Yes, I know it is outdated, but this is the only way to play the mod I want
I have tried any mod I could get my hands on, and none of them work! I could only get forge in, and when I try to install the coremods, it just gives me a message like this: "[iNFO] File CustomMobSpawner 1.4.3.zip contained no mods
Whenever I add the main mod with the mod_.class file, it just gives me this long message!
"
I honestly have no idea what I am doing wrong, so if ANYONE has any thought to why this is happening, I'd love to know.
(Forgot to mention I tried doing this on another computer, still didn't work)
