[PATCH] n64cart: use strscpy() in n64cart_probe

From: Thorsten Blum

Date: Sun Apr 26 2026 - 08:00:38 EST


strcpy() has been deprecated¹ because it performs no bounds checking on
the destination buffer, which can lead to buffer overflows. While the
current code works correctly, replace strcpy() with the safer strscpy()
to follow secure coding best practices.
