Pros: Faithfully done. Honestly I'm hard pressed to tell a difference between this and the GBA rendition. Impressed.
Con: Mm, not much here. I can image redoing a 'modern' song on 16 bits is challenging enough without being perfect, but can't come up with much for cons.
Other: I liked it. It's not as 'fast' as I seem to remember on the original, but everything else seems spot on.
Please contact me if you would like to use this in a project. We can discuss the details.
