Overclock the NES. Go ahead, do it.

Go ahead, get that extra 300kHz out of the system, we dares ya. SMB hit 4.0MHz with graphic glitches, but stayed alive aight; SMB3 hit 3.6, then maxed at 4.2MHz; Kirby's Adventure couldn't make it past 4.0MHz, but ran stably there.
We're hoping with some casemods and liquid cooling we can hit 6.0MHz, but hey, this ain't no Celeron here, these be delicate 80s electronics.
