I wish he would have listened/he had listened

[Vladv1]

Can I say " I wish he would have listened to me" instead of " I wish he had listened to me" , If I want to emphasise his unwillingness to listen? I've heard native speakers do that .

No, absolutely not. Don't do it, no matter how many native speakers you hear saying something similar. It's awful, and wrong.

You need past perfect after 'I wish'.

Can I say "I wish he would have listened to me" instead of "I wish he had listened to me" no comma here if I want to emphasise his unwillingness to listen? I've heard native speakers do that.

Note my corrections above. Don't put a space after opening quotation marks. Don't put a space before a comma or a full stop.
As jutfrank said, it's wrong. I notice it more amongst speakers of AmE but some BrE speakers incorrectly use it too.
