Dumping the Gameboy Color boot ROM (w/ commented disassembly)
- jey 17y agoDecapping, staining, and reading ROMs with a microscope?? Using some clock timing trick to electrically dump ROMs? Holy crap that is some insane dedication.

- sp332 17y agoThe Mifare Classic hackers cut slices off the chip, scanned the slices and used a buggy Matlab script to recreate the circuitry inside. http://news.ycombinator.com/item?id=825150 http://news.ycombinator.com/item?id=825150
- tjic 17y agoThis is quite interesting, but being a CS guy who just took a few hardware courses 15 years ago, there's something I'm missing here. I thought that if you took a ROM and just fed addresses and a clock signal into it, you'd get the data on the data out lines. Clearly there's something trickier going on here. Can anyone explain? Thanks!
- wmf 17y agoI think the ROM in question is not a separate chip but buried inside the processor.
- joshuaxls 17y agoReminds me of the incredibly creative hack where one of the iPodLinux developers dumped the iPod's bootloader by sounding out ticks on its crappy piezo.
