       srec_stewie - Stewie's binary file format


       If you have a URL for documentation of this format, please let me know.

       Any  resemblance  to  the Motorola S‐Record is superficial, and extends
       only to the data records.  The header records and  termination  records
       are  completely different.  None of the other Motorola S‐Records record
       type are available.

   The Records
       All records start with  an  ASCII  capital  S  character,  value  0x53,
       followed  by  a  type  specifier  byte.   All records consist of binary

   The Header Record
       Each file starts with a fixed four byte header record.

                             │0x53 │ 0x30 │ 0x30 │ 0x33 │
   The Data Records
       Each data record consists of 5 fields. These are the type field, length
       field,  address  field, data field, and the checksum.  The lines always
       start with a capital S character.

              │0x53 │ Type │ Record Length │ Address │ Data │ Checksum │
       Type    The type field is a one byte field that specifies  whether  the
               record  has  a  two‐byte  address  field  (0x31),  a three‐byte
               address field (0x32) or a four‐byte address field (0x33).   The
               address is big‐endian.

       Record Length
               The  record length field is a one byte field that specifies the
               number of bytes in the record following this byte.

       Address This is a 2‐, 3‐ or 4‐byte address  that  specifies  where  the
               data in the record is to be loaded into memory.

       Data    The  data  field  contains the executable code, memory‐loadable
               data or descriptive information to be transferred.

               The checksum is a one byte  field  that  represents  the  least
               significant  byte  of  the  one's  complement of the sum of the
               values represented by the bytes making up the record's  length,
               address, and data fields.

   The Termination Record
       Each file ends with a fixed two byte termination record.

                                    │0x53 │ 0x38 │
   Size Multiplier
       In general, binary data will expand in sized by approximately 1.2 times
       when represented with this format.


       Here is an  hex‐dump  example  file.   It  contains  the  data  “Hello,
       World[rq] to be loaded at address 0.
              0000: 53 30 30 33 53 31 10 00 00 48 65 6C 6C 6F 2C 20  S003S1...Hello,
              0010: 57 6F 72 6C 64 0A 9D 53 38                       World..S8
