SEUCK TAPE 

--------------------------------------------------------------------------------

Found on the "Shoot'em Up Construction Kit" tape. 

For formatting of games created with SEUCK see "Seuck game tape" elsewhere. 

--------------------------------------------------------------------------------

Endianess : LSbF
Threshold : $2E (368 clock cycles)
Short : $1B
Long : $3D 

Pilot byte : $E3
Sync byte : $D5


This format uses 4 types of file... 

- SEUCK LOADER 2
- SEUCK HEADER FILE
- SEUCK DATA FILE
- SEUCK TRIGGER FILE


The CBM files contain a loader that is set to load just ONE file to address $000A, the 
file contains LOADER 2 and is formatted as follows... 


--------------------------
SEUCK LOADER 2... 

Handles loading of SEUCK HEADER,DATA and TRIGGER files. 

Load address = $000A, File Size = 196 bytes. 

Pilot : $E3 (*10)
Sync  : $D5
196 bytes data
Checksum (0 XOR all data bytes)


--------------------------
SEUCK HEADER FILE... 

Load address = $0002, File Size = 2 bytes. 

Only 1 header file exists on the tape, it provides a single load address for all following 
DATA files to load from. 

Pilot : $E3 (*10)
Sync  : $D5
ID Byte : Anything but $CC or $AA, the value $BB is found on the SEUCK tape)
2 bytes : Load address (LSBF)


--------------------------
SEUCK DATA FILE... 

Pilot : $E3 (*10)
Sync  : $D5
ID Byte : $CC
1 byte  : Data length (n)
n bytes : Data
1 byte  : Checksum (0 XOR all data bytes).


--------------------------
SEUCK TRIGGER FILE...

Provides a single execution address that will run the program. for the SEUCK it is $0810. 

Pilot : $E3 (*10)
Sync  : $D5
ID Byte : $AA
2 bytes : Execution Address ($10,$08)
