OK. I have a .pak file. It doesent matter where its from but ill say it contains sound effects for a game. I tried to open it with PAKscape but no luck. I dont know what else to try. I would appreciate it if anyone could give me ideas on how to open it.
If it came with a game the packfile format can be anything the game designers felt like making it. Your only choice is breaking out the hex editor and try to figure it out. Look for filenames, offsets, etc.
