From their “what’s this?” page:
What is this?
This site is dedicated to resources on video game decompilation. Matching decompilation is the process of writing source code (typically C or C++) that compiles to the same exact binary as the original. This usually requires using the same compiler as the original game, with all source code being written from scratch. Because matching decompilation is complex and time-consuming, dedicated communities have formed around the challenge. These communities have built a wealth of knowledge and tools to support the process.

Unless it means something else in this context, decompilation is reversing compilation process.
Basically taking the game and turning it back to source code. With source code it would be easy to fix some issues (of there are any), see how developers implemented certain things, and also be able to run the game on hardware that it never was running on before.

Via native code, not emulation, in case this wasn’t clear. This means that you can port the game to modern consoles and take advantage of individual gimmicks, like the wiiu tablet
