Hi there.

I recently downloaded a copy of the original Kao the Kangaroo from GOG, but when I try to launch the game it crashes after a few seconds along with an error message reading: "d3d.EndScene error: DDERR_SURFACELOST". I suspect this is some kind of video card problem but it's not something I'm educated enough in to fix myself.

I'm using a 2020 MacBook Pro running Windows 10 through BootCamp, which can normally run similarly older PC titles without any problems, provided the right compatibility arrangements have been made obviously.

Would someone be able to help me with this?

Thanks a lot.

some tweaks solutions suggested in other threads (run in windowed by config file editing).
Some else general solutions, like DirectX9 and Legacy DirectPlay enable.

How about GoG fix it at their end?

How about no?

another solution here, but before dxwnd try narzoul draw compat or dgvoodoo

Why no? Isn't it GoG's responsibility to make sure the product they sell operates correctly on current systems?

Only if it's officially supported. Macs may or may not implement all DX features.

Also they could only fix it if they could reproduce it on one of their computers.
And no, as long as they don't hold the rights to the game, they are not allowed to distribute it in another way than the rights holder allows. They can however a) ask him for permission or b) to fix it.

Last but not least: Old games often cause problems on modern computers, most games with problems are from the late 1990s/early 2000 era, since the DirectX standard was not as strict as it is today and many programmers hacked the interface badly. One must be aware of that and be ready to do some adjustements.

Consoles don't have that problem. Old games don't run at all on modern consoles.
