Yes, he normally still has the source code, so he can just recompile the game engine without that DRM.
because the source code belongs to ELB itself
like with every other company that you're working at as a programmer
Well he did get the source code of XXL2 to make the remaster.
Maybe even the source code of a beta/release candidate of the game.
The remaster still uses the Kal engine
and the remaster doesn't use the kal engine
just the kal objects / structures
I'm pretty sure it uses the Kal engine, but modified
The code for game logic, AI, pathfinding and collision should be the same as the original game.
But for the graphics and sounds, the original used Renderware.
But obviously Renderware doesn't exist anymore, so they had to replace it with OEngine.
but I'm still not sure if they actually had the whole source code from ELB
I think it was said that they got the source code from archives.
Oh, I didn't know about that
Im 90% sure adrien is right since the enemy ai and collision system feels exactly like xxl2
also the game does use the K .KWN files for collision since there is no trace of any other collision file in the files
