Extract the USB BootHID software i linked above.
Press the white button on the chip , you'll feel the click , then put it in the USB slot. Both the leds will light up. Give it a few seconds for the drivers to install << this is another reason why we went for ATMEGA as ATMEL requires signed drivers which are pita to install >>
Ok now that both the leds are on , launch the software.
Click Find Device. It'll do so. on the right side, click the find hex button. Here you will open the hex i linked above.
Now click flash. Give it two seconds. Some text will run down in the box after which it will say Flashing Completed.
Thats it... remove the chip. Now you can go play your games ! Btw , this is still not Hermes v4b , i'm still working on it.
