ROM-Dump

Scripts and code for ROM dump.

Bash commands used

Breaks binary into smaller, viewable image files, with headers

for n in $(seq 0 10); do dd if=../legend.bin skip=$(($n * 80000)) bs=1 count=80000 of=$n.bin; echo "P4 8 10000 " > $n.pgm; cat $n.bin >> $n.pgm; done

Copies first 2**19 bytes; the size of the ROM because there are 19 address bits; copies without filesystem /usr/share/file/magic

dd if=rom.bin of=rom_low_clean.bin bs=1 count=$((2**19))

Rename using curlies

mv full_dump_d0_d5_{falling,rising}_edge.txt

Misc.

hexdump rom_full.bin            # see all hex values
xxd -c 32 rom_full.bin
radiff2 -c rom_full.bin rom_official.bin
binwalk -E rom_full.bin         # to find where interesting data might be
strings rom_full.bin            # find strings
