Gameboy CPU (Sharp LR35902) Tests

Test data for developers of Gameboy emulators. These files are designed for unit testing the CPU of the Gameboy (Sharp LR35902) in isolation and don't expect any other hardware components to be implemented.

• alu_tests (Removed since c7b4e6a) - Contains full test data for the 8-bit ALU operations of the Gameboy CPU.
• v1 (Deprecated since c7b4e6a) - Contains randomly generated test data for all Gameboy CPU instructions.
• v2 - Updated randomly generated test data for all Gameboy CPU instructions in the same format as https://github.com/TomHarte/ProcessorTests.

The main differences between v2 and v1 are:

• The test format now correctly matches https://github.com/TomHarte/ProcessorTests.
• Register and RAM values are recorded as decimal numbers instead of hexidecimal to make them easier to parse.
• The tests now assume you're doing a decode-execute-prefetch loop instead of a fetch-decode-execute loop.
• Improved coverage of CB opcodes.
• Removed STOP, HALT, EI, DI as the tests are not meaningful.

Please see the README in each individual folder for more details.
