Mario Forever is a freeware clone/unofficial remake of the famous Super Mario Bros. It was created by Buziol Games, and it was released for Windows only in 2004.
After many requests, we decided to publish this little game, quite similar to Super Mario Bros. 2. It is one of the most famous of the many Mario fangames but in one of its earliest releases. Mario Forever has been, in fact, updated several times, but the new releases are full of ads and other unwanted features. Version 2.16 comes only with a small installer. Despite its age, it is also fully working on Windows 10.
More than a clone, let's talk about an enhanced remake since the graphics are much better compared to the original NES game. Anyway, many elements have been preserved. The Mario feeling is there. Have fun!
