When I plug my prosound into my line in, it is much louder and cleaner than the headphone port, and the bass has a lot more depth to it

Plug the prosound into a powered speaker unit.

kitsch is much more helpful than I.

It honestly didn't occur to me that he could be trying to use the prosound out with headphones.

it will be quieter, much quieter, depending on the type of headphones you're using.  the prosound mod bypasses the headphone amp inside the dmg (DMG-AMP i think is the name printed on it), so if your headphones need some sort of boost it won't be there for them.  try a basic set of earbuds.  the point of the mod isn't to increase the volume, or the bass, or whatever.  the fundamental point of the mod is to bypass the amp circuitry and ditch some of the noise for better audio quality.  in doing this, you also bypass the amp for the headphones, as the noise is coming in through this part of the circuitry.  the solder points for the prosound mod are almost directly off the CPU itself, so a cleaner signal.

the clipping issue sounds like it may be a wrong installation or you've got a loop, but it may also be a result of the particular type of DMG revision you have.  there is a thread somewhere on this site about this, but the result of it all was finding out the the "B" version of the DMG-CPU on the PCB version 2 has issues in playback, notably on the wav channel.  (someone needs to confirm this though, entirely from foggy memory).  so, when you've got your gameboy open, look at the CPU chip and see if its a B.  you can remove the battery cover and look through the latch hole, the PCB version will be printed there.  DMG-CPU-02 is what you're looking for.  an 02 with a B may be part of the problem.

Something is wrong with it, or you are using it incorrectly.

I never use my prosound out. It has clipping issues, and it's in fact quieter than the regular headphone out.

Backlights are the only useful mod IMO. everything else is just stupid and borderline useless.

for this one I don't think I'm going to paint the case, im just going to leave it as is

Lol, hey, doing mods are fun too. Don't hate!

Personally, the only things worth it are prosound and backlight. But if you want cool paint ideas I could come up with something for you.

:[

ya, but whats the fun in that?

you could... leave it stock and just use the damn thing.

think I should leave the case as white, leave the original screen covor and use blue buttons and a blue backlight?

Bivert/Backlight/Prosound

can't go wrong with this combo.

Yup.

Also should I have it inverted or not?
