These 11 SNES Games are Now Co-op

1. Super Mario World Two-Player Simultaneous Co-op Hack

This hack breathes new life into a beloved classic by introducing simultaneous multiplayer gameplay. The original Super Mario World relied on an alternating turn system, but this modification allows Mario and Luigi to team up on the same screen at the same time. Together, players can navigate through Dinosaur Land in a way that transforms the traditional single-player experience into a cooperative journey.

Number of Players Supported

The hack supports 2 players, with each controlling their own character throughout the game.

Type of Co-op

This is a local simultaneous co-op experience. Both players share the same screen, interacting with the environment in real time, which opens up entirely new ways to strategize and collaborate.

Gameplay Features

The cooperative mechanics completely shift how players approach the game’s familiar levels. For example, in Yoshi's Island 1, one player can distract enemies while the other focuses on collecting coins and grabbing power-ups. To accommodate two players, adjustments have been made to the camera and level design, ensuring both characters remain visible - although occasional graphical glitches can occur if they stray too far apart. Additionally, power-ups and progress are shared, meaning both players benefit from what’s collected, fostering a true sense of teamwork.

Compatibility with Hardware or Emulators

This hack is designed primarily for SNES emulators like SNES9x and bsnes, which handle the custom code and dual inputs effectively. For those who prefer playing on original hardware, it’s compatible with SNES flash cartridges such as the EverDrive or custom reproduction cartridges. The hack is distributed as an IPS patch, which must be applied to a legally obtained Super Mario World ROM. If you’re after an authentic hardware experience, custom cartridges can also be purchased from specialized retailers like BJ's Game Vault.

Up next, we’ll dive into another classic reimagined for multiplayer fun.

2. Secret of Evermore Two-Player Edition

The Secret of Evermore Two-Player Edition breathes new life into the beloved single-player RPG by introducing a simultaneous co-op mode. In this version, one player controls the protagonist while the other takes charge of his trusty canine companion. Together, they engage in real-time combat, explore diverse environments, and solve puzzles as a team. This dynamic setup adds a fresh layer of strategy, requiring players to manage resources and tackle challenges collaboratively.

Number of Players Supported

This hack allows two players to join forces on the same SNES system, making it a shared adventure from start to finish.

Type of Co-op

The gameplay features simultaneous local co-op, where both players actively participate throughout the journey. No waiting for turns - both characters are always in the action.

Gameplay Features

The cooperative mode introduces a new level of teamwork. Players must coordinate item usage, manage health, and plan spellcasting together. While the original story remains intact, the addition of co-op gameplay provides a fresh perspective, especially for fans who have already experienced the single-player campaign.

Compatibility with Hardware or Emulators

The hack works seamlessly on popular SNES emulators like SNES9x and ZSNES. For those who prefer the authentic feel of original hardware, it’s compatible with flash cartridges and reproduction carts. Devices like the EverDrive series allow players to enjoy the game on an actual SNES console.

For collectors, BJ's Game Vault offers custom cartridges featuring ROM hacks like this one, with prices ranging from $40 to $80, depending on the quality and packaging. To get started, players need a clean Secret of Evermore ROM and the Two-Player Edition patch file. Tools like Lunar IPS can apply the patch, creating a modified ROM ready for use on emulators or flash carts. This makes the co-op adventure accessible to retro gaming enthusiasts everywhere.

3. Seiken Densetsu 3 (Trials of Mana) Three-Player Hack

The Seiken Densetsu 3 Three-Player Hack is a remarkable modification for the SNES that breathes new life into the classic Japanese RPG. Originally designed as a single-player game, this hack transforms it into a three-player cooperative adventure, where each player controls one of the main party members. The story and core mechanics remain intact, but the interface has been cleverly adjusted to accommodate multiplayer gameplay.

Number of Players Supported

This hack allows up to three players to join in simultaneously, a huge leap from the original single-player setup. Each participant takes charge of a specific character, removing the need for AI companions and giving players full control.

Type of Co-op

The hack introduces local co-op gameplay where all three players can act independently during both exploration and combat. This format makes teamwork essential, especially when timing and coordination are needed in battles or tricky scenarios.

Gameplay Features

Multiplayer adds a layer of strategy and engagement. Each player manages their character's abilities, inventory, and magic. For instance, during intense boss fights, one player might focus on healing while the others handle offensive tactics. Beyond combat, real-time collaboration is key for solving puzzles and navigating the game’s world, making for a fun and interactive social experience.

Compatibility with Hardware or Emulators

To play on an original SNES console, you’ll need a multitap accessory to connect three controllers. If you’re using emulators like SNES9x or bsnes, the hack works seamlessly as long as the controller inputs are properly configured. Save states can also help avoid potential syncing issues during gameplay.

For retro gaming enthusiasts, BJ's Game Vault even offers custom cartridges with this hack pre-installed. This makes it easier to enjoy the multiplayer experience on original SNES hardware without the hassle of manual setup.

4. The Legend of Zelda: A Link to the Past Online/Co-op Hack

The Legend of Zelda: A Link to the Past Online/Co-op Hack breathes new life into one of the most cherished SNES classics, turning its solo adventure into a multiplayer journey. This modification allows two players to explore Hyrule together, solving puzzles and battling enemies side by side in real time. It’s a fresh take on a beloved game, offering an online co-op experience unlike traditional local hacks.

Number of Players Supported

The hack is designed for two players, with each controlling their own version of Link within the same game world. This two-player setup ensures smooth gameplay and keeps the experience stable and well-synchronized.

Type of Co-op

This is a simultaneous online co-op hack, meaning players can connect remotely and play together in real time. Both players can move independently, explore different parts of the map, and collaborate to tackle challenges. Whether it’s solving puzzles or defeating enemies, this setup is perfect for friends who want to relive the adventure from different locations.

Gameplay Features

One of the standout features is the real-time synchronization of inventory, dungeon progress, and the game world. If one player collects an item or unlocks a door, the changes are reflected instantly for both players. This creates a true sense of teamwork. For example, during dungeon runs, one player might focus on distracting enemies while the other solves a switch puzzle or gathers keys.

Some versions of the hack add even more variety, including player-versus-player modes, options for shared or separate inventories, and custom rule sets to spice up the cooperative gameplay with new challenges and strategies.

Compatibility with Hardware or Emulators

This hack is designed to work with emulators that support netplay, such as SNES9x and BizHawk. Because of its reliance on online connectivity, it’s not compatible with original SNES hardware. To get started, players need a clean A Link to the Past ROM and can apply the co-op modification using standard ROM patching tools. Guides and troubleshooting help can be found on the hack’s GitHub page.

For collectors, BJ's Game Vault offers custom cartridges that provide a plug-and-play option, ensuring compatibility and making for a great addition to any retro gaming collection.

However, there are a few known issues. High network latency can sometimes cause desynchronization, and rare softlocks may occur if both players trigger scripted events at the same time. To avoid these problems, it’s best to use a stable internet connection and save progress frequently.

5. Super Mario Kart Co-op/Double Dash Hack

The Super Mario Kart Co-op/Double Dash Hack takes the classic SNES kart racing game and flips the script. Instead of competing against each other, this fan-made modification encourages teamwork by introducing a cooperative mode reminiscent of the Double Dash experience. Players now team up to tackle races, blending strategy and coordination for a fresh twist on the original formula.

Number of Players Supported

This hack is designed for two players, allowing them to share control of a single kart in real-time. The gameplay emphasizes teamwork, making communication and coordination key to success.

Type of Co-op

The hack offers local simultaneous co-op gameplay, where both players are actively engaged on the same screen. Forget turn-based play or online competition - this is all about working together in real-time to conquer the track.

Gameplay Features

The core of this hack is its unique division of responsibilities. One player takes the wheel, focusing on driving, steering, and positioning. Meanwhile, the second player handles item management, deploying shells, bananas, and other power-ups at just the right moment. This setup adds a layer of strategy that wasn’t present in the original Super Mario Kart.

For example, while the driver navigates a tricky curve, the second player might strategically drop a banana peel to thwart a rival. Success hinges on how well the players can synchronize their efforts, as both share the same progress and race results - victory or defeat is a shared experience.

Some versions of this hack even include custom tracks or visual enhancements, giving the game a fresh look and feel. These additions make the cooperative gameplay even more engaging and distinct from the original.

Compatibility with Hardware or Emulators

This hack is best enjoyed using popular SNES emulators like SNES9x or bsnes, which fully support its multiplayer functionality and custom modifications. To ensure smooth gameplay, it’s recommended to use the most up-to-date versions of these emulators.

For those who prefer the authentic feel of original hardware, BJ's Game Vault offers reproduction cartridges and custom solutions. These options let retro gaming enthusiasts enjoy the hack on genuine SNES consoles without needing to manually patch ROMs.

To get started, players will need a clean U.S. version of the Super Mario Kart ROM, the co-op hack patch (commonly in IPS or BPS format), and a patching tool like Lunar IPS or Floating IPS. Once patched, the modified ROM can be loaded into an emulator or transferred to a flash cart for play on original hardware.

Feature Comparison Table

Here's a breakdown of some standout features for each hack:

Technical Requirements Breakdown

Most of these hacks run smoothly on popular SNES emulators like SNES9x and bsnes. For the Seiken Densetsu 3 hack, multitap support is essential to connect three controllers. The Zelda: A Link to the Past online hack requires either a web-based emulator or netplay-compatible software, which may involve additional setup.

Player Count Considerations

While most hacks support two players, the Seiken Densetsu 3 hack stands out by allowing three players to join in on the action.

Installation Complexity

To get started, you'll need to apply the appropriate .ips or .bps patch to a clean ROM file. However, the Zelda online hack is a bit more involved, often requiring server configuration or the use of a specialized web-based emulator.

For those who prefer gaming on original hardware, reproduction cartridges from options like BJ's Game Vault provide a hassle-free experience. These cartridges come pre-patched and are fully compatible with SNES consoles, saving you the trouble of manual ROM patching.

Performance and Compatibility Notes

Modern emulators handle these hacks effortlessly, ensuring smooth gameplay. On original hardware, performance can vary - Seiken Densetsu 3 may experience slowdowns during intense battles. For online hacks like Zelda, a stable internet connection is crucial to avoid lag or disconnections. By considering these factors, you can pick the hack that best matches your setup, blending retro gaming with a modern twist.

As the retro gaming community continues to expand, co-op ROM hacks highlight how creativity can keep gaming history alive while aligning with modern preferences for social play. These innovations ensure that the legacy of 16-bit gaming remains vibrant, offering something meaningful for both seasoned players and newcomers alike.

FAQs

How can I use a ROM hack with my SNES game, and what tools do I need?

To modify an SNES game with a ROM hack, you’ll need two key components: a clean ROM file of the original game and a patch file for the hack, typically in IPS or BPS format. You’ll also require a patching tool like Lunar IPS or FLIPS to merge the hack with the original ROM. Once the patching process is complete, you can enjoy the altered game using an SNES emulator or a flash cartridge compatible with your console.

It’s important to ensure you’re using ROM files that you legally own and verify that the hack is compatible with the specific version of your game. For those who love retro gaming, stores like BJ’s Game Vault offer custom cartridges and rare game hacks, making it easier to expand and enhance your collection.

Can I play these co-op ROM hacks on modern devices, or do I need an original SNES console?

Yes, you can enjoy these co-op ROM hacks on modern devices! Most of them work seamlessly with popular SNES emulators, which are available for PCs, Macs, and even smartphones or tablets. If you're someone who loves the retro vibe, you can also play them on original SNES hardware using custom cartridges or flash carts. Just double-check the requirements for each ROM hack to ensure it’ll run smoothly on your setup.

What challenges might come up when playing co-op ROM hacks with friends?

Playing co-op ROM hacks can be a blast, but there are a few bumps you might hit along the way. Compatibility problems are a common hurdle - if everyone’s using different emulators or devices, things might not run smoothly. To dodge this, make sure everyone is using the same setup before diving in.

Another challenge is syncing gameplay during online co-op. Even a tiny bit of lag or latency can throw off the experience, which can be frustrating in fast-paced moments.

On top of that, not all ROM hacks are built with multiplayer in mind. This can lead to glitches or odd behavior popping up during your session. To keep things running smoothly, try testing the game ahead of time and stay in touch with your friends during gameplay. That way, you can quickly tackle any hiccups together.
