Oh, great!!!, this app! Finally I can hear the sound tracks of my SNES games on my mac. (I recommend the DKC tracks to you, very good.)
I read that Audio Overload v2.0 will come soon... ;D
Here's a little preview by the developer:
"As it stands right now, AO2 supports nine formats - .ay, .gbs, .gym, .hes, .kss, .nsf, .sndh, .spc, and .vgm. As with the original Audio Overload, .rar files are supported transparently. Unlike the original Audio Overload, however, the new version has been designed to be portable. The unique but totally non-standard interface that AO1 featured has been abandoned. AO2 will use platform native widgets on each of the supported platforms."
