Super Mario World 64 called also Super Mario Bros IV is an unlicensed Sega Mega Drive game. It is a loose attempt at porting the SNES game, Super Mario World to Sega's console without seeking endorsement from either Sega or Nintendo.

It's currently unknown who's developed Super Mario World 64, though some believe it was the same group behind Super Donkey Kong 99.

Oddly, for an unlicensed game, Super Mario World 64 features copy protection which makes it impossible to dump the ROM with the most usual techniques, such as using a Retrode. After a few years of unsuccessful attempts it was finally correctly dumped in 2012 and released a year later, though it doesn't work on emulators without emulation of the protection itself, or with a cracked ROM, with the protection removed.


In this game, Mario plays alone since Yoshi makes no appearance, only his feet and tail can still be seen on the title screen. Holding A button allows Mario to run, but the distance required before he starts running is longer than expected, making careful jumps that require a certain distance a bit tricky. Control in general is also very stiff.

Some of the music comes from the Mega Drive game, TaleSpin, while others from Super Battletank and Jeopardy, it is believed that Super Mario World 64 uses the GEMS sound driver since the games which feature the original songs use it.
