For much of Minecraft Beta and all of Minecraft Alpha, The Nether was unplayable in multiplayer. It didn't exist there. But this didn't make Alpha 1.2's Nether totally redundant. Some people may not remember that Ghast spawning in Minecraft Alpha was incredibly aggressive. On some days, those Ghasts would spawn in huge amounts.

In this mod, I have patched in something very similar to the mechanic of "Ghast hyperspawning" in versions of Minecraft Beta that normally don't have it. Basically, multiplayer and singleplayer Minecraft Beta will have lots of Ghasts in them all the time if you install this mod. Those players get to experience the horror of overpopulated Ghasts in The Nether.

In Minecraft Alpha, The Nether was very briefly a war zone. In more recent versions than that, The Nether is once again a war zone, thanks to this mod. Expect lots of Ghast screaming and places you're trying to warp-bridge to be blown up over and over, which once upon a time was somewhat normal. This can be used as part of a challenge run, or by people who just want The Nether to be dangerous again.

Plans do exist to possibly make other ports of this mod to Beta 1.8.1 and Release 1.0.0. Though I doubt I'll figure out how to get versions from Minecraft Release 1.2 and later to properly build, that has been trouble.

COMPATIBILITY

This should work with any related base version group of mods, so long as those mods don't edit the original Ghast class.

For extra credit, other mods that have been installed are permitted by design, technically, to edit the variables that decide how frequently Ghasts can spawn.

INSTALLATION

This is important. This mod uses no API, and is just a jar mod were you put the class files inside your vanilla Minecraft Beta .jar file. Modrinth has a feature where you can't select "No API" and must select the "closest" thing to it. You can put ModLoader and ModLoaderMp in here if you really want to, but I can't promise it will help or work.

MultiMC:

1. Download the right SP patch for the version of Minecraft you want.
2. Create a new instance in MultiMC set to the right Minecraft version.
3. Right click on that instance and open the menu "Add to Minecraft.Jar".
4. Select the .zip file you downloaded. Launch the instance now to see if it worked.

Here are the stages for more manually creating a modified Minecraft jar that contains this mod's changes, in case you wanted to now. This doesn't say how to give those properties to a launcher so that the launcher immediately runs it.

1. Get a Minecraft singleplayer jar for the right version.
2. Download the right singleplayer patch from this website. A 1.0.0-SP for the appropriate base version should be fine.
3. Open the Minecraft singleplayer jar in an archive manager and delete the folder called META-INF.
4. Import the .class files from your mod download into that same archive manager, and make sure the files have updated.

Licensing Rights

Ghast Hyperspawning Patch is a very simple mod that anybody could have come up with. By all means look at the code and create derivatives. There's not even that much code in there. Just don't lie about who made this version, and don't reupload this one to some other website, unless of course it's a situation where some extreme losses have occurred and that is the only way to protect this mod from becoming lost media. Making modpacks that have Ghast Hyperspawning Patch in them is totally allowed. I would be happy to see this mod appear in modpacks without any communication needed, though I'd love to hear about cases of this ending up in one if you know how to contact me.
