Notes about the CHD file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The CHD file type is primarily associated with 'MAME' by MAME Team.
MAME = Multiple Arcade Machine Emulator.
MAME allows people to enjoy long-lost arcade games and even some newer ones; the main purpose of the project is to document the hardware (and software) of the arcade games.
