I don't if this is old but I was just surfing the web and found this game called Mario Forever for pc by Softendo!

It doesn't have any viruses. 

you may download it here: http://www.softendo.com/game/view/name/MF

Also i would like to ask if this type of posts are allowed and are okay with the site.. If this type of thread is not allowed and considered spam please delete it and please do not ban me....

As long as it is legal than the post is fine

actually i read the terms condition and it said nothing about nintendo and it said that this game is free and so anyone may use it but not sell it... so i guess it is fine.. yay

It's a fan game, there's nothing new or strange about finding a free pc Mario game. :P

considering it is a fan game, the graphics are not that far off of NSMB Wii
