Because MCPAtcher is used for texture packs, what you want is Modloader or another program.
Mo'Creatures don't need McPatcher, but Minecraft HD does. McPatcher is actually easier to install mods and HD texture packs so "yes" to your question.
Minecraft Forge lists you all mods in minecraft and Forge
Optifine is another but not too many texture packs and mods are compatible with it. It just depends on what you use.
Either use one of the "mod loaders" like MCPatcher, ModLoader, etc, to load the mod for you or follow the instructions of the mod maker. Some are different on how they are supposed to be installed or what other mods they are compatible with.
You must not have installed the mods correctly
It is quite possible that your are installing the mods incorrectly or attempting to install incompatible mods To avoid this use a mod installer (like MCPatcher) and install Forge Mod Loader first so all your mods work together
The Vanilla version of Minecraft refers to the game with no mods or texture packs installed.
it crashes, memory overload
Use MCPatcher, it can install any mod and it works well Also, make sure you have the right version of the mod for your version of Minecraft
no, but to get alot of mod you need to have modloader installed on the game.
you can get minecraft mods and textures off the minecraft mods website.
Go to Youtube and search for Minecraft mods. There are just too many and some are installed differently then others.
