Functions

func Filename

func Filename(filetype string, cartName string) string

Filename creates a filename that (assuming a functioning clock) should not collide with any existing file. Note that the function does not test for this.

Format of returned string is:

filetype_cartname_YYYYMMDD_HHMMSS

Where cartname is the string returned by cartload.ShortName(). If there is no cartridge name the returned string will be of the format:

filetype_YYYYMMDD_HHMMSS

The filetype argument is simply another way of identifying the file uniquely. For example, if saving a screenshot the filetype might simply be "screenshot" or "photo".
