After loading a cart how do you edit its source code/sprites/sounds?

All toturials say to tap ESC but that doesn't bring up the editors - just a menu.

Oh it seems to be:

ESC
Exit to SPLORE
ESC
ESC

:)

So you finally bought it? Nice.
You can also then save it locally by going back to the command line, navigating to a folder or creating one, then typing save cartname.p8 with whatever cartname you want.

Yeah - thanks! - I tried the sound / music
engine yesterday for the first time :) - got
inspired by an old C64 game:

You can upload carts to any message on the bbs, and they will be playable!

Thanks but I don't yet know now to make
the cart play my music when run. I will
find out soon, though :)

@dfilskov, if you haven't figured out yet how to post a cart in Lexaloffle (this message forum).

First run your program and when you see the screen you want to have for you logo, press F7.

Then exit your program and in immediate mode, type: save @clip

Then anywhere in your message, press CTRL+V. This will paste your program. Save it, and it will appear as a cart you can run.

Oh cool! - thank you. Will that also work
from within the audio editor?

The F7 key will work anywhere, @dfilskov. Even if you are not running code. It takes the current screen whatever it is and makes that the logo.
