Trying (and failing) to get my own mp3s playing consistently on the radio in the mac appstore version of GTA SA, I had occasion to peek in the installed directory structure.

I was pretty surprised to see a familiar-looking wine style layout there.

I didn't really look into it, so I don't know what the exact situation is, but looks like the future might have already happened in that case.

I think he's referring to developers making a quick port using Wine as a wrapper similar to Cider.

Cider sucks, though.

Yes, this is what I meant. Cider does suck, because Cider is based on a proprietary fork of a 7 year old branch of the Wine code and couldn't keep pace with the open source version. There's a reason Transgaming abandoned Cedega as a consumer product, and it's been that free Wine has been vastly superior for a while.

Codeweavers has already moved into the porting space using their expertise around free Wine, and perhaps not surprisingly Transgaming has begun to pivot into completely different areas.
