Sadly core modding is still a thing.

and it feels like core modding is something bad. What are core mods? Are they bad?

 

Edit: Nevermind. I found a post with information on it. http://www.minecraftforge.net/forum/topic/62870-what-is-a-coremod-and-what-are-it-advantages-and-disadvantages/

 

I don't know how to delete my post. Although I still wonder if there is a way to identify which mod out there is a coremod.

Thanks!

 

I sort of found that thread a few seconds ago and edited my main post. Would there be a way to identify coremods in places where one downloads mods to play?

I see.

Its not that difficult to do, if you open the JAR file as a zip and find the MANIFEST.MF file (inside the META-INF folder) and open it in a text editor, if it has the FMLCorePlugin value set, then it's a coremod (more accurately: if it is not set, it cannot be a coremod, if it is, you would have to examine the indicated class in JD-GUI to look for the annotations* that declare the class for being loaded for the class transformation events--ie. coremodding--but the only reason that it would be set would be if the developer went out of their way to set it because they need to perform those operations).

 

*Deliberately vague.
