+## Game Boy Devices & SoC Revisions
+
+I could not find any information on Game Boy hardware compatibility for this test suite.

+## Exit Condition
+
+TODO
+
+## Test Success/Failure
+
+Test success/failure can be determined by
+[screenshot](https://github.com/c-sp/gameboy-test-roms/tree/master/src/turtle-tests/)
+comparison.
+
+To create comparable screenshots,
+your emulator should calculate colors as follows:
+
+- `#000000`, `#555555`, `#AAAAAA` and `#FFFFFF` are used for the four DMG LCD
+  shades
+- LCD shades for CGB compatibility mode are:
+  - background: `#000000`, `#0063C6`, `#7BFF31` and `#FFFFFF`
+  - objects: `#000000`, `#943939`, `#FF8484` and `#FFFFFF`
