Well, I told abrasive I had things working some time ago and so he added that note to the homepage. Now that I'm not ready to release it yet, I thought I'd rather say so here than bother him to change the page, since I was planning to have a release ready soon anyway.

To anyone who might be wondering, the version of LittleFM that is publicly available does not work with derp. It's all working, but I need to finish the script for patching an LSDj ROM before I feel comfortable releasing it.

if that's the case, why does it say here on derpcart.com that LittleFM is in fact supported?  is that remark actually false?  just wanted some clarification.

Wasn't my message clear enough? I have it all working, but I haven't released that version of the software yet.

If it's the B button and left on the D pad that doesn't work, yeah you're pretty much screwed. This can happen when you insert or remove the the ribbon cable while the unit is on. The reason is that the combined input for the left and B buttons on the ribbon cable is situated next to the LCD power supply, which is nominally -19V. If you short that input to that power supply, (by slightly misaligning the ribbon cable at any point) you immediately fry it.
Edit: Repeating what I was quoted saying, using different words. Fun fun.

Oh sorry. Yeah, that didn't work out. I missed that error when trying the command. (The first one. The last two errors are harmless in this case.)

Try using sox, which is a utility for converting audio files.

sox in.wav -b 4 -c 1 --rate 11468 out.raw

-b 4 = 4 bit
-c 1 = mono
--rate 11468 = the sample rate. This depends on your wave playback driver. The value 11468 is correct for LSDj.

Hmm, off-topic? I prefer the term tangential, and I'm also somewhat serious. I really do mean that it might be a good strategy for Sabrepulse to send a friendly letter that starts with "how are you" and ends with "cease and desist".

Well if you know his Soundcloud, have you tried sending him a message?

Why not cut out the middleman and send it directly to me?

With a 74hc04, no. You need a DPDT switch for that. You could use a 74hc86 chip with a SPST chip. Described here:

Ok then. I always thought that the sound differences between DMG and MGB are caused by amps and other stuff and not by CPU. Guess there is no actual data on this anyway...

There is some data. For example, Herbert Weixelbaum's sound comparison.
http://www.herbertweixelbaum.com/comparison.htm

There's also an interesting (though not 100% confirmed) theory about the DACs of Gameboys described in the GBSOUND document.

PARTIALLY VERIFIED:On older versions (pre-DMG-CPU-05?) of the DMG, the scale

of

the DAC used on the various channels is semi-logarithmic instead of truly

linear. Later Gameboy models (MGB,SGB,CGB,GBA) used either better pull-up

resistor/capacitor and/or analog output DACs, and are almost perfectly

linear.

(Thanks Jeff Frohwein)

Here are some scales for demonstration:



TRUE Logarithmic:

0---------------1--------------2-------------3------------4-----------5----------6---------7--------8-------9------A-----B----C---D--E-F



TRUE Linear:

0--------1--------2--------3--------4--------5--------6--------7--------8--------9--------A--------B--------C--------D--------E--------F



Semi-Logarithmic:

0-----------1-----------2-----------3----------4---------5---------6---------7--------8-------9-------A-------B------C-----D-----E-----F

It's the same CPU architecture from the software's point of view. GBC obviously has extended functionality while the functionality is same in DMG and MGB CPUs. But the CPUs are quite possibly made with different manufacturing processes, which could influence the sound. There are of course also other differences in the design apart from the actual CPU chip. This includes the voltage regulator and the audio amplifier (assuming you're not using a prosounded unit) and just the fact that the MGB and GBC are using two AA/AAA batteries instead of four.

Have you tried cleaning the contacts? Internetz says that baking soda will get rid of the corrosion.

I went directly to Stickerbrush Symphony, and... it sounds nothing like the original.
