POD File Format Derivates

All information here is to my best knowledge, is is not proven by any official reference manual by Terminal Reality.

POD file format CRC-32/MPEG-2 checksum variant

poly    : 0x04C11DB7
ref_in  : false
ref_out : false
xor_in  : 0xFFFFFFFF
xor_out : 0

POD file format variants different checksum ranges

POD2 : offset=sizeof(ident)+sizeof(checksum) count=sizeof(file  )-offset
POD3 : offset=sizeof(ident)+sizeof(checksum) count=sizeof(header)-offset=280
POD4 : offset=sizeof(ident)+sizeof(checksum) count=sizeof(header)-offset
POD5 : offset=sizeof(ident)+sizeof(checksum) count=sizeof(header)-offset
EPD  : offset=sizeof(header)                 count=sizeof(file  )-offset
POD6 : offset=sizeof(header)                 count=sizeof(file  )-offset
POD1 : offset=sizeof(header)=4+80            count=sizeof(file  )-offset
