Definitions Of Music Data
----------------------------------
*NOTE* The Following Is Not From Me. This Is From A Translated Page. I Take No Credit For The Following Descriptions.
Original Source = http://klikechange.free.fr/Rockman2.htm
I Will Strip It Down To Make It Less Difficult To Understand.

$00 XX: Speed (the extent whose XX is large it becomes slow)

$02 XX: Timbre change (inserting $00, $40, $80, C0 in XX, please try)

$03 XX: Way volume change (only $FF you do not insert in the non darkness, note)

$04 YY XX XX: The address which is shown with XX XX (the $28000 is not forgotten) to jump, the YY time it does that, (in case of 00 it is unlimited)

$05 XX: It rises 1 sound each height of the key (concerning 1)

$06: Length of diacritic of one rear is designated as 1.5 times.

$07 XX XX: But attenuation... because address it is not chased, don't you think? it is good and the ‚í can (someone to be possible) as for other things with 1byte Y length of diacritic (60 2 times that 40) plus does XX in the key which with XX is decided with height $05 XX of sound presently while collecting is (the ‚§ ‚¡ diacritic data (rectangular group and triangular group) Y0 (40,60,80, A0, C0, E0) + XX (00 - 1F) concerning diacritic one. XX in case of the $00 it becomes the ‹x sign. When we assume that $4F is 16 diacritical markses of ƒh, the $50 becomes 16 diacritical markses of the ƒh #, 6F becomes 8 diacritical markses of ƒh. It is in the midst of collecting concerning noise and effective sound.
