'''Decapping''' (decapsulation) or delidding of an integrated circuit is the process of removing the protective cover of a microchip so that the contained die is revealed for visual inspection of the micro circuitry imprinted on the die. This process is sometimes necessary in emulation projects to copy information from [[Wikipedia:Digital_rights_management|DRM-protected]] ROM chips. Particularly [[MAME]] and other [[Arcade emulators|arcade emulators]] benefit from decapping projects.
