I don't really know but you might need a mod-loader or mabye see tutorials on how to get the pixelmon mod without the mod-loader.So really im not an expert
Yes, to install it you will need modloader, and modloaderMP
i think it comes with one and it comes with forge correct me if i am wrong
Yes. But you need to do this in good way- first instal forge, then modloader. (or modloader-->forge)
Well, you need the game 'minecraft' which does cost money. Pixelmon is just a mod for the game 'Minecraft'.
no, but to get alot of mod you need to have modloader installed on the game.
In minecraft beta, there is creative mod what allows you to get all items.
No. I use that mod and I don't have mod loader.
No I dont think so it depends on what kind of computer.
Lots of mods do not need forge, big ones such as: OptiFine Too many items and Better Sprint (all i know of)
If you've created a new profile for Forge, all you need to do is change to your username in the dropdown list.
I believe you need to install Forge first then run Minecraft once before you install any other mods.
download modloader and drag and drop all the files from the zip into the minecraft.jar using a program like 7zip you will also need to delete the meta.inf folder to avoid having a black screen
