We are looking for songs that are newly composed for this compilation. We are asking for a portfolio or similar to be able judge your composition style. The reason being, since this is paid work, we prefer to discuss the details before the artists starts working on a song, to avoid a situation where the artist works for many hours on something that we ultimately can't accept. As Apeshit mentioned in the original post, you're still welcome to submit a song for the compilation without this step, but with the risk that it's not accepted for the compilation.

It has a link port on the front so anything that works on a regular GBA should probably work on the Player as well.

This is a forum for people making music using old computers and video game consoles. You probably won't find any advice regarding supercomputer chips here. Maybe try the EEVBlog forum.


The talking C is mostly me. The password is shared between all the admins, but in fact I believe only me and Tim have access to it now since we changed it after it got hacked. Nothing bad was tweeted or anything like that, but the account was suddenly used for following thousands of people. So that's some insight from the other side into how "buying Twitter followers" works.

Yeah, the tweet was mostly about the pun: dog, woof. I considered saying just woofer instead of subwoofer, to make the pun even clearer, but didn't. I often wonder if the puns (when the lines are puns) are too dry.

New version released.

New in BGB 1.5.3 (2017-03-04) - Accuracy improvements, including: pokemon (all versions) now has correct TID for speedruns. Fixed a large number of bugs and problems, including: "uncoverable direct3d error" on some Optimus laptops. Added improved support for automation/commandline use. Significant performance/efficiency improvement with most roms. Added support for loading RTC .sav files where a timestamp in the future does not (incorrectly) advance time.

This is an interesting idea.. if you use something super reflective (ie. moreso than the film from a stock gameboy) would it mean you could see your reflection in it?!

You already can, even if faintly. If you hold your finger to a stock DMG screen and look closely, you'll see two reflections, just like on a regular mirror btw. One from the front of the glass, and a fainter one that is slightly offset, from the reflective layer. For best effect use a spotlight pointing to the area you;re looking at.

You've done your research. Well done. Indeed, left and B share the same physical input on the CPU. If you insert or remove the ribbon cable while the DMG is on, and misalign the cable ever so slightly so this connection is short circuited to the next one, which happens to be a -19 V supply for the LCD, the left/B input on the CPU is permanently damaged. Moral of the story, always turn off the DMG before inserting/removing that connector.

Are you absolutely sure the B button still works? There's really no way the left button could be broken without the b button unless there was some kind of problem, like a broken trace, around the area before the the B and left traces meet up on the LCD board. But then it wouldn't make sense that the button would start working, unless you accidentally rejiggered something in the process. If indeed it's an intermittent problem with the LCD board button connections, the good news is that you should be able to fix it with a little bit of soldering.

If it turns out to be a CPU problem, don't throw it away. You could give this 'boy some new life as a LSDj slave mode player, or MIDI synth.

As for probing, these are the relevant signals on the ribbon cable:

Pin 04 Left & B buttons
Pin 05 Button Diodes 1 & 2 (directionals)
Pin 06 Down & Start buttons
Pin 07 Up & Select buttons
Pin 08 Right & A Buttons
Pin 09 Button Diodes 3 & 4 (buttons)

The way it works is you have to put the negative (black) multimeter probe on the "diode" connection and the positive (red) probe on the other corresponding connection. As you press a button those two connections will short. Since there is a diode in series, you need to use the diode mode rather than the resistance mode, and beeping may not work so you might have to look at the multimeter screen for a readout instead.

Schematic for reference:

Site5, but currently planning to move the site because of this discussion.

jeff: Currently, chipmusic.org runs on a Site5 account. There's ssh access but I believe it's managed hosting, so no access to root or global server config. According to their FAQs, LE is not supported at this time. If you have information on how to get LE working on Site5 in particular I'd be willing to listen. But otherwise, switching to a different provider is unfortunately something that neither me nor Tim has the time to do atm.

Have you checked that you didn't swap ground and signal for either of the outputs? I probably would have used blue wire for both the grounds and red wire for both the signals to avoid this mistake.
You're tapping SID 1's output directly from the chip. Do you have any kind of circuitry between it and the output jack? You should ideally have a transistor circuitry like the one on the board, or just reuse the one on the C64 motherboard. Or at the very least a 1k resistor and 10 uF capacitor (example values) in series to protect the chip and remove the DC offset from the signal.

Y'all are all wrong! The problem was that the links started with an upper-case H. This made the URL parser turn this

No colon was omitted on the part of the poster. This was done by the browser.

At the request of nordloef, I modded Carillon to include a waveform editor for ch3 in the ROM. To try it, download carillon-wf.zip from here. Bug reports and feature requests are accepted.

But do you have any reason to believe that other than the name?

You know what, changed my mind. The sexist stuff (and following discussion) is now moved to the graveyard and I gave Martin a two week ban.

No, probably not normal. Can you do what I suggested above with regard to that? Please check during the startup sequence that it cycles through every LED and that none are missing from the sequence. Then also press the mode button and see if that does anything.
