Final Burn Alpha has had TAS features for a long time already as indicated by this thread, but it is not yet accepted on this site.
Fans of this emulator have kept a very low profile, so it hasn't really progressed either.
Thanks to inspiration from AngerFist, I checked out quick what's the status of the FR file format.
It seems to contain everything necessary, except the indication whether the game begins from reset or not. There
is a "number of frames played before starting the movie" field, but it is undocumented whether this field can actually be trusted. If the field is hex-edited to zero, does the emulator reset the console when it loads the movie, or not?
Also, how portable is this emulator? How does it compare to the items at
http://tasvideos.org/NewEmulatorConditions.html ?
It is long overdue to start accepting movies for this emulator, but these issues should be cleared first.
