I'm would like to show you a software i'm developping. It's a simple retro game's maker & player. No source code needed. Just put your media inside the good folders, and after, edit (or create) configuration files.
Notice that you can't do all kind of games, it's only for retro games. There is no physics, no 3D, and i think i'll not add particles. But the advantage is you have not to program.
When this program will be done, i will program a simple UI to import media easily, to configure your games, and to test them by running the player.
'Retro Gamer Virtual Machine' accept multiples games in the same folder, and looks like a strange emulator for old computers.
You can take a look at it in this video. They are still some bugs, some stuffs not done, and i make four games together to test the the virtual machine player.

And inside one of those files :
