I have seen those horrors. They managed to botch as many things as possible. (IIRC it cannot use well PC HW at all) Analysis: http://www.pcgamer.com/final-fantasy-xiii-and-xiii-2-port-analysis-durantes-verdict/

Original FF VII was updated for PCs fairly recently. (So it actually can run on anything newer then ancient HW with ancient drivers because of 8-bit transparent textures under fixed pipeline) Will be watching the remake...
