u dont need a mod for changing mob spawners, u can just get custom spawners with a command, im not sure what the id's per mob are, but heres the command: /give <username> <amount> <metadata> meta data is the kind of monster spawners what u want, im not sure wich number is wich mob, so u need to find that out for urself , but with the mods too many items or not enough items u can also automatic get the spawners. i also know spawner GUI mod, thats a very easy mod for editing spawners. but i hope this info. will help u
I KNOW there is a mod that lets you place any mob spawner, but I can't remember which one it is. And I have used in my local server, so I know it works in SMP. Maybe NEI? I know that what this mod does is showing in the NEI gui a different spawner for every mob, so you can select the one you want and place it in the world. It even works with mobs from other mods. But I can't remember which mod it was... =(
Yes NEI is the mod that lets you do that i had it for a while and i has all the mob spawners for each mob.
