Have fixed the list now based off the following info:
I blame my fingers haha.
Yes, that's the version that we don't have on AC (and I would have hated it too as a driver).
I did forget that someone has tried to make an 80's Brands Hatch (so probably should include that). It's not perfect, but it is there.
As for the Long Beach layout - Says 1988, but from the map file it looks to also be the 1975-1981 layout we already have.
1988 used a layout that is essentially a hybrid between the modern day one, and the 1983 layout.
Ahh, for some reason I had that down as the 1967 version, but you're absolutely right.
EDIT: And, I'm also going to say that there is a Zolder 1975-1982 layout.... (It is on Breathe's list)
Essentially it's a Faux version of the modern day Reboot Team edition by weikangcai, with the first corner complex in it's old form, the Kleine chicane in it's older form (I spelt it right this time!), and the removal of the Villeneuve chicane, and the original version of the Jacky Ickxbocht.
So I'm going to consider that we are only missing the initial form of Zolder that Formula 1 used (which is essentially
this, but with the addition of the Kleine chicane)
