[2022] How to add your own menu simulation?

I made a reddit post before asking if there was a way to make your own menu simulation. After trying for a couple of hours i don't seem to get it to work.

Here's what i did :

- Because i don't know much about coding i decided to just copy a basic set up (camera zoom, searching for a title etc.).

- I took a copy of an already existing menu simulation and changed the world a little.

However i don't know where to get the level.dat file. I checked similar named files but they were all different. I saw a similar looking file in the blueprints folder but after adding that it still doesn't seem to show up. Does the simulation not show up if it doesn't have a level.dat file? Or is it the coding?

Here's the code i added :

menu_simulations.test ={checkboard = false,save = "__base__/menu-simulations/menu-simulation-test.zip",length = 60 * 12,init =[[    local logo = game.surfaces.nauvis.find_entities_filtered{name = "factorio-logo-11tiles", limit = 1}[1]    game.camera_position = {logo.position.x, logo.position.y+9.75}    game.camera_zoom = 1    game.tick_paused = false    game.surfaces.nauvis.daytime = 0  ]],update =[[  ]]}

Edit : i will try again but with some support of hall of fame mod.

Edit 2 : I DID IT. I MADE A WORKING MENU SIMULATION!
