For decades, Mario has been the undisputed king of platforming, a red-capped icon whose adventures have graced nearly every Nintendo console. We know the heavy hitters: Super Mario Bros., Super Mario 64, Super Mario Galaxy. But nestled within the vast Mario universe are gems that, for reasons often baffling, haven’t received the same universal acclaim. Now, one such spritely secret has finally graced Nintendo Switch Online, and it’s high time we gave it the spotlight it deserves.

The game in question is none other than Super Mario Advance 4: Super Mario Bros. 3.

Yes, you read that right. While many might associate the “Super Mario Advance” series with Game Boy Advance ports, Super Mario Advance 4 is more than just a simple remaster. It’s a lovingly crafted package that breathes new life into one of Mario’s most ambitious and innovative titles, and its recent addition to the Nintendo Switch Online service is a genuine treat for both seasoned fans and newcomers alike.

Let’s be clear: Super Mario Bros. 3 itself is not underrated. It’s a landmark title, a masterclass in 2D platforming that introduced iconic power-ups like the Super Leaf, the Frog Suit, and the Tanooki Suit, forever changing the Mario formula. It was a bold evolution, brimming with secrets, varied worlds, and a level of complexity that felt revolutionary at the time.

However, the Super Mario Advance 4 version, and by extension, its Switch Online debut, often gets overshadowed. Perhaps it’s the existence of the original NES version, readily available through various means. Or maybe the GBA’s graphical style, while charming, didn’t resonate as strongly with some as the pixel-perfect NES original. But to dismiss it would be a grave mistake.

So, what makes Super Mario Advance 4 so special, and why is its Switch Online arrival cause for such quiet jubilation?

Firstly, the enhanced visuals and audio are more than just a fresh coat of paint. The sprites are larger, more detailed, and boast smoother animations. The music, while faithful to the original, sounds richer and more dynamic on modern hardware. It’s a presentation that feels both nostalgic and refined, offering a comfortable and visually pleasing way to experience a classic.

But the real magic, the element that truly elevates Super Mario Advance 4 and makes it a must-play on Switch Online, lies in its integration of the e-Reader functionality. For those unfamiliar, the original GBA release included a special feature where players could scan e-Reader cards to unlock bonus levels and mini-games. While this was a fascinating, albeit niche, aspect of the original GBA release, Nintendo, in their infinite wisdom, has managed to recreate the effect of these e-Reader cards within the Switch Online version.

This means that players can now access a curated selection of these bonus stages directly within the game, without needing any external hardware. These aren’t just simple reskins; these are cleverly designed levels that offer fresh challenges, new enemy placements, and even unique gameplay mechanics that expand upon the already robust Super Mario Bros. 3 experience. Imagine revisiting the familiar worlds with a twist, or tackling entirely new challenges that would have otherwise been locked behind the now-defunct e-Reader.

Furthermore, the inclusion of Mario Bros. classic arcade game as a bonus mode is another fantastic addition. This two-player competitive mode offers a different, yet equally addictive, brand of gameplay, providing even more value to the package.

For many, the addition of Super Mario Advance 4 to Nintendo Switch Online is a chance to rediscover a beloved game with a newfound layer of depth. It’s an opportunity for those who might have missed out on the GBA version to experience these e-Reader-inspired bonus levels for the first time. It’s a testament to Nintendo’s commitment to not just porting classics, but to intelligently enhancing them for modern audiences.

In a landscape often dominated by reboots and remakes, the arrival of Super Mario Advance 4 on Switch Online feels like a genuine discovery. It’s a reminder that even within the most celebrated franchises, there are still wonders to be unearthed, and that sometimes, the most exciting new additions are the ones that have been quietly waiting in the wings. So, fire up your Nintendo Switch, dive into the Expansion Pack, and give Super Mario Advance 4: Super Mario Bros. 3 the attention it so richly deserves. You might just find yourself surprised by this wonderfully underrated gem.
