Pro-mod would be cool but if there's something wrong with the cart itself, would that necessarily fix it? It could go either way. I'd be fine with a normal SGB (also just using it for messing around or when batteries die, etc.) if the volume output wasn't so brutally low on the one I got. Haven't had time to try cleaning it.. maybe this weekend.

Link port mod for model 1:

I find SGB good for composing when batteries are dead, or for demonstration purposes.
I've yet to hear anyone performing with one though, I would if I could find two of the 2nd model ones with link ports.

low-gain made a promod out of this shit. its supposed to be good.

Hm. I guess I should try to open it up and clean it and look for anything else fishy in there. I feel like this seller deserves negative feedback >:(

could be dodgy contacts, or the caps have blown in the super gameboy, never heard of that happening but its possible

I just received a Super Game Boy that I won in an eBay auction and decided to test it out for the first time. I'm finding that the audio output when running a GB cart is really, really, ridiculously soft. The start-up sound is certainly loud enough, and normal SNES games are working fine with regular levels.. I thought maybe it might be an LSDJ thing, but even a normal GB cart (Super Mario Land 2) is practically inaudible unless I turn the TV up like four times as loud as I normally have to set it. I guess I'm wondering a) if this is normal (doesn't seem likely) and b) if anyone else has experienced this and might know why it's happening or have a fix (besides a pro-sound mod). I guess this is what you get when you win an SGB for $6 :-/ Though it was described as working well...

Thanks!
