Juni Emu
by JuniperBear
Juni Emu lets players run Game Boy Advance games inside Minecraft, using a GBA emulator built on the libretro gpSP core.
What it does
Juni Emu is a Forge mod in the Minigame category that runs the emulation process within Minecraft itself. The emulator is ported into the game and shown on an in-game display, with GUI elements meant to make it feel like part of the game. Starting with GBA, the planned series of emulator mods is intended to grow over time.
Game cases and cartridges are the mod's central items. Game cases turn up inside abandoned game stores around the Minecraft world. Each case gives a cartridge with a random legally obtained ROM taken from the roms folder that the mod creates in the instance's .minecraft folder on first load. Saves work through the cartridges: two cartridges of the same game keep separate saves, and saves can be synced and shared with others on a server.
Juni Emu needs Forge and is published for 1.20.1 – 1.20.6 in six release versions. The server and every player need the mod installed. The mod is distributed under All rights reserved and is not open source. The author describes multiplayer support as still in progress: GBA Wireless adapter emulation is incomplete, and play over a local network has worked while play over the Internet has not yet been tested.
