How to open a SMC file?

The most common reason why a SMC file cannot be opened is the absence of required software. To fix this, select a compatible program from the list. Then visit the official developer website via the provided link, download the program, and install it on your system.

The most popular programs for working with SMC files are ZSNES, Snes9x and OpenEmu. To get the latest version of ZSNES, open the ZSNES website where a universal installer for all operating systems is available.

Once setup is done, your operating system should assign ZSNES as the default app for SMC files.

What are the signs that my SMC file is damaged?
