I'm trying to understand the files in a Virtual Console wad file. The one I'm looking at right now has 5 different extensions. I can figure out the other four but there are a bunch of .app files starting from 00000000.app to 00000008.app and I have absolutely no idea what their format is. I heard they contain resources for the game and all the .app files are not one single format, but different formats and only the extensions are the same and the number in the file name identifies the purpose of the file. I searched for info about these .app files but "app" is a very common abbreviation for 'application' so googling gives so may irrelevant results. I just thought someone here already knows about this stuff and could give me a little advice. Links to info about app files or even posts on a forum would be very helpful. Thanks.
