SDL_DisplayFormatAlpha problem in PPPPPP (modded VVVVV game)

[Hakkitboss0]

I'm having a problem with modding VVVVVV.exe,but i ran into a bit of a problem. As I was attempting it, the program repeatedly informed me on some .dll files that were currently missing from the file. So as i continuously found, downloaded and placed each file where it was intended a last message popped up.  "VVVVVV.exe - Entry Point Not Found: The procedure entry point sdl_displayformatalpha could not be located in the dynamic link library sdl.dll". Now I'm no expert at .dll files, but from what it sounds like is that either 1. I have an SDL.dll file that supposedly doesnt meet the requirements of having "sdl_displayformatalpha" inside the SDL.dll file, OR 2. i dont have the  separate FILE "sdl_displayformatalpha" in the VVVVVV folder. If anyone has the answer to this please let me know. Thank you @Nexushakkit@gmail.com
