Comment 1:
Software from e-Reader cards is stored in a proprietary vpk compression format within the save file. Trimming the save file down to just the vpk file and decompressing it using nvpktool gets you the ROM.

Comment 1:
As what may be a form of copy protection, NES-e series ROMs have bytes 0x3FFA, 0x3FFB, and sometimes 0x3FFD changed so that the ROM is unusable in emulators and flashcarts. These bytes are changed back to what they're supposed to be by the e-Reader's NES emulator by the time the ROM is loaded into memory.
