Once you have the Altera Blaster on hand, you will likely need to install the Altera Blaster driver by following the directions below:
In order to update the firmware on the NESRGB board, the board itself must already be installed in the Nintendo. This is because the board needs to be powered by the Nintendo during firmware updating procedures. When I updated mine, I removed the housing, shroud, and cartridge interface from the Nintendo, and then lifted the main board from the bottom housing so I could flip it over and move the bottom shroud to the side. This gave me direct access to the NESRGB board while still being able to plug the power cord into the Nintendo.
So here comes the tricky part: You'll need to strip the ribbon cable that came with your Altera Blaster down to six individual wires. The red coating on the first wire corresponds to pin #1 on the Altera Blaster, and each wire after that corresponds to the next pin (i.e. the 2nd wire goes to pin #2, the 3rd wire goes to pin #3, and so on). The wires you want are 1, 2, 3, 4, 5, and 9. These will be hooked into the 6 terminal holes on the NESRGB board as indicated below:
Wire #4 goes into the "3V3" terminal.
Wire #2 goes into the "GND" terminal.
Wire #3 goes into the "TDO" terminal.
Wire #1 goes into the "TCK" terminal.
Wire #9 goes into the "TDI" terminal.
Wire #5 goes into the "TMS" terminal.
Make absolutely certain you have the correct wires hooked into the correct terminals. I leave it to you to decide if you want to solder them or make a temporary interface (which is how I handled it). For reference, below is the Blaster pinout diagram:
Once you have everything hooked up, power on the Nintendo and plug the USB cord-side of the Altera Blaster into your PC. Then run the Quartus II 13.1 Programmer and follow the steps below:
If everything was done properly, you should see the progress bar fill with green as the programmer updates the NESRGB board. Wait until it finishes, then close the program (don't bother saving when prompted), turn the Nintendo's power off, and unhook the Altera from your PC and Nintendo.
