This mod will stop Forge mods from loading - it does not allow Forge and Fabric mods to be used together!
Make sure you back up before you join worlds where you have used Forge mods previously - as all the blocks/items added by those mods will disappear.
Jumploader
Jumploader is a mod that allows the use of Fabric mods in Twitch modpacks, by loading Fabric as if it were a Forge mod. It works on both the client and server, however it's only necessary on the server if you want to launch the game using tools that only support Forge. Jumploader is fully configurable to load any Minecraft version and mod loader, but by default it will load the Fabric loader and library versions corresponding to your current version of the game. It only loads if your game was launched from Forge/ModLauncher, so it won't do anything if your Minecraft launcher already supports Fabric.
What it does
- Loads Fabric (or a different configured mod loader) instead of Forge, from a Forge installation.
- Automatically loads the latest Fabric loader version for your version of the game, with no required configuration.
- If necessary, loads the unpatched Minecraft game, so that Fabric can be used with it.
- Ensures that Fabric and Mixin don't see the classes loaded by ModLauncher.
What it doesn't do
- Jumploader doesn't let you run Fabric mods with Forge or Forge mods with Fabric - it hijacks the launching process so that Forge never loads. See Patchwork for a project aiming to let you use Forge mods with Fabric.
- Jumploader doesn't currently work very well on the client for loading a Minecraft game with a different major version (including snapshots) to the currently loaded game, as supplementary assets (such as sounds) are downloaded separately by the game launcher. The Asset Validator mod fixes this issue.
Requirements
Requires a Forge version that uses ModLauncher (or ModLauncher on it's own, without Forge) - this usually means 1.13 or newer.

I'm comp500#7396 on The Fabric Project Discord server. I'm also /u/comp500 on reddit and comp500 on Keybase. DM me or @ me at any time if you have any questions!
i cant really find out a way to install the patch and i dont know where to ask but how are you suppose apply the patch?
In reply to medic_is_god:
What do you mean by patch? This is a mod, that you use in the CurseForge launcher. If you aren't using the CurseForge launcher this mod will not be necessary.
In reply to comp500:
i ment pachwork
"Jumploader doesn't let you run Fabric mods in tandem with Forge mods - it hijacks the launching process so that Forge never loads. See Patchwork for a project aiming to do this"
and now that i am reading this for about the 10th time is patchwork wanting to stop the hijack or is aiming to hijack
In reply to medic_is_god:
No, it's aiming to let you use Forge mods with Fabric, heh. It isn't in a usable state, though, so you won't actually be able to use it for a while.
How do I uninstall it, I have an older version and when I load my huge 335 forge modpack minecraft crashes. I HATE THIS MOD
In reply to bcrb1x:
Just remove the mod from your mods folder.
I can't use the Jumploader because it gives me this message "Failed to download jar: Authentication token is invalid, please go online to download the Minecraft JAR!" whenever i wanted to launch the game (newcomer to forge btw). How do i fix that?
In reply to SkyQuartzGD:
If you bought the game in the last couple months, it won't work as Microsoft accounts aren't supported yet. I'm working on a solution to this.
You are a legend. Thank you!
Maybe it's better to have the warning here larger than this, so people will notice it better.
In reply to Qboi123:
Possibly, the text is sort of eye catching enough but maybe an icon could be used like many other Fabric mods do. Like the Fabric logo, a banner or so that states it more clearly.
Either way it could work but just like how on the Fabric API curseforge page (with questions like: "is this for Forge", "is there a 1.12.2 version" and more appearing every so often), people just don't understand still.
And no wiki entries typed up or Youtube videos by fairly big and smaller Youtubers will change it compared to Forge's presence and people still not getting two modloaders always being a thing throughout Minecraft's entire fan modding existence.
Only those that use Fabric or used Liteloader or Rift really get what's going on after all.
Either way a good logo/icon I think would work better or good alongside larger text, but larger text is still a good solution.
When is the update for 1.16.5 coming?
In reply to theprogrammer7:
Jumploader doesn't need to be updated to new Minecraft versions, I'll mark it as available for 1.16.5 now.
Does this also use the Fabric/Yarn mappings? I'm worried the different mappings being used could cause hard to diagnose issues.
In reply to chexo3:
This mod just launches Fabric loader, and Fabric loader will use the intermediary mappings (Yarn in a development environment). As stated in the description, Jumploader doesn't let you run Fabric mods with Forge mods - your Fabric mods will require Fabric intermediary anyway, so there's no difference from a normal Fabric loader environment.
I'm confused, I tried loading in my game and the only mods that worked were the fabric mods but not the forge mods. Is that suppose to happen?

In reply to lightwar2:
this mod stops forge loading and instead loads fabric only, its for if you want to make a fabric modpack with twitch as the launcher doesn't support this natively
