I really appreciate your effort and time.   As for the Burger Time, I remember I was trying to get the burgers right but since I don't understand the flow of the program I could only play with the TIA registers...   this is the NTSC version if I am not mistaken:   this is the same code on PAL60   and this is my hack on PAL60 - the pink bottom of burgers has to be done if possible but I don't know how...
