By 2020, many gigabytes of internal Nintendo data leaked onto the wider Internet. Known as “Gigaleak”, it contained source codes and assets from many games. Using data from this leak, a group of enthusiasts have put together high-quality renditions of SNES Super Mario World Original Sound Tracks (OST).
The work was made possible when source code from the Gameboy Advance remake of Super Mario World was found in the leaked data. The source code included the names of the samples, which were the same as those used in the original SNES game. This allowed the team to find the original samples among gigabytes of leaked files.
We wondered what would be done with all that code, and speculated that it would be a poison pill for the emulator scene. This type of hack was not even on our radar, and we are happy to see the project come to light. The reproduced songs have a completely different quality than the original SNES soundtrack. This is largely because the samples do not need to be compressed or cut down to fit on a cassette and work with the console̵
Regardless of the changes, it’s interesting to hear a more complete, rounded sound of these classic songs. It reminds us a bit of the later CD console era, when sound designers were able to break free from the limitations of previous hardware. Of course, we’re still bending to change the chiptune – and this MIDI Gameboy mode is a great place to start if you’re curious. Video after break.
