At some point the source code of BubbleGem was published. But BubbleGem drew mercilessly on the screen and blocked multitasking. With the source code (in Pascal) it was easy to reconstruct the functionality in GFA-Basic. Unfortunately GBubble was only a fast hack and that is how the source code looks like. GBubble imitates all functionality of BubbleGem but does not block multitasking. GBubble displays the texts in a window. Hereby the source code of GBubble is made available to the public.
