The music converter part of the app does convert mp3s to gbs, but the results are quite pathetic. You got to be hardup for noise if you are going to listen to the results. I hate to think of the result of converting a movie file.
The
default sound quality setting in the converter is 32:1 mono, and the results are disastrous. The sound quality is horrible that way.
Set the sound quality to 8:1 stereo, and the quality improves. Still, you have to use earphones, because the built-in speaker on the GBA SP is too weak, and generally sucks.
As for movies, the higher quality settings look OK, although the framerate is 10 fps, so you get glitches and choppyness in faster action scenes. It's okay for sitcoms.
But cartoons and anime look great on the GBA. I have tons of anime in GBM format, and the entire Invader Zim series, a lot of Dexter's lab, tons of other cartoons, and I'm quite satisfied with them.
Still, the quality and framerate of DPG video in DS mode is much better; no wonder, the DS is 6 times faster than the GBA
For more info on video on both GBA and DS (and also... um...
sample encodes, which are "in no way at all" full length movies and anime encoded into GBM (GBA video), and DPG (DS video)
), visit
