What dialects change ます into やす, as in these examples:

>   * 「何が **出やした** か…？見ておくんなせェ」
>   * 「そう **決めやした** ね…？」
>   * 「ならあちらさんの勝ちだ…今夜は逮捕 **しやせん** 」
>

It appears to be Edo dialect. Is that correct?

What dialects change ます into やす?
Yes, one can call it Edo dialect and all of your examples look Edo/Tokyo as
well. Today, 「やす」 is no longer used by many in real life around Tokyo. It is
more "known" as the honorific sentence-ender in the underworld in fiction.

I would need to point out, though, that the auxiliary verb 「やす」 was originally
a Kansai phenomenon. It is still used in Kyoto in polite imperatives.
