Nice pictures but there are a few corrections you'd need to make. Well, a lot.
The lockout chip is wrong, it's the one right between PPU and the AV out. The board marking CIC next to the chip IDs the lockout chip. The chip you have marked as the lockout is actually a 7404 (or variants) and they are basically hex inverters. You might want to add that the 2 large chips between the cart connector and the CPU/PPU are the SRAM chips. Both are 2K each.
You might want to note the main board is rev 11 (the number is next to PPU as "NES-CPU-xx" where xx is the rev number) Rev 11 has problem with 3rd party unlicensed games and unlicensed famicom adapter, they won't work at all. It was Nintendo's attempt to block them. A simple fix is to snip pin 4 of the lockout chip. From the picture, pin 4 is on the bottom of the CIC chip, 4th pin from the left.
Rush n Attack cart should be CHR ROM and not SRAM chip and the other large chip is the PRG ROM. CHR ROM contains the graphic and interfaces directly with the PPU (few NES cart don't have this) while PRG ROM contains the main program.
The 2 little chips on the top are mapper chips using off the shelf logic gate chips. This were common before Nintendo developed MMC chips.
You have the Zelda all right.
Renegade doesn't have CHRRAM but rather CHRROM.
