I had read about this short movie on SNK Wiki quite a while ago, but only today remembered to actually have a search for the video online.
For those who may not have heard of this, it is basically a rundown of all the events in the Fatal Fury universe up to Garou: MOTW. It was part of the 15th Anniversary of Fatal Fury CD Package.
Although the actual videos are in Japanese with no subs, you can read the basic plot summary of it on SNK Wiki.
