Play Mario 7-in-1 (Mapper 04) Online
A small Mario game collection featuring multiple variations of platforming adventures.

Game Overview
Mario 7-in-1 (Mapper 04) is a weird little NES rom hack that mashes up classic platforming with some unexpected twists. At first glance, it looks like a standard Mario game, but then you notice the levels are scrambled—familiar enemies in places they shouldn't be, power-ups that behave differently. It's disorienting in a way that keeps you on your toes.
The controls feel slightly off, like Mario's momentum is just a little heavier than you remember. Some jumps require more precision than the original games, which can be frustrating when you're used to the rhythm of vanilla Mario. But there's something oddly compelling about seeing familiar sprites rearranged into new challenges.
If you're into rom hacks that remix rather than reinvent, Mario 7-in-1 (Mapper 04) has a strange charm. Just don't expect it to play like the classics.
