STK500V2 wrapper corrupted (No Start Message detected!)!

[JacobDevine]

While trying to flash using the internal Amiibombuino Flasher, I tried flashing my Arduino Mega 2560 but it keeps coming up with the error: STK500V2 wrapper corrupted (No Start Message detected!)!
If anyone knows of a fix for this problem I would greatly appreciate it.

Edit: Now when trying to flash I get the error: Difference encountered during verification, write failed!
This error only comes up the first time I try flashing, then the previous error occurs, if I restart the program the error changes back again.

The "internal Amiibombuino Flasher" is actually an older copy of some of the files of my library over here (https://github.com/christophediericx/ArduinoSketchUploader). These files files were directly included in this project without proper attribution (as required per the MIT license).

This older version very likely has multiple issues with ATMega2560 that have since then been resolved in the base library. Either updating the relevant sources (and adding attribution) or consuming the nuget package (https://www.nuget.org/packages/ArduinoUploader/) would likely solve the issue.

Like the creator of the library said, I have to update the code inside AmiiBomb.
But you can use an external falsher with the .hex files provided as a temporary solution.
