From the developer:
There is a beautiful new driver module included with AF allowing you to easily flash the ATMEGA via its ISP interface.
What you have to do is select the ISP serial/parallel Flasher and select the dongle type in the config dialog. You can select dongles for the parallel or serial port interface. The rest of the game, flashing though, is as easy as you are already used.
You may want to check out more software, such as e+ Pro, LXH-JME2202P Hotkey driver or GraphicUSB, which might be similar to AsuroFlash.
