Just an idea, maybe you can load the ROM in VBA (preferably VBA-m) on the computer and choose file/load to load a save state. Hopefully, the format is the same. If that works, the VBA in your computer should spit out a sav file.

Yea but the wav channel only has four bits of resolution, so you cant really escape that?

The wave channel and master volumes work in different ways. The wave channel volume lower the volume by shifting each sample and discarding the lower bits. So in effect, wave channel only has 3 and 2 bits of resolution for the lower volume settings. The master volume does not have THIS problem but obviously affects all sound channels routed to that stereo channel.

Look for any settings related to automatic gain control or audio enhancement in the control panel and disable them. These settings are often on by default which makes sense if you plug in a microphone and use it for something like Skype, but not so much for recording music.
You now have to be more careful about watching the input levels and decrease the recording volume to the point that the audio doesn't clip.

Look at the right side of the cartridge circuit board if you get a chance. wink

Utabi, though he actually composes on a x6800, I realize. Still Yamaha FM. More IDM-ish sound.

Find a better way to bring attention to your videos than a shocking, unrelated title.

Oh sorry, more nit(ro)picking. The rules state that you must specify prices for the things you are selling.

Oh. Open the Gameboy and take the contacts out so you can rinse them afterwards. Obviously that's more work if the problem is with the one of the contacts that are connected to the motherboard, but I've found that in most cases people have apparently stored 'boys in a position that makes the battery acid run down to the bottom contacts only.

There's only one way to find out, right?

Agent Shhh was both annoying and entertaining at times, but you can't come around the fact that he (the persona) was a troll.

If you have continuity between the pad and and via near the CPU, how could the trace between under the cartridge slot be broken?

You may want to use this btw:

It can be used to check the buttons if you want to experiment with things. It also plays notes (a different one for each button) so you don't have to have access to the screen to use it.

Time to be a little condescending but hopefully right, then!

I don't believe it is related to the corrosion issues because that seemed to be isolated to the other side of the board.

Incorrect assumption. It's not actually just the area around the D pad that matters. If the connection is severed at any point on the way, the button will not work. The copper pad under the down button has two connections. The right one pad goes to ground whereas the left pad has a trace that goes up to the CPU. The right pad should have a solid connection, and is probably not where the problem lies.The left pad has a trace that goes up and changes side a couple of times. Here are two images where I've traced out the path of this trace. Note that the trace is covered by the cartridge slot on the front side.

Front:


Try testing for continuity using a multimeter between the left copper (actually probably gold plated) pad of the down button and the topmost spot on the same side. Ie, the via (as the connections between the sides are called) above the 03. You may to wiggle slightly with the probe to get contact.
If you find that this connection is broken, do not solder a wire directly to the pad where the button goes, but instead to the test pad named P03 near the button pad. Do this using as thin wires as you can get and route it all the way to a point along the indicated path which has a good connection the rest of the way to the CPU. Route it in such a way that the wire doesn't block any of the other buttons.

Good luck. (Hey wait, I'm supposed to be condescending.) Yeah, "good luck", I guess.
