+If the game hangs after Sega logo, you may need to enable "better sync"
+and/or "Scale/Rot. fx" options, found in "Sega/Mega CD options" submenu, and

+If FMV game performance is poor, try adjusting "ReadAhead buffer" to something

 * PicoDrive is not a mp3 player, so all mp3s MUST be encoded at 44.1kHz stereo.
-  Otherwise mp3s will play too fast or too slow.
+  Badly encoded mp3s can cause various kind of problems, like noises, incorrect

+* Use lower bitrate for better performance (96 or 128kbps CBRs recommended).
 * Due to internal implementation mp3s must not be larger that ~15MB
   (15548416 bytes). Larger mp3s will not be fully loaded.

 * RAM timings option is good for dualcore operation (it is disabled by
   default because it doesn't work on every GP2X, so enable it in advanced
