This level of requires compiling a new ROM image using Retro68 and flashing back. It is risky—bricking is permanent unless you have a ROM emulator like the "Rominator II." uint32_t word = rom_ptr[i]; sum += word; :
If your chips still boot, dump them via SCSI. Use ROMDump to save the entire 1MB address range ($40800000 to $40900000). Concatenate the two chip reads into a single quadra800.bin file. Checksum verification: A healthy Quadra 800 ROM has a checksum of 0x4F2B at offset 0x1FE. Use a hex editor to confirm. uint32_t word = rom_ptr[i]
