Hello there! Here's an extended version of the soundtrack to Castlevania: Portrait of Ruin for the Nintendo DS. Since the official release has each track loop only once, I picked up some rips that ran for over ten minutes and shortened them as needed. Most songs loop twice and fade out, except for jingles, prologue, and staff roll BGMs. Enjoy and let me know what you think, folks: I've been sitting on this one for far too long.

Thanks for sharing your amazing work !

New links added; redownloaded the official soundtrack release and spliced audio so each song would loop twice or as needed. Along with the in-game soundtrack ("Game Sound"), new version includes Disc 2 ("Original Sound") found in the OST. All extensions were made by yours truly, save for track 2-11, which was handled by Jessie because the original song was simply unworkable.
