DS Misc > slot2 am/fm radio

I've seen a couple of FM adapters for the DS, but they essentially just use the DS as a battery (have their own lcd, headphone jack, volume control, etc etc)

i'm curious if anyone knows what the big impediment is to building a cart that does radio reception, then relays it thru the DS?

i haven't seen such a device, but i imagine it allows you to normally play your games on the console. a device that would use the nds's audio hardware would take it from any game and thus no games could be played when listening to radio.

Three words: Ten bit DAC. That's why even Play-Yan has its own headphone jack. It's even worse if your cart starts in GBA mode, as that typically uses 8-bit sound.

erm, am and even fm radio would sound fine through a 10bit DAC... we do listen to mp3s and watch movies via Moonshell afterall... no one seems to complain about the sound quality with those formats.

Radio isn't exactly high fidelity audio in the first place. Most of the stations I have heard, even FM, sound like garbage. I have listened to streaming audio at better quality.
