Location of 2d match ball engine

hi how do you open the matchviewer
to change the ball on fm18

With the resource archiver

hi m8
whats that

In steam. Go to Library>>>>>Tools, and look for Football Manager 2018 Resource Archiver.

It lets you unpack the FMF files that SI use to archive much of their graphics with.

The archiver will let you select FMF files and unpack them to wherever you want. Then you should be able to make the changes you want and repack the files into an FMF file.
