Hi, thanks for the comment. There are 2 main folders, so the English and Portuguese Version are each one on their folder. The duplicated files are for 2 kinds of keyboard control methods as described on the readme.txt. One control with the more traditional QAOPM, and other file have my personal control configuration QAOPW. Chose the .tap file with the keyboard configuration that you like most. The ohter are Mp3 files with the audio narrative. I hope to have helped you.
