[Feature request] Implement an equivalent method to Pico 8 Load() about pyxel HOT 5 CLOSED

I just realized something that may help others though. If one clears the screen and properly nulls all the objects, one can call a game from another one as long as:

1. Both share the same dimensions
2. One comments the pyxel.run() from the second game (to avoid calling second instances of EventPump)

It's not as straightforward as the Load() command, but it's a good workaround

Here's a proof of concept of how a launcher could be made with the current codebase. It basically takes the scripts, comments out all calls to pyxel.init() and pyxel.run(), injects code to the update method of the scripts and finally runs it. It can't adapt to different width and heights, it always runs with the default frame rate, and the size of the window and pixels is the default one too.

Everything is very hacky, and probably a re-implementation of pyxel.show() and pyxel.init() could make the task way easier, but at least a solution exist.

Thank you for the prototype. I've also experimented with restarting code in the past when I wanted to do so.

If I were to add an app load feature to Pyxel, I think I would need a method that meets the following conditions:

Works the same in both web and native environments
Supports resolution for each application
Can restart not only the Pyxel code but also other Python modules being used
I haven't found such a method yet, but if I do, I'd like to implement this feature.

Since there is no change in the situation, I will close this issue.

The only way to do this would not be at the Python level, because of all the interpreter state (imported modules, globals…) as well as pyxel state (resolution, palette…), so I can only see using os.execl to execute a clean new process, replacing the current one.

The only thing missing for a pico8-style function would be a way to pass info about the caller, so that the loaded game can provide a way to go back to the original. That could be done with an environment variable for example.
