IngaSdl2 Engine is working well with your sdl2 port:

What is worth to mention from my side:
1. SDL_CreateRenderer with SDL_RENDERER_ACCELERATED or SDL_RENDERER_PRESENTVSYNC did not work. I needed to use SDL_RENDERER_SOFTWARE.

2. SDL_GetBasePath did not add the path separator at the end
see documentation:
* This returns an absolute path in UTF-8 encoding, and is guaranteed to
* end with a path separator ('\\' on Windows, '/' most other places).

Thx again beworld for the SDL2 port!
