Ok, I decided to give Z18 a go, and I have the typical nOOb question:
I unzipped the original S2 0.5Z in a "LFS TEST" folder, ran the "Z to Z18" exe, all is well, splash screen says Z18, I unlocked it, but HOW do I transfer all my wheel settings, and axis assignments from S2 0.5Z to Z18 ??

I copied the cfg.txt but didn't do it.

uh-oh...maybe it's stored somewhere in some misterious Logitech folders, and it has nothing to do with the game ??

I'd recommend copying the whole LFS Z folder and then patching it (that's how I did it).

Yes, that's the way I was starting...but I remembered a post from Scawen saying to start from a vanilla LFS, to minimize "strange" bugs.

I have tons of changed skins, dds, sounds, scripts...in that way, if I get a bug, I can't be sure why I got it...

So if you want to start "from scratch", you can set up your wheel settings again... or just open two LFS windows and manually re-set it.

So I guess there is not a INI file to copy between folders...ok I'll bite it.
I was thinking I could copy Logitech's profile in some ways...

Thanks.

Copy the data/misc folder I think.

Yupp, Data/Misc for controller/player settings.
Data/Setups for the car setups
Data/Colours, for the colors (if u ever changed them)
And maybe the Data/Skins*, if u want the skins

Yepp, "misc" did the trick. There are still some buttons to be worked out.
Of course "setup" and the others too.

Thanks all.
