• Massive flash speed improvements
• Savefile support. Receive and send savefiles between your PC and the HyperBoy.
• Stability Fixes. A recent Windows update (most likely) caused some stability issues on the Windows application causing it to close when connecting to the HyperBoy. Should not happen anymore.
• Backwards compatibility. You can use a HyperBoy with an old firmware using the new application. It will still speed up flash speeds a bit but most new features need the update
