By default, all software supports multiple file extensions. ZSNES supports at least 22 different file extensions. The basic files that ZSNES supports are .SFC. However, not all of the extensions listed on the list are always used to save the effects of work in ZSNES. Very often, files with such extensions are used as source data files used by ZSNES.
ZSNES can be used to convert file formats between the file extensions listed below. You can open a file with one of the file extensions below via ZSNES and try to save it in another file format, also supported by ZSNES.
