Minecraft-320x240-jar !!exclusive!! -

This is an official filename from Mojang. If you found it on a forum or abandonware site, be cautious:

Because this was a modified .jar file containing Mojang’s copyrighted code, it existed in a legal gray area. Distributing the full jar was technically piracy. To get around this, creators released or bytecode patches using tools like MCP (Minecraft Coder Pack). A user would run a .bat script that unpacks their official minecraft.jar , overwrites the resolution class files, and repackages it as minecraft-320x240.jar . minecraft-320x240-jar

Minecraft's User Interface (GUI) scale depends on the screen resolution. At a 320x240 resolution, only a GUI scale of 1 is properly supported. Run-off Screen: This is an official filename from Mojang
