-If a SWF was made with ActionScript 2 (or 1) and Flash version 8 (or older), it will say it can work with the Wii. If the 'game stage' is larger than 700x500 pixels, it will warn about possible overlapping/clipping on the Wii.
+On your terminal, run `python3 SWFChecker.py` to start. 
+Make sure that your SWF file is in the same folder as the checker.
