Kingdom Hearts has anti-piracy.
How are you trying to play it? (Emulator or flashcart)https://www.romulation.org/forum/index.php?topic=23731.0First post tells you how to fix it,and there's even an already patched rom link there.

For MySims, search the Trading Station. https://www.romulation.org/forum/index.php?board=55.0 If you can't find a working link there, then search Google for it.
