Flash Movies found in Sonic Heroes files

[JetTheFox96]

Recently I was digging through the Sonic Heroes files. When I found a collection of Flash Movies inside the "files" folder for some reason. Here's a quick example



For some reason I thought these were supposed to be unused 2d cutscenes. When I opened it up I found nothing.



Someone please tell me what the what is going on, when did SEGA hear about Flash?
