Risugami's Modloader

Risugami's Modloader (known as Modloader) is a modloader developed by Risugami during the Beta period of Minecraft (1.0 through to 1.8/1.9). Active development ended at 1.6.2.

Background
ModLoader was the first Minecraft fan made/unofficial modloader created before Forge. FML is, in fact, a cleanroom rewrite of ModLoader, meaning mods from Risugami's modloader were compatible alongside Forge.

Installation
ModLoader and modding around the Beta and early release periods on the old launcher of Minecraft required adding files and folders to the  file and removing the old.

With the 1.6.2 version of ModLoader, the directory needed ML after the id, so instead of the id being "id" = "1.6.2" it would be named "id" = "1.6.2ML" when using the new launcher (directory naming could be anything as long as it matched).

Installation instructions: existing mods and additional information can be found on the original forum thread.

Many of the downloads for the mods are unable normally from this forum thread's current state, so it is recommended for the user to look through the Internet Archive and pasting the link to get possible remaining downloads.

Old Launcher
This only applies to Beta versions and Release 1.0 to 1.5.2

Windows
1.Open %appdata% (accessible via the run window).

2.Browse to .minecraft/bin

3.Open up minecraft.jar with either WINRAR or 7ZIP

4.Drag and drop the necessary files into the jar.

5.Delete META-INF folder in the jar.

mkdir mctmp

cd mctmp

jar xf ~/Library/Application\ Support/minecraft/bin/minecraft.jar

3.Outside of terminal, copy all the files and folders into the mctmp directory. 4.Back inside terminal type

rm META-INF/MOJANG_C.*

jar uf ~/Library/Application\ Support/minecraft/bin/minecraft.jar ./

cd ..

rm -rf mctmp

5.Run Minecraft.

New Launcher
These instructions only apply to the new launcher and 1.6.2 versions of Minecraft

Windows
1.Run latest launcher and download 1.6.2

2.Go to %appdata%/.minecraft/versions

3.Copy the directory named 1.6.2 and paste 1.6.2ML (you may name however you please, but everything must match) so there are now 2 copies.

4.Enter new directory and rename jar and json files to match the directory.

5.Open the JSON file in your preferred Notepad application and change the id from 1.6.2 to 1.6.2ML.

6.Now follow steps 3 from the Windows Old Launcher instructions.

Trivia

 * Modloader and Liteloader are the only modloaders to work alongside Forge. Rift and Fabric notably aren't compatible. And Meddle (known for working on 1.9 to 1.11 snapshots) also isn't due to being only on snapshots compared to other modloaders being on Release versions (besides Fabric). The closest modloader for modern versions that could be considered compatible with Forge is LitLaunch.
