@neobrain Did you manage to solve the problem with linear interpolation? I was reading through the thread and couldn't resist posting.

Heh, I didn't expect anyone to ever find that post again :p

Anyway, in addition to what I said in the post that Shonumi linked to, this is also implemented in Dolphin now, in the WriteTevRegular function at https://github.com/dolphin-emu/dolphin/blob/master/Source/Core/VideoCommon/PixelShaderGen.cpp#L951 . That one is a bit more generic than what I was writing before.

That was only (the already known) part of the issue, though.
