Yes— Copper is safe to use. Our launcher does not contain any spyware, malware, ransomware, trojans, or neither vibecoded by AI. If you want to check the source code yourself; you can absolutely do that by clicking here.
We do not have our project listed to any other websites or 3rd Party app stores, only download or update copper from our Github Repository. If you find any other sites promoting our project, please let us know in our Discord Server.
We generally suggest users to use popular and good modpacks such as "Pojavly Optimized", "Adrenaline", "Fabulously optimized", "Speed of light", "Simply Optimized forks", "Additive", or "OptiDroid".
We will not provide support to AI generated modpacks, such as:
We don't recommend users to use modpacks from Spunky Insaan, RKMC_GAMERZ & DNA Mobile Gaming, since all of their modpacks are AI generated and/or bloated and filled with misinformation.
Does not work due to missing library for d-rpc, will be fixed in the future.
Not compatible for android and never will be because it is made for PC.
Works only if you have FFMpeg plugin installed. Alternatively you can use Record-able.
Does not work due to imgui & aggressive openGL calls. For alternative you can use Record-able.
Clients like Feather Client (also known as Dawn Client), Fast Client etc. will not work because you can't run a client inside a launcher.
Uses a VMProtected .dll, doesn't properly work even on x86_64 Windows.
Only works if your native OpenGLES driver has GL_EXT_clip_cull_distance extension supported.
Colours might be incorrect and graphical issues may occur with LTW Renderer.
In order to render stuff for the user to see, you need some sort of window. On Android, a "window" is a producer-consumer pair (where the producer is the OpenGL driver that Minecraft runs on).
The "Alternate Surface Renderer" changes who's the consumer.
Off: The consumer is surfaceflinger (the system compositor) which means stricter timings are enforced. This means that stutters practically disappear if your device is good enough.
On: The consumer is a TextureView, which renders the buffer using the standard view system. This is a worse approach, because it reduces the amount of synchronization done when redering, which means stutters for powerful devices. However, less synchronization also means higher FPS numbers.
To fix "Loading Screen Flickering" or "Black Screen" follow the steps below. This fix is only valid if you can hear Minecraft background song & can click on buttons. The red screen & mojang screen flickering, black screen caused by mods will not be fixed with this!
Note: Please Remember that "Force 4x MSAA" will not increase the performance, it just applies Anti-Aliasing which can cause problems with Certain apps such as: Copper, Mojo, Zalith, Amethyst etc.
