it is fixed and exhaust smoke added
the Alfa 33 by Kunos has the real sound (mostly). I have now boosted the gear sound a bit.
@Vassalfada
on a side note, I have Zolder09 converted from the FREE RealTimeRacing (Henry Roos "Simbin"). Since it was free, the conversion should be allowed on RD, right?
Actually, the Alfa 33 Stradale was powered by a 2.0l V8 (which they successfully enhanced for the 33/2 and 33/3 prototypes), so it sounds very different from the actual 33TT12 flat 12 engine.
Then, the Kunos 312/67 sound is still the closest thing we have in store for now.
Just for the reference, and the pleasure to listen to it, here's my TT12 sound playlist (the SC 12 was the latest evolution of the 33, it got the same engine as the TT but had a monocoque chassis instead of tubular):
As for the RTR Zolder, I don't think this version is that much better than the best Zolder we already have in AC.
Though, I can't really tell about the copyright, even if this track was distributed for free, it doesn't mean that it's automatically copyright free.
And to be honest, the ownership of this track is a bit particular, as it was commonly developed and financed by both SimBin and the RTR company, and even think there was a third partner involved
One sure thing is that the old SimBin company is not anymore and that the responsible persons are not part of the new S3S company (Henrik is long gone since 2012), so there's no one to ask except maybe Klaus Wohlfarth himself, but I certainly won't disturb him for such a demand
I would say that the conversion of this track is not more nor less risky than any other track conversion from others commercial games, sorry for not being able to be more specific
