How it works:
You burn PSXAmp to a CD. Boot the PSX with the PSXAmp CD, when you see the
PSXAmp interface, remove the CD, and replace it with a CD containing MP3s
(They MUST all be in the ROOT DIRECTORY! If not, MP3Amp will not
recognize it, and no, we can't "just" implement a "browsing environment",
so don't ask). PSXAmp will detect the new CD, read their filenames, now
you select which file to play. After a short delay (no longer tham 10
seconds), PSXAmp will begin playing your MP3!
