Kevtris releases V.2 firmware for Hi-Def NES

There are about 40 consoles out there with V.1 firmware so this really only concerns them, every kit/console from now on will have V.2 firmware.
The update fixes problems with mmc5 games like castlevania 3, Everdrive N8, FDS, saving scanlines settings, adds 4x height in 1080p to fix scanlines, the diagnostic LED flashes differently, and a couple audio levels are preset lower.
