1) The current climate (with Nintendo being pissed) is hardly one where people should share links to ROMs;
2) Either way, sharing links to illegal content is not allowed on this site. Feel free to find the past forum threads with the OP of those threads asking the same question as you. You will find those locked.

So, really, it's not a question of "helpfulness" but rather one of common sense and sticking to the rules.

That said, "'game name' rom" is not exactly the hardest thing to type in Google, now, is it?
