I'm not sure about the king air, but Black Square is developing all new from scratch Bonanza, Baron and C208 with lots of variants.  You can read about it here

I don't if any of you have had any issues with the Analog King Air in MSFS 2024.  I attempted to use it yesterday (I have not flown it for a couple of weeks), and there was a large update May 15th...  It used to be that it worked by placing the original ASOBO King Air folder in the MSFS2024\MSFS2020\OneStore folder...

After trying a bunch of different ways to install the King Air, I ended up placing the original ASOBO King Air folder in the MSFS2024 Community Folder and it works.... 

Thought I'd let anyone know, if they are having recent issues, but was able to use the BlackSquare King Air in MSFS 2024 previously.

I tried to copy the FS2020 Asobo King Air Folder to the Fs2024 Community Folder along with BlackBox Analog enhancement, but can't see anything.

anyone know if still works?

I have flown the piston Duke quite a lot in MSFS 2024 recently. It worked flawlessly, certainly after the latest sim update.

Same here. It worked for a while and then ...last night... it stopped working. It would just hang MSFS 2024 and I had to use the Task Manager to exit the sim.



...

I know it’s a longshot, but would anybody be willing to email me the MSFS Asobo King air 350 file?
I only have 2024 installed and would like to make the black square 350 work in 2024 for the time being
Thanks
