1.0 Beta I think. Just try compile this code in Delphi, then compile it in Lazarus:

[pascal]
program Test;
uses SDL;

var
surface : PSDL_Surface;

begin

SDL_SetColorKey(surface, SDL_RLEACCEL or SDL_SRCCOLORKEY, SDL_MapRGB(surface.format, 255, 0, 255));

end.
[/pascal]

Runtime error doesn't matter.


-Edit-

Ok, I read some sources and I find where be an error. Well it should be "surface^.format" not "surface.format". Now everything should works fine
