Replay Mod NeoForge compatibility is one of the most searched questions among modern modpack players. The short version: the original project documents Fabric for Minecraft 1.14 and newer, and NeoForge players currently depend on community ports that are maintained separately from the original developers.
What the Original Project Supports
The official documentation lists Fabric for Minecraft 1.14 and above and Minecraft Forge for 1.12.2 and below. NeoForge, which split from Forge in recent years, is not part of that official list. Any NeoForge support therefore comes from other developers building on the open-source code.
- Fabric covers modern versions in the original project.
- Forge covers legacy versions in the original project.
- NeoForge relies on unofficial ports.
- The GPL license is what makes those ports possible.
Community Ports for NeoForge
Several projects bring Replay Mod features to NeoForge. ReForgedPlay, by Ferri_Arnus, describes itself as an unofficial port to NeoForge and Forge. NeoReplayMod is another port that focuses on restoring core features such as recording, camera control and rendering, and its page warns that missing features and bugs are possible.
| Project | Type | Maintainer notes |
|---|---|---|
| Original Replay Mod | Official | Fabric for modern versions |
| ReForgedPlay | Unofficial port | NeoForge and Forge, separate support |
| NeoReplayMod | Unofficial port | Work in progress per its own page |
Add-ons built around ports
Some add-ons target these ports directly, such as patches for specific combat or voice chat mods. Those add-ons usually name the exact port and version they require, so read their requirements carefully.
Using Fabric Mods Through Sinytra Connector
Sinytra Connector is a compatibility layer that lets some Fabric mods run on NeoForge. A few replay-related projects mention working through it. Results vary by mod and version, and Connector adds another layer that can affect stability in large packs.
Use this route only after testing in a copy of your modpack. If something breaks, removing Connector and the Fabric mod should return the pack to its previous state.
How to Test a Port Safely
Unofficial ports are useful, yet they deserve a cautious approach, especially in packs with valuable worlds. A short checklist keeps the risk low.
- Duplicate your modpack instance before adding anything.
- Back up the worlds you plan to record.
- Record a short session and play it back fully.
- Render a few seconds with FFmpeg installed.
- Read the port's known-issues list before long sessions.
Where to Ask for Help
Problems in a port belong with that port's maintainers. Projects like ReForgedPlay Fix explicitly ask users not to request support for fork-specific changes from the original Replay Mod or ReForgedPlay maintainers. Following that lineage keeps reports in the right place.
Include your NeoForge version, Minecraft version, the port's version and your full mod list. Logs from the logs folder help maintainers reproduce crashes quickly.
Choosing Between a Port and Fabric
Some players run a separate Fabric profile purely for recording, using the original Replay Mod with the same Minecraft version. This works well for vanilla-style content. Modded content that only exists on NeoForge, however, needs a port to be recorded inside that pack.
Decide based on what you need to capture: vanilla builds and servers suit Fabric, while NeoForge-only mods and machines require a NeoForge port.
Comparing Your Options
Each route has strengths and trade-offs. Seeing them together makes the choice clearer for your project.
| Option | Best for | Main trade-off |
|---|---|---|
| Fabric profile with original mod | Vanilla-style worlds and servers | Cannot load NeoForge-only mods |
| NeoForge community port | Recording NeoForge modpacks | Unofficial, support varies |
| Sinytra Connector route | Experimenting with Fabric mods | Extra layer, mixed results |
Keeping Recordings Compatible
Replay files are tied to the setup that recorded them. Opening a NeoForge recording usually requires the same modpack and port that captured it, because the replay contains modded content.
Archiving the full instance alongside important recordings preserves the ability to reopen them. Note the NeoForge version, port version and modpack version in a simple text file inside the archive.
- Store recordings with the instance that created them.
- Avoid updating the port mid-project.
- Test playback after any modpack update.
Signs a Port Is Well Maintained
Not every port receives the same level of care. A few signals help you judge whether a project is suitable for regular use or better kept for experiments.
- Recent updates for current NeoForge versions.
- A clear list of known issues and missing features.
- A public source repository or issue tracker.
- Credits and links to the original Replay Mod project.
Rendering on NeoForge Ports
Ports that keep rendering support still rely on FFmpeg. ReForgedPlay's own page notes that FFmpeg is required, and installation follows the same pattern as the original mod, with FFmpeg placed inside the instance folder on Windows.
Render a short clip after installing a port. Rendering touches more systems than simple playback, so it is the best quick test of whether a port works well in your pack.
Staying Informed
Loader support changes over time as projects evolve. Checking the original project's pages and the port's pages before starting a big project ensures your plan matches what is currently available.
Questions to Ask Before Choosing
A few simple questions point to the right route for your project. Answering them honestly prevents hours of troubleshooting later.
- Does the content you want to record exist only in NeoForge mods?
- Is the world or modpack valuable enough to need extra backups?
- Does the port support your exact Minecraft and NeoForge versions?
- Is rendering required, or only playback for review?
When the answers point to vanilla content, a Fabric profile is simpler. When they point to NeoForge-only content, a well-maintained port is the practical choice, tested carefully in a copied instance first. Revisiting these questions at the start of each new project keeps your setup choices deliberate rather than habitual.
Conclusion
Replay Mod NeoForge support exists today through unofficial community ports rather than the original project. Test ports in a copied instance, back up important worlds and send bug reports to the correct maintainers.
For vanilla-style recording, a dedicated Fabric profile with the original mod remains the most direct option.
