Leftmost one might be a screen magnifier. The next one after that looks for all the world like an FM radio powered by the GBA. The small thing looks like a headphone adapter. And then a 3rd party link cable. The plastic blob in the middle of the cable is a multiplayer connector with a socket. Then there's a car charger, but you likely figured that one out already.

In case my opinion is wanted, this should be your setup for this: Gamecube+GBA player and capture that video stream with a capture card/USB device to your computer. Then perhaps record a stream of your fingers on the controller. But that leaves you with the issue of synching the video streams. Or, perhaps even better, contact Oliver and ask him if he can he provide you with a version of NL that shows the buttons that are currently pressed overlaid on the screen so you can show a pure video stream of NL.

I think that's a good time to stop this discussion.

There are other pics of him, like this one. Definitely him.

I once had a post about his chiptune theft adventures. I unpublished it after he seemed to honestly want to make his own music and be a part of the community, but now I'm considering whether that good will is lost and I should republish the post.

Nope. Those won't work with Transferers.

A headphone output is an unbalanced circuit. Using a T or a Π type attenuator would likely be way overkill for your application. The point of those topologies is to match the impedance of both the input and the output in order to avoid signal reflections, which is mostly a problem for high frequency transmission lines.

You should use an L type attenuator, that is a two resistor voltage divider, but you may be able to get away with just a series resistor. The downside of just putting a resistor in series is that the attenuation will vary with the impedance of the headphones, if you have multiple different pairs of headphones that you wish to use with the same soundcard. Just shooting from the hip, you should aim for a resistor value that is slightly lower than the headphone impedance. Lower value = less attenuation. This could be done externally without modifying the soundcard, if you get a siutable stereo plug, and jack that you can use for an adapter. Standard 1/4 W resistors should be sufficient for this task.

Another option is to modify the soundcard internally. There will probably be a headphone amplifier. If you can attenuate the signal before going into the amplifier, you could apply a constant attenuation regardless of the headphone impedance. I could probably help you with that, but then I would need something to go on, preferably pictures of the internals of the soundcard around that area of the board.

What exactly do you mean by .hex? Intel hex format? It also contains address data, which you would need to add as well.

See this thread, and especially my posts: http://chipmusic.org/forums/topic/14290 … us-or-not/

The bottom line is, it's likely an automated copyright request that matched your song based on the notes in it, which likely were similar enough in pitch and volume curve to look like the original song.

My personal beef with it is that it's nonfree software. That being said, I still use it on occasion.
But I would be behind it 100% if it were GPL'd or something.

If it was 100% GPL (as opposed to, say, parts being LGPL) you may need to share the source song file for your music, if the exported module contains playback code. Arguably, the whole module would then become a derivative work of the GPL'd playback code.

If you stop the video at just the right frame and look carefully, you can see the hidden text, which subtly hints that that gentleman is indeed Christopher Poole, also known as "moot". It's a conspiracy!

You're correct that this used to work differently. The reason for the change as far as I remember was so you could use the detune feature to detune agy combination of pu1, pu2 and wav against each other. Before this change, you couldn't detune pu1 an wav against each other. You can of course create another instrument where you set finetune to 0 and play on either pu1 or pu2 to get less detuning.

The detune happens in the Gameboy sound chip\s internal values, which means it's neither measured in cents nor Hz. The frequency, given a certain GB pitch value, is givne by the formula:

f = 131072/(2048-x)

As you go higher in pitch, there are fewer frequency steps, and the error compared to the desired note increases.

Here's a handy table:
http://www.devrs.com/gb/files/sndtab.html

Let\s look at a couple of notes to demonstrate this.
A-3, supposed to be 110 Hz. The closest GB value is value 854. f = 131072/(2048-854) = 109.78 Hz
The next value above it is 855, giving f = 131072/(2048-855) = 109.87 Hz (So actually, it turns out that the table is inaccurate, but that doesn't matter. This is not the note table LSDj is using as far as I'm aware. And I'm just interested in approximately how big a one step difference is in that general range.)
This means that for A-3, the slowest beat frequency you can get between two detuned notes is 109.87-109.78 = 0.09 Hz.

A-5, supposed to be 440 Hz. The closest GB value is value 1750. f = 131072/(2048-1750) = 439.84 Hz
The next value above it is 1751, giving f = 131072/(2048-1751) = 441.32 Hz
This means that for A-3, the slowest beat frequency you can get between two detuned notes is 109.87-109.78 = 1.48 Hz.

A-7, supposed to be 1760 Hz. The closest GB value is value 1750. f = 131072/(2048-1974) = 1771.24 Hz
The next value above it is 1975, giving f = 131072/(2048-1975) = 1795.51 Hz
This means that for A-3, the slowest beat frequency you can get between two detuned notes is 24.27 Hz.
