Yes, I know it is outdated and should be avoided, still, it would save me some time of rewriting the code since I could use standard SDL blit function.
Is this flag even working? I have strange problems (textures messed up, also was unable to properly update the screen since SDL_UpdateRecs fills the screen with write). Was this flag completely removed (still it partially works to me...)? Are there any problems with certain implementations/IDSes/OpenGL versions compatibility (like VC++ Express OpenGL version)?
Or to put it shorter, how can I make it work nowadays?
