Can you go into the phrase screens for that LSDJ ROM or is it mainly for just playback?
You can only browse the song screen because some of the artists didn't want people to see their song. Effectively, select is disabled and A has a different function. So yeah, playback. The data is stored in ROM and not RAM.
Um, hello. (*cough*) Sorry for delaying the release. Totally my fault. Software development takes time sometimes. Buy the DVD so you get that ROM.

i installed this using wine. but theres a comm port error, tried all of them and no bueno
hmmm. its funny because it looks SOOO familiar to jose's hahaha
Yep, no shit... In his latest version he fakes the firmware version so it looks like the cartridge/programmer has firmware v 3.0, when in fact no such thing exists.
Anyway, you need the FTDI driver, which you can get here:

The DC power socket contains a little switch which turns bypasses the batteries when the plug is connected. If you shorted the DC plug to the batteries, the batteries would leak or explode. This switch is probably stuck or corroded internally. You could try to wiggle it a little to see if that helps. You could also bypass this switch entirely, but then you would have to make absolutely sure that you don't connect batteries and the DC jack at the same time, even when the Gameboy isn't turned on.
Just a very quick status update. I realized with this chip that it doesn't actually contain an internal quartz crystal, only the capability to use an external crystal without additional circuitry. So you either need a crystal, or drive it from the Gameboy's clock. This should work fine and this is just an aside.
I finally sat down with this the other night, and it failed completely. I still have some ideas for what the problem is, from scope output just before I left the lab. (In particular the behavior of the Gameboy's /CS line as well as a peculiar behavior where the FM chip outputs data to the data bus, while other wise being read only.) I still believe I should be able to get this working with a few changes to my ugly air wire circuit.
Then there's the issue of whether to route the audio through the input, or mix it directly with the "prosund" after the CPU. The FM chip has two outputs, one for tone audio and one for drum audio. One possible configuration is drums as mono, mixed after the CPU, and the tone output connected to the audio input of the CPU, which would allow for panning of it. And I will have to investigate which voltage levels the input can accept.
So, nothing too exciting yet, just a quick status update.
You mean this one?
You can see how some of the lines to down on to the green flat flex board, and those are the signal lines. If you've only damaged the ones on the side, which is a test pattern, you should be fine. In this image, I've obviously damaged more than those.
You can get pretty filter-sweepy sounds out of any 2-op synth with feedback modulation, or at least a patch that goes from no harmonics to a lot over the TL range. Here's a sample of my own 2-op FM 303 emulator thing: http://soundcloud.com/boomlinde/r-odent-dx303. I guess that with some imagination, those sweeps could as well have been filters.
That's nice and all, but it's not a filter sweep. You only have one overtone at your disposal at a time, which you can change the amount of influence of.
Nah. That guy is just trolling us. He was always called Stern Fucking Zeit.
I get +50 points for owning two OPL laptops and -100 points for not understanding ADt2 well enough to actually use it effectively. 
I'm sounding like a preacher, but may I suggest that you use BGB for recording the videos, to get slightly better audio quality. VBA has clearly audible artifacts.
Use BGB and use the built-in wave export function.

They are? Source?
If they are, it would be through Virtual Console on either Wii or DSi/3DS.
They may as well ban computers!
That's kind of where the trend is going, with walled garden devices like the iDevices and Microsoft's restrictions for Windows ARM devices.
Sorry. I only saw Chainsaw Police's post. I see the IP in the ping output.
Nitro, your manager loads faster than standard one lol. I always just launch song through little fm, so much faster
Of course. That's the power of spaghetti code written in assembly language. The downside is that even I find it hard to read the code one year after I wrote it.
