The translator translates an instruction output from the target program to an instruction executable by the emulation apparatus. The first memory map is located in a memory region for use by the target program and is write-protected based on operation environment of the emulation apparatus. The second memory map is write-protected based on at least one of the execution environment of the target program and content of the instruction from the target program. The rewriting unit rewrites a first write instruction output from the translator to a second write instruction to the second memory map when the first write instruction causes a write protection violation to the first memory map."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Write-protected storage medium, write-protected apparatus, and write-protected environment","description":"An emulation apparatus includes a translator, a first memory map, a second memory map, and a rewriting unit.
