There are so many mysteries regarding the PPU, I hope we can solve them all!

Would be interesting to see what's different between the G and H revisions.. maybe only die size? I guess some people who have VS arcade boards have found that certain games won't work with the 2A03H.

H-revision (including 2A03) should be depackaged and delayered soon also.
