Heavy on retro nostalgia, but there are good hardcore hacking bits in the talk.<p>I found it interesting both Capcom and later Sega used custom security scheme that encrypted specific address ranges used for code, and how it was defeated. Very same method is used to this day* in Bluray drives, and is as "easy" to defeat.<p>* Micah Scott is working on reverse engineering USB bluray recorder firmware. She found encrypted procedures in firmware running on one of the processors inside the drive, and was able to decrypt it using similar trick(pushing own code after decryption, but before execution over jtag)<p><a href="http://vimeo.com/channels/coastermelt/111417458" rel="nofollow">http://vimeo.com/channels/coastermelt/111417458</a> talk about decrypting AACS DRM function starts at ~10:00 minutes.
