The ROM/RAM format is a headered ROM dump format from the cartridge memory chips, created by E.P. Rebel from Netherlands.
The contents of these files are taken from the ROMs of the cartridge or other locations within the CPU address space, 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).

Length
This word specifies the *total* size of data. Is is the sum of the header size (6 bytes) plus the length of data. If the file is larger, only the given length of data is used.
Address
Memory address in the CPU address space.
