How to setup Minecraft 1.12.2 + Optifine + Forge On a Raspberry Pi 2B, 3B, 3B+ (Untested on Pi 4B)

[timof121]

Hello. Now that i'm on a RPi 4 with 4GB RAM everything works very good. I used RpiMike tutorial for the first part of the tutorial. Thanks!
Do you have any idea about running minecraft custom clients (that are placed in versions, not mods) like Wolfram
Thanks

Not working on Pi4 4GB.
Here is the error when starting the game (not from the launcher):

Code: Select all

Java HotSpot(TM) Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release
Error: Could not find or load main class net.minecraft.launchwrapper.Launch

Hi Tim, sorry I have never done anything with wolfram or custom clients so I have no idea unfortunately.

Hello!
I am making script for Minecraft 1.16.1-Forge 32.0.24~ , but it doesn’t work!
I found some files path was changed, and I debugged.
But I couldn’t find launchwrapper files.
I couldn’t find any launchwrapper files, so it says like script couldn’t load net.minecraft.launchwrapper I think...?
What should I do?

Actually I am using launcher 1.6.93.
It might affect?

Try using this launcher:

Code: Select all

wget https://launcher.mojang.com/v1/objects/eabbff5ff8e21250e33670924a0c5e38f47c840b/launcher.jar

Um.. yeap!
That's launcher seems work fine!
I think net.minecraftwrapper.Launch was changed at nearly Forge versions, and changed to mod.cw????????.
Changing it, that’s work, but Forge spit out STDERR.
Um..., I don’t have any idea hahahaha

Are you crone Minecraft from SD, or is that old versions?
Or maybe Did you try the way what written this forum?

When I tried to crone from SD, that happened too.
Umm... try this!

Code: Select all

java -jar launcher.jar

After Launcher start, click “Play” again.
Some files will download.
After that, you will successfully start Minecraft games!

[ADDed]
If you using more than 1.12 versions, Forge doesn’t use class net.minecraft.launchwrapper.Launch.
Are using 1.12.2?

I have Minecraft 1.8.9 but could you make forge work for this as well?
Please....

[Adamanewtown_on_RPi]

thanks mike for the fast reply will check the link in a moment

[Adamanewtown_on_RPi]

viewtopic.php?f=78&t=284448

half-works, hangs system at the 'joining world' stage then game crashes with no error message

EDIT: I am using a 3b+

[rpiMike]

Which Pi are you using? Running the MC via launcher really required Pi4 2Gb min.

Edit: just saw your edit - time to buy a Pi4 !

[Adamanewtown_on_RPi]

oof - i cant buy one, i only have £10

[Adamanewtown_on_RPi]

i think the optifine is problematic in this case though

[Turtles4Life715]

Please make this work for 1.8.9 there's more mods available
