		As the title suggests i have stripped and scanned my sega saturn action replay and scanned in the motherboard at 1200 dpi so you can see and follow any of the traces for anyone who is interested in recreating or modding it. Front: Back: Board Measurements: Main Components: Notes: C3, C4, C5, C7, C8, C9, C10 and C11 all tested as 0.79uF i'm not sure what C1 is, there was no reading from it and no continuity. D1, D2, D3, D4 are 1N4148 fast switching diodes

		If you have the necessary equipment, it'd be cool if you could try extract the logic equations... from the PALs.
