Do any of you know how upgrading of the firmware works? I know that you need some kind of JTAG USB Blaster but is it just plug and play? Or do you need to install something unto the NESRGB board before blasting away?
I had to upgrade mine (though it was in the last batch). You can upgrade it before you install the NESRGB or while it's in the NES (I did mine before install since I knew about it beforehand). You just connect the JTAG USB Blaster to the board, open a program on your computer, then run the upgrade. The board already has a row of holes ready to accommodate the Blaster, easy as pie.
On that note, if anyone in New Zealand ever needs theirs blasting, I am happy to do it for you. Just sayin'...
