Bit 0 : $28
Bit 1 : $48
Endianess : MSbF

Sync  : Bit 1

Then...

8 bytes: Identifier, read backwards. 3 of them have been found:

B2 B4 B2 D4 CE CF D2 C6 ("FRONT242" - Uppercase and reversed) in "Final Blow", "Rod Land (Side1)" 
85 8C 8C 85 88 83 89 8D ("MICHELLE" - Lowercase and reversed) in "S.W.I.V. (Side1)" 
C8 C3 D4 C9 D2 C4 CC C5 ("ELDRITCH" - Uppercase and reversed) in "Rod Land (Side2)", "Double Dragon 3", "Indy Heat" 

1 byte  : File ID
2 bytes : End address (MSBF)
2 bytes : Load address (MSBF)
n bytes : Data
1 byte  : Checksum

Its value is calculated by XORing Data bytes and adding 1 to the XOR checksum AFTER a byte 
is stored at an address with low byte being #$FF (eg. $08FF, $7DFF, etc.).


Trailer: Bit 0's.
