SGF - Salvathor Game Fabric (sgffabric)

The intent of Salvathor Game Engine is to facilitate the maximum creation of a new game.
It has several helpers:
Control configuration parameters, save and load game;
Control media: screen, keyboard, mouse and joystick;
control animations;
control features of the game: sounds, bitmaps, fonts;
Access control to the operating system: filesystem, folders, files;
Elaborations of menus;
control mods;
Support for bitmap fonts, truetype, mugen;
Artificial Intelligence: A * pathfinding;

I've developed some games with SGF:
OpenMugen - A clone of the famous fighting game
PacMan - also the famous Pacman
OpenMortal

SGF is fully programmed in C + + and SDL2 based primarily on, and with contributions from several free software.
Version 1.0 is already playable, but how do I develop myself, still needs some tweaking. Therefore, I gladly accept any help to make a SGF a real factory of games.
