Use "the newspaper test". If an article appeared in a local newspaper about the decision and action you made, and your family and friends read the article, would you feel good about it? Here is a video of some ol' man explaining it well - https://www.youtube.com/watch?v=wgvBV6kWE54

If you are really invested, have a conversation with the highest decision making authority you know about what you would like to do and what would be a fair way for you to continue with this? Tell him you are broke and then offer him solutions - buyout the codebase for a token sum? future revenue share? have them invest in you? If the guy/gal is worth his salt this wont be a waste of time.

You would be surprised and what you can get if you just ask.
