If you want to publish apps through RetroStore you can contact us, we are happy to add your application to the catalogue. We are also planning to open up our developer portal so you can manage your apps yourself. For this we want to see how many people would be interested to test it. If you are, please let us know at info@retrostore.org
Note: You do not need an account if you want to access RetroStore through one of the clients that use it.
