The developers were required to remove the BASIC interpreter before Apple would approve the application; however, they apparently included the ability to remotely enable the interpreter in hopes that Apple would change their mind...
Unfortunately Apple this night pulled the C64 App from the App Store. We had agreed with Apple to remove basic from the application, but as we believed it would be possible to convince Apple to let it in later on, we left it in the app to be activated remotely by us when we had go from Apple.
Due to the extreme publicity the app has received over the weekend and the fact that several users found a way to enable the basic back, Apple decided to remove the app from App Store until we have solved the issue.
This is very frustrating as we had no intention of tricking basic into the app and the fix was done in a few minutes the moment we found out - a new version has been submitted to Apple, and we can only hope Apple will appreciate our efforts to apply the changes they need in order to put it back on.
