Notes

- Display cover was missing
    -> Cleaned old glue
    -> Attached replica part
- LCD had two missing columns at the left border:
    -> TODO: repaired
- The blue print on the shell (Nintendo GAMEBOY, START, SELECT, A, B) dissolves in alcohol
  much more easily compared to other Gameboys and smears across the shell.
    -> Could be a sign that the shell got swapped with an non-original part.
       But except for the dissolving of paint it looks genuine.
- Link port cover was missing:
    -> Attached replica part
