Modders successfully dissect Mario Party 4 code, paving potential path for GameCube games to run on PC.
Revamped and Refreshed
Dive into the whirlwind of excitement as we approach the June 5 release date for the Switch 2, and let's reminisce about my undying affection for the Nintendo GameCube - specifically, my yearning for the skies of Arcadia in those gorgeous purple boxes. Yes, I'm one of those die-hard GameCube fans, still harboring dreams of a re-release, while modders attempt to fill the void left by Ninten-don't.
Brace yourselves for the juicy details: Intrepid modders almost completely unraveled Mario Party 4, making it the first GameCube title to come this close to a total unraveling (via Techspot). The unofficial, certainly not Nintendo-backed effort spanned a jaw-dropping 18-month journey, leaving the possibility of a fan-made, natively-ported PC version on the horizon.
To set the record straight, this isn't emulation, which tricks software into operating on incompatible hardware. Decompilation, however, is a far more intricate reverse-engineering of the game's source code, serving as the initial step towards a playable PC port.
Despite not being equivalent to emulation, decompilation gets you closer to a game's code, providing more flexibility to manipulate retro console games on modern PC hardware. Who knows, maybe some ambitious modder will whip up a native online mode for this more-than-two-decades-old gem. We've already seen similar decompilations for Nintendo 64 games like Banjo-Kazooie and Paper Mario, but the Mario Party 4 project has proven to be an unique challenge for several reasons.
According to popular YouTuber MattKC Bytes, modder Rainchus initially ventured into decompiling the first Mario Party, a 1998 Nintendo 64 release, but hit a significant snag that required immense effort to overcome. Switching gears to the 2002 GameCube follow-up, as it turns out, the game's code was originally compiled without optimizations, offering easy access for a well-motivated modder.
I may have neglected my programming pursuits, but compiler optimizations essentially function as a shorthand for efficient code execution. Instead of lengthy strings of human-readable code, a compiler strips away unnecessary details while preserving the essential bits that your CPU needs to run the game efficiently.
Mysteries remain as to why the Mario Party 4 developers opted out of compiler optimizations. Perhaps humans are still crucial to debugging and QA, and the complex machine code can be challenging to decipher when hunting down software glitches.

'Debug symbols' are essentially navigational landmarks developers can use to locate troublesome sections of code. By implementing debug symbols in Mario Party 4, the source code became easier to explore, helping modders track down problematic areas more swiftly. Similar debug symbols in another Hudson Soft title, Hudson Selection Volume 4: Adventure Island, exposed even more of Mario Party 4's source code, making the decompilation project slightly less grueling.
At present, the decompilation project isn't quite complete – about 0.2% still awaits elucidation on complex functions that may not be essential to the game itself.
As fan projects go, the intricacies of decompiling a mid-tier party game like Mario Party 4 are sheer nerdiness at its finest. Let's just hope Nintendo never catches wind of this. The company tends to wield a fierce legal hand against emulation or modding of their hardware. The official Nintendo museum even allegedly emulated SNES games on a Windows PC, so projects like this have managed to slip under the legal radar for now. However, Nintendo Classics' recent expansion into GameCube games might mean these projects could be in jeopardy.
