I am relatively new to modding, and I've able to install mods with little to no difficulty on versions like 1.12.2 and 1.7.10. However, I have encountered a puzzling issue regarding 1.2.5.
I'll first state everything that I have done so far:
- I've downloaded the client for Forge 1.2.5
- I've deleted the META-INF file located inside the minecraft 1.2.5 jar file
- I've copied the contents of the Forge 1.2.5 client (along with ModLoader and ModLoaderMP) directly into the 1.2.5 jar with winRAR
- I've put the rar file for the mod I wish to use in the mods folder
When I open minecraft 1.2.5, the loading screen will stop at "unpacking .....9.0-natives-windows.jar" with 0MB remaining. The game will then crash upon launch.
If I run the game with META-INF not deleted, the game will stay at mojang logo indefinitely.
Note that I am able to play Minecraft 1.2.5 otherwise.
If you know how to fix this, please tell me. If I should go somewhere else to get help for this, please tell me as well.
