-# Gameboy (Sharp LR35902)
-
-The Gameboy's CPU is a custom chip called the Sharp LR35902. The chip is very similar to the much more popular Intel 8080 and the Zilog Z80.
-
-100 tests are provided per opcode, which the exception of `0xCB` which has 25,600 tests. All tests assume a full 64KB of uniquely-mapped RAM is mapped to the processor; this deviates from the actual memory layout of a Gameboy.
-
-The tests assume a decode-execute-prefetch loop and so start at PC+1, with the final cycle being the prefetch of the next instruction. See [Gameboy CPU Internals](https://gist.github.com/SonoSooS/c0055300670d678b5ae8433e20bea595#fetch-and-stuff) for more info.
-
-`STOP`, `HALT`, `EI` and `DI` are currently omitted until I can devise a meaningful way to test their behaviour.

-Sample test:

-| Field | Description |
-| --------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
-| `name` | Provided for human consumption and has no formal meaning. |
-| `initial` | The initial state of the processor; `ram` contains a list of values to store in memory prior to execution, each one in the form `[address, value]`. |
-| `final` | The state of the processor and relevant memory contents after execution. |
-| `cycles` | An M-cycle breakdown of bus activity in the form `[address, value, type]` where type is either `"read"` or `"write"`. `null` indicates a cycle with no bus activity. | \ No newline at end of file
