I'm trying to make an IC2 addon for IndustrialCraft Version 1.115 (Minecraft 1.4.7)
I'm using such an old version as we are still running a very old map on a server, and we don't want to lose the map since it is very complex and we spent many many hours working on it.
I've imported the APIs in Eclipse, and the game loads just fine with just the APIs loaded.
However if I add the IC2 MOD in the FML workspace, the game crashes with this error:
Thanks in advance for your help. I understand this is a very old version
