Best Smash 64 Online Multiplayer Alternatives
For playing Super Smash Bros. 64 online with friends, the top pick is Project 64 with the Netplay build and a dedicated matchmaking service like Smash 64 Online (S64O) or Fightcade. These give you the original game with rollback netcode (via the Slippi-style community servers) and a built-in player base, making it the closest thing to a seamless online experience without needing to configure port forwarding or use third-party workarounds.
What to Look For
When choosing an alternative for Smash 64 online, the real criteria are:
- Netcode quality: Rollback netcode is far superior to delay-based for competitive play. Look for options that use rollback or at least have a strong peer-to-peer connection with low latency.
- Matchmaking and community: A built-in ladder or matchmaking system (like S64O’s ranked queue) saves you from manually finding opponents on Discord. Active communities mean you can always find a game.
- Ease of setup: Some options require you to source a ROM and configure plugins. Others, like Fightcade, automate most of the process.
- Controller support: Native support for modern controllers (GameCube, Xbox, PS4/5) without extra mapping tools is a huge plus.
- Accuracy and features: Does it support the original N64 controller’s analog stick properly? Does it have widescreen hacks or HD textures? These are nice-to-haves but not deal-breakers.
1. Project 64 Netplay + Smash 64 Online (S64O)
Strengths: This is the gold standard. The S64O client is built on a modified Project 64 emulator with rollback netcode (like Slippi for Melee). It has a built-in matchmaking ladder, a ranked mode, and a large active player base. You get the authentic N64 experience with modern netcode.
Trade-offs: You must provide your own Smash 64 ROM (a legal copy you own). Setup requires a few steps: download the S64O client, place the ROM in the correct folder, and configure your controller. The interface is barebones, and the community is focused on competitive rules (no items, certain stages).
Who it suits: Players who want the most authentic and competitive Smash 64 experience online. If you’re serious about ranked play, this is the only real choice.
2. Fightcade
Strengths: Fightcade is a multi-platform retro gaming netplay client that supports N64 games, including Smash 64, via its built-in emulator (Mupen64Plus). It uses rollback netcode and has a simple matchmaking lobby system. It’s free and open-source, and it handles most of the technical setup automatically.
Trade-offs: The N64 support on Fightcade is less polished than S64O. You still need a ROM, and the netcode is not as finely tuned for Smash 64 specifically. The community is smaller and less focused on Smash 64, so finding matches can be slower.
Who it suits: Players who already use Fightcade for other retro games and want a simple, all-in-one client. Good for casual play with friends, but not ideal for ranked competition.
3. Parsec (with a friend hosting)
Strengths: Parsec is a low-latency remote desktop tool. You can run any emulator (like Project 64) on your PC and have a friend connect to your session. It’s incredibly easy to set up, and you can play any game, not just Smash 64. It also supports up to 4 players if you have a good upload speed.
Trade-offs: Parsec is not a matchmaking service; it’s a peer-to-peer connection tool. You need to coordinate with friends manually. The host’s internet upload speed determines the quality for everyone. It also has a slight input lag compared to dedicated netcode, and it’s not ideal for competitive play.
Who it suits: Casual groups of friends who want to play together without dealing with ROMs or netcode settings. Best for 2-4 players on a decent connection.
4. RetroArch (with Netplay)
Strengths: RetroArch is a multi-system emulator frontend that supports N64 cores (like Mupen64Plus-Next). It has built-in netplay that works reasonably well for Smash 64, especially if both players have stable connections. It’s free and cross-platform.
Trade-offs: RetroArch’s netplay is not rollback; it uses delay-based netcode, which can feel laggy on higher ping. Setting it up requires configuring the core, netplay settings, and possibly port forwarding. The interface is not beginner-friendly.
Who it suits: Tech-savvy players who already use RetroArch and want a free, no-frills netplay option. Not recommended for competitive play.
5. OpenEmu (macOS only) + Netplay
Strengths: OpenEmu is a beautiful, user-friendly emulator for macOS that includes N64 support. It has a built-in netplay feature (using a peer-to-peer system) that is simple to launch from the menu.
Trade-offs: Netplay is not rollback and can be unstable. It’s also macOS-only, so both players need Macs. The N64 core is not as accurate as Project 64, and the netplay feature is not actively maintained.
Who it suits: Mac users who want a simple, clean interface for casual netplay with friends. Not for serious competition.
6. Super Smash Bros. Ultimate (Switch) as a Substitute
Strengths: If you’re open to a modern alternative, Super Smash Bros. Ultimate on Nintendo Switch has excellent online play (with a wired connection) and a huge player base. It includes many classic stages and characters, though not the exact N64 physics.
Trade-offs: It’s not Smash 64. The gameplay is different (faster, more mechanics). You need a Switch, the game, and a paid Nintendo Switch Online subscription. The online matchmaking is not as precise as S64O’s ranked ladder.
Who it suits: Players who want a modern, polished online experience and don’t mind the different gameplay. Good for those who already own a Switch.
How to Choose
Budget: All the emulator options (Project 64, Fightcade, RetroArch, OpenEmu) are free. You only need a ROM (which you should own). The only paid option is Smash Ultimate (game + subscription). If you’re on a tight budget, start with S64O or Fightcade.
Use case: For competitive ranked play, S64O is the clear winner. For casual play with a group of friends, Parsec is the easiest. For a general retro gaming netplay client, Fightcade is a good middle ground.
Common trade-offs: The biggest trade-off is between ease of setup and netcode quality. S64O has the best netcode but requires manual ROM placement. Parsec is easy but has higher latency. Also, consider your internet: rollback netcode (S64O, Fightcade) is more forgiving of bad connections than delay-based (RetroArch, OpenEmu).
Frequently Asked Questions
Q: Do I need a legal copy of Smash 64 to play online?
A: Yes, you should own a legitimate copy of the game. You can dump the ROM from your own cartridge using a device like a Retrode or a Wii with Homebrew. Downloading ROMs from the internet is piracy and not recommended.
Q: Can I play with a GameCube controller?
A: Yes, most of these options support GameCube controllers via USB adapters. S64O and Fightcade have built-in controller mapping that recognizes them.
Q: Is there a way to play with 4 players online?
A: Yes, S64O supports up to 4 players in a lobby. Parsec also supports 4 players, but the host’s upload speed will limit quality. Fightcade and RetroArch can also handle 4 players, but it’s more complex to set up.
Q: Why does my game feel laggy?
A: Lag can be caused by your internet connection, the distance to your opponent, or the netcode type. For delay-based netcode (RetroArch, OpenEmu), any latency is added to both players. For rollback (S64O, Fightcade), the game predicts inputs and corrects, which is more responsive. Also, make sure you use a wired Ethernet connection if possible.
Q: Can I play Smash 64 on my phone?
A: Yes, you can use emulators like Mupen64Plus FZ on Android, but online play is not well-supported. There are some experimental netplay options, but they are not recommended for serious play. Stick to PC for the best experience.
Q: What is the difference between S64O and Fightcade?
A: S64O is specifically designed for Smash 64, with a custom netcode and a dedicated community. Fightcade is a general retro gaming client that also supports Smash 64 but with less optimization. S64O is the better choice for Smash 64 specifically.
Bottom Line
For the best online multiplayer experience with Super Smash Bros. 64, use Project 64 Netplay via Smash 64 Online (S64O). It offers rollback netcode, a ranked ladder, and an active community. If you want a simpler, more casual option, use Parsec with friends. Avoid delay-based netcode options if you plan to play competitively.
