How reliable is the initial state of the NES? Is it possible to hash it into a seed for an RNG? inb4 2A03 noise channel

There are a few sources of randomness to work off of here, so yeah, it's possible. A simple "frames passed since powerup" seed would probably sufficient for a game, though, and would make your game much more playable across emulators that don't correctly emulate power up state.

Not reliable, but probably not terribly random.  I would bet that the work RAM, OAM RAM, and the CPU registers decay to mostly 1's in the absence of power.  So, if you write values to RAM, remove power for a second, and then turn it back on, various bits will randomly change to 1.  No way to tell which will be set to 1.
