 This tool has been tested & confirmed to work on the following SF2000 firmware/SD card image versions:
 * Launch version (with English & Chinese languages only)
 * 2023-04-20 update (with 17 languages)
+* 2023-05-12 update (adds keymapping, favourites, history) - This works but can mess up the favourites and history
+  sections as they're based on position in the list rather than filename. For the time being, if you have problems,
+  delete Resources/Favorites.bin and Resources/History.bin from the SD card. This won't stop the features from working
+  but will remove any existing favourites or history you have.
+
 
 Use on any later versions is at your own risk!
