Yes, this is what I wanted to emphasize.

My intent wasn't to say that the 'lack of z-buffering' statement was incorrect (it's still true), but that there's a fundamental issue behind it, the visible/hidden surface determination, and now it depends on the developer's implementation. I believe this is overlooked on non-technical sites.

With this, I just wanted to make it more informative for the reader. I don't think the question is if the PS1 has a z-buffer or not. Sure, z-buffering is a solution, but there's the reasoning behind it that I wanted to transmit it to the reader.

Anyway, that's just my opinion.
