I downloaded the soundtrack of Bomberman Jetters, but all the songs are in DSP format. Is there a way to convert them to MP3?

That's the soundtrack for the anime.

Ah shit sorry then man, tried finding a DSP to MP3 converter for you but no luck. I suggest you find another download of it thats mp3 ? That would probably be the easiest solution.

You could run the game in Dolphin and record the audio but that's kinda messy and painfully long to do. :/

Haven't tried this, but this one says it's able to do so.

from: MP3, WMA, WAV, OGG, AVI, AIFF, AIF, AIFC, AU, SND, MP2, MPA, MP1, MPC, MP+, ADPCM, GSM, and DSP. It will convert to: MP3, (CBR or VBR), WMA 9, WAV, OGG, MP2, ADPCM, GSM 6.10, DSP and VOX.

I believe that's supported by VGMStream. If it is, you can open it in WinAmp, and then output them to WAVs via WinAmp WavOut plugin (whatever it's called). Then, simply convert them to mp3s.
