converting mp3s to wavs

i don't get that. why do you have to convert your mp3s to wav. i mean neogeocd you don't have to do that, it just works when you type in the cue sheet track01.mp3 MP3. sorta wierd. i think this is saturn related.
heh n/m looked at the site said cdrwin automaticly changed mp3s to wav format
Yeah I used to convert the MP3s to WAVES when I was just starting out, but then I realized I can make a Cue sheet and burn with CDRWin without that extra step. Has it ever saved me a lot of time.
