Be sure NOT to use anything but classic mp3 format (don't use things like
mp3pro).
ISO files can also be zipped (but not mp3 files, as they are already
compressed). Note that this can cause very long loading times, which may
take up to several minutes. File naming is similar as with uncompressed ISOs.
ISO files can also be .cso compressed or zipped (but not mp3 files, as they
are already compressed). CSO will cause slightly longer loading times, and
is not very good for FMV games. Zipping ISOs is not recommened, as it will
cause very long (several minute) loading times, and make some games
unplayable. File naming is similar as with uncompressed ISOs.

PicoDrive is not a mp3 player, so all mp3s MUST be encoded at 44.1kHz stereo.
Badly encoded mp3s can cause various kind of problems, like noises, incorrect
playback speeds, not repeating music or even prevent game from starting.
Some games (like Snatcher) may hang in certain scenes because of this.
Some mp3 rippers/encoders remove silence and beginning/end of audio tracks,
what causes audio desyncs and/or mentioned problems.
* Sega/Mega CD: If your games hangs at the BIOS screen (with planets shown),
