RetroConsole brings libretro emulation into Minecraft 1.21.1 (NeoForge). Place a console in your world, build a TV wall from Screen blocks, browse your game library, and play on in-world displays or in a fullscreen viewer.

Early release (0.1.0) — expect rough edges. Feedback welcome on GitHub.

What you get

Retro Console block with a game library UI — tabs per system, search, favorites
Screen blocks that form multiblock TV walls (console must touch the wall)
Fullscreen TV view with volume, quick save/load (F5/F6)
Server-side emulation — video and audio stream to nearby players
Per-player saves, play-time stats, PS2 memory-card sync
In-game config UI — paths, streaming distances, session limits, video presets
Hardware-render cores (PS2, PSP, Dreamcast) via bundled headless OpenGL helper

Requirements


Minecraft	1.21.1
Loader	NeoForge 21.1.x
Java	21
OS	Windows or Linux (64-bit)

macOS is not supported.

This mod does not ship libretro cores, BIOS files, or ROMs. You must supply them yourself and only use content you have the legal right to use.

Quick start

Install the mod JAR into your mods folder.
Launch the game — config/retroconsole/ is created automatically.
Download libretro cores (.dll / .so) from the libretro buildbot → config/retroconsole/cores/
Add ROMs to config/retroconsole/roms/<system>/ (e.g. nes/, gba/, ps2/)
For PS2 / Dreamcast: add BIOS to config/retroconsole/system/ (see wiki/README on GitHub)
Craft blocks (or use the Retro Console creative tab)
Place the console so it touches your screen wall. Right-click → library → Launch.
Right-click again while playing → fullscreen TV view.

TV screens

Screens link only by physical contact with the console.
Same facing/orientation → one rectangular wall.
Look down/up sharply to place floor/ceiling screens.

Tested cores (0.1.0)

Tested on Windows 11. Other libretro cores may work but are not guaranteed.

Core	System
nestopia_libretro	NES
snes9x_libretro	SNES
