ghidra-snes Features

ROM Loading

• Automatic SNES/SFC ROM header detection
• Supports rom mappings:
  • LoROM
  • HiROM
  • ExHiROM
  • SA-1
  • S-DD1
  • SPC7110
• Automatic copier (.smc) header detection
• Internal ROM metadata extraction:
  • Title
  • ROM size
  • RAM size
  • Mapping mode
  • Checksums
• ROM checksum verification
• Persistent cartridge metadata stored in Ghidra program options

Memory Mapping

• Canonical SNES ROM memory mapping (depending on mapping type)
• Canonical SNES RAM memory mapping ($7E:0000-$7F-FFFF)
• Canonical System Area mapping ($00:0000-$5FFF)
• First-bank ROM mirrors ($00:8000-$FFFF) correctly expose internal ROM headers
• MMIO register blocks and labels
• Separate ROM/System memory views

Language Support

• 65C816-compatible loading workflow
• Automatic reset vector discovery
• Interrupt vector exposure
• Named MMIO labels
• Ghidra-compatible memory block layout

Testing

• Unit-tested ROM mapping logic
• Unit-tested checksum logic
• Functional tests against real commercial ROM dumps
• Ghidra test harness integration tests

Current Limitations

• Enhancement chips are currently treated as memory-layout variants, not full hardware implementations
• S-DD1 and SPC7110 mappings are intended for static analysis, not emulation accuracy
• Some enhancement-chip mirror behavior may still differ from emulator implementations
