CAPS0ff writes: In a previous post we described some early attempts to analyze the Taito C-Chip. See Haze's forum post for some background on the C-Chip itself. In particular we're interested in the EPROM. Previous efforts focused on less invasive techniques with the goal of keeping the C-Chip alive after...

Once these chips are programmed, they can only be erased by shining ultraviolet light through the window. The EPROM help page is a guide to identifying and working with these devices. It also covers more...
