DSR RAM Handler format

The DSR ROM format is a headered ROM dump format from the memory chips from an expansion card of the PE-Box (i.e.), created by E.P. Rebel from Netherlands.

The contents of these files are taken from the DSR ROMs of en expansion card, so there must be meta-data about the origin of the data. In fact, these files are commonly 8198 bytes long, that is, 6 bytes for header information plus the common size of a ROM (8K).
