Abstract

We introduce Voyager, the first LLM-powered embodied lifelong learning agent in Minecraft that continuously explores the world, acquires diverse skills, and makes novel discoveries without human intervention. Voyager consists of three key components: 1) an automatic curriculum that maximizes exploration, 2) an ever-growing skill library of executable code for storing and retrieving complex behaviors, and 3) a new iterative prompting mechanism that incorporates environment feedback, execution errors, and self-verification for program improvement. Voyager interacts with GPT-4 via blackbox queries, which bypasses the need for model parameter fine-tuning. The skills developed by Voyager are temporally extended, interpretable, and compositional, which compounds the agent's abilities rapidly and alleviates catastrophic forgetting. Empirically, Voyager shows strong in-context lifelong learning capability and exhibits exceptional proficiency in playing Minecraft. It obtains 3.3x more unique items, travels 2.3x longer distances, and unlocks key tech tree milestones up to 15.3x faster than prior SOTA. Voyager is able to utilize the learned skill library in a new Minecraft world to solve novel tasks from scratch, while other techniques struggle to generalize.

Voyager discovers new Minecraft items and skills continually by self-driven exploration, significantly outperforming the baselines.

Introduction

Building generally capable embodied agents that continuously explore, plan, and develop new skills in open-ended worlds is a grand challenge for the AI community. Classical approaches employ reinforcement learning (RL) and imitation learning that operate on primitive actions, which could be challenging for systematic exploration, interpretability, and generalization. Recent advances in large language model (LLM) based agents harness the world knowledge encapsulated in pre-trained LLMs to generate consistent action plans or executable policies. They are applied to embodied tasks like games and robotics, as well as NLP tasks without embodiment. However, these agents are not lifelong learners that can progressively acquire, update, accumulate, and transfer knowledge over extended time spans.

Let us consider Minecraft as an example. Unlike most other games studied in AI, Minecraft does not impose a predefined end goal or a fixed storyline but rather provides a unique playground with endless possibilities. An effective lifelong learning agent should have similar capabilities as human players: (1) propose suitable tasks based on its current skill level and world state, e.g., learn to harvest sand and cactus before iron if it finds itself in a desert rather than a forest; (2) refine skills based on environment feedback and commit mastered skills to memory for future reuse in similar situations (e.g. fighting zombies is similar to fighting spiders); (3) continually explore the world and seek out new tasks in a self-driven manner.

The PSP’s UMD drive is slow. The fix requires that eliminate the "gray void" effect where roads fail to load.

Over time, Rockstar ported LCS to other platforms. Each port attempted to recapture the magic but introduced new flaws. The question driving this paper is:

Boot the game, open your CFW recovery menu, and ensure your CPU clock speed is set to 333/166 for peak performance. The Ultimate Handheld Nostalgia Trip

The Seen in Liberty City mod is distributed as an , making it universally accessible across the entire PlayStation family ecosystem. Supported Platforms:

It includes custom music, radio stations (including the original PS2 soundtrack), and artwork. Key Features of the Fixed Port

For years, searching "gta 3 psp port fixed" led to dead links, Russian mod forums with broken instructions, and YouTube videos promising a "100% working ISO" that were actually just Liberty City Stories in disguise.

Unlike earlier, buggy homebrew attempts, the "Fixed" versions offer:

To appreciate the "fixed" state of the port, it is important to understand why it failed in the past. Early homebrew iterations tried to force-feed PC or PS2 assets directly into the PSP's limited memory. The PSP only has 32MB of RAM (64MB on later models like the PSP-2000, 3000, and Go), which immediately caused memory overflow crashes. Gamers faced invisible walls, missing textures, absent radio stations, and constant lag.

The original PSP had limited RAM (32MB on earlier models, 64MB on PSP-2000/3000). The community project optimized how assets are loaded, preventing the dreaded "crash-to-XMB" when spawning vehicles.

To understand why the "fixed" port is such a milestone, we have to look at how the port came to be. The project relies on , a groundbreaking, open-source reverse-engineered version of the GTA 3 source code.

Utilizing the PSP’s graphical processor better, allowing for higher, more stable frame rates (targeting 30 FPS, though often variable).
