The photos above show what the interior of SF's cartridge looks like. I will write more about this later, when I know more about it. Notice that the SuperFX is labeled as Mario Chip 1, which was its development name. Also there are no surface-mounted chip packages, as in other Nintendo, Game Boy, and SNES circuit boards I've seen. This may have been a cost saving measure due to the $10 price of the SuperFX, but it could also be for security: the plastic coating makes it difficult to peel apart the chip without destroying it, thus creating another setback for any reverse enginnering effort.

It's impossible to see in any of my photos, but if you hold the board in the right light, you can see outlines of the silicon chips in the plastic. In the last photo, I've drawn them in pink so you may compare the realitive sizes of the RAM, Mario Chip, ROM, and Nintendo's lockout chips (that's what CIC is). I've also written in some of the characters printed on the board, as these may also be difficult to see. Also, the copyright year on the top right is 1990; 1992 for the Mario Chip; and 1993 in between the ROM and the lockout chips.
