+Sega/Mega CD options \r
+--------------------\r
+\r
+1,2,3. "USA/EUR/JAP BIOS"\r
+These options just shows if your BIOS files were correctly detected be the\r
+emulator (it shows the filename it is using). If so, you can press Start to test\r
+your BIOS.\r
+\r
+4. "CD LEDs"\r
+The Sega/Mega CD unit had two blinking LEDs (red and green) on it. This option\r
+will display them on left-top corner of the screen.\r
+\r
+5. "CDDA audio (using mp3s)"\r
+This option enables CD audio playback.\r
+\r
+6. "PCM audio"\r
+This enables 8 channel PCM sound source. It is required for some games to run,\r
+because they monitor state of the audio chip.\r
+\r
+7. "ReadAhead buffer"\r
+This option is for dealing with slow SD card access in GP2X, which makes FMV\r
+games unplayable. It will allow emulator not to access SD card for longer periods\r
+of time, but it will take more time to fill the buffer.\r
+\r
+8. "Scale/Rot. fx"\r
+The Sega/Mega CD had scaling/rotation chip, which allows effects similar to\r
+"Mode 7" effects in SNES. Unfortunately emulating it is slow, and very few games\r
+used it, so it's better to disable this option.\r
+\r
+9. "Better sync"\r
+This option is similar to "Perfect synchro" in Gens. Some games require it to run,\r
+for example most (all?) Wolfteam games, and some other ones. Don't use it for\r
+games which don't need it, it will just slow them down.\r
