002 - Cheap And Easy
Dmitry Grinberg, a hardware hacker and reverse engineer, discusses his journey from writing PalmOS utilities as a teenager to his recent projects involving the Sega Dreamcast VMU and Cypress PSoC 4 microcontrollers. He details the technical challenges of reverse engineering the VMU's Maple bus protocol, creating an IDA Pro plugin for its custom Sanyo 68K CPU, and writing an ARM emulator to run C code on the device. Grinberg also explains how he exploited the PSoC 4's supervisory ROM to dump its firmware and uncripple lower-end chips by removing market segmentation restrictions.
