First, I should outline the article structure. Start with an introduction about the game, its release, platform, and maybe clarify the confusion. Then talk about the game's mechanics, features, and gameplay. Mention the story if any. Discuss the challenges of emulating PS2 games on Wii, or if there's a way to play Zero Gravity on Wii. Maybe the user is looking for how to install the ISO on a Wii. I need to provide accurate information, maybe point to legal resources or emulation considerations.

Sum up the article by highlighting the game's legacy and why it's still remembered. Maybe a conclusion that wraps up the confusion and suggests legal ways to play. Make sure the tone is helpful but respectful of copyright laws.

I should also check the original systems for Zero Gravity. PlayStation 2 and Xbox. So not a Wii game. The user might have misremembered. Maybe they wanted a guide on how to play it on Wii via emulation. But that's not legal unless they own the disc and use their own copy. I have to be cautious with that info.

: If you’re a fan of zero-gravity racing, Sonic & All-Stars Racing : The First Lap (2021) features updated mechanics and modern graphics—worth a try! Disclaimer : This article provides information for educational purposes. Always comply with local laws regarding digital copyright.

Include some technical details: characters, vehicles, tracks, zero-gravity sections. Maybe some gameplay differences between Riders and Zero Gravity. Then address the Wii part, explaining the platform confusion. Also, mention alternatives if they want to play on Wii, like similar games or using emulators with PS2 ROMs. But again, need to stay within legal guidelines.

Wait, the user specified "ISO Wii," but the game wasn't originally on Wii. Should I mention that? Yes, because others might be misled. Also, mention copyright issues if they're downloading an ISO. Emphasize legal aspects here. Maybe suggest purchasing a physical copy if possible.
