Alright, I managed to make the console work. I'd upload the files, but I haven't posted three times yet. First, you're going to have to replace your 00console.rpy file, and maybe its .rypc file, in your renpy/common folder. I replaced them both anyways to make sure. If you keep them as it is, even if you managed to mkae it so you can call the console in game, you wouldn't see anything. Make sure you enter the new 00console.rpy file to ensure that config.console is True. Next, you're going to need to edit your 00keymap.rpy file. CTRL+F to find "console = _invoke_game_menu," you're going to want to replace that with "console = _console.enter,". After that, you can go into your 00start.rpy and directly delete lines 299 and 300. If you do so, you can access the main menu when the game starts up.
There you go. Shift + O should open the console, and you can use ESC to access the menu.
