Documentation for cycle accurate Game Boy CPU
Gekkio's GB-CTR is a good reference of the SM83 (Gameboy CPU) with access pattern withM cycle accuracy. The GB-research repo by the same author also contains a lot of information.

Best documentation for the details?
The thing about the Game Boy (or most consoles, really, but especially the Game Boy since it uses a custom CPU) is that we don't know all the details. People have had to reverse engineer it to figure stuff out. /u/gekkio is one of the people doing that work, and his technical reference and test suite are the (ongoing) results of that.

Gameboy Doctor: debug and fix your gameboy emulator
Hey there! I've been working on a Game Boy emulator since last year and found the GameRoy project, which translated the PPU's logic from SameBoy, the (AFAIK) most accurate GB emulator around. I basically copied the PPU logic into my emulator and replaced the "state" property (an integer) with enums for some extra clarity.

GameRoy: a cross platform and highly accurate Game Boy emulator
So, what I have finally tried was figure out the timing from another emulator, in this case SameBoy, which appears to be the most accurate game boy emulator. In the end, I copy the timing from its ppu state maching, and its interrupt handling code. Took a lot of time figuring out how it was working.
