Mo Creatures And More Creeps And Wierdos are not compatible and you have to se if all the other ones are compatible either. Then if the other ones are you would need modloader, audiomod, and maybe forge.
ive tried doing only mo creatures, i used modloader, forge, GUI, customspawner, and mo creatures. i put them all in the jar file except customspawner and mo creatures, and i made a mod folder in the bin and put them in it.it didnt work. anyone know what i did wrong?
