Heh, the first version of the game, when it was still 2D, was written with SDL - then we switched to TGE to go 3D. Now we may go back to SDL in some sense - the irony, eh? Can you give me any pointers/links of how to do an SDL build? Is there an #ifndef somewhere? Also, I talked to another team developing with T3D, they said they made rendering freeze and other issues go away by switchting to D3D11. I don't believe there is an official implementation of this yet, is there?
