Mario.Exe

I went into my fathers attic to find a really old dusty box. I opened it and found many old games. I found one particularly weird cartridge though... It had the face of Mario on it. It also had the words 'Super Mario.exe' on the front of it. I've decided to dump the rom online for you guys to play. It's very mysterious...

I've spent about 5 hours on this and I regret it. WARNING LOUD! WARNING LOUD! WARNING LOUD. WARNING LOUD! WARNING LOUD! WARNING LOUD. WARNING LOUD! WARNING LOUD! WARNING LOUD.
