env.load_rom("game.nes", rom_data)

# Step through frames
obs = env.step(0)  # 0 = no button pressed

import gymnasium as gym
import tetanes_py

env = gym.make("ExampleGame-v0", rom_path="game.nes")
obs, info = env.reset()

for _ in range(1000):
    action = env.action_space.sample()
    obs, reward, terminated, truncated, info = env.step(action)
    if terminated or truncated:
        obs, info = env.reset()
