without a switch, but couldn't get it to work. Clock Out works when both in/out are wired up at the same time, but not In. As if LSDJ is getting confused with the pulses. I don't see why it shouldn't work though, so maybe worth someone with more electronics knowledge than me to have a bash. In the end I went with a teeny tiny DIP-style switch that is recessed in the case just above the sync jack.

In the future I might investigate putting the sync jack in the top right so that the cable won't get in the way of my right hand as much.

Thats cool! If you do open up that box please take a picture of the inside!

Tried to get it open today to take a shot, but it was screwed in so tight I couldn't manage it.

Thinking about it though, it would be pretty simple to wire up. You'd just need separate jacks for clock input and output... and they obviously couldn't be used at the same time. Could always just have a single jack with a switch too.

Well, I'm not sure how he did it, but the box works box for sync out and sync in... without a switch. Tempted to open it up and check out the wiring.

I put together a simple patch to show the DMG being clocked from my modular:
