hi, i recently found this game with other games, it is made by ACTIVISION, below is the info.
WHITE STICKER IN MIDDLE OF CARTRIDGE, THERE IS TWO SCREWS, ONE OF EACH SIDE OF STICKER
sticker read the following
THIS IS A EPROM SAMPLE. TO BE
RETURNED TO ACTIVISION UPON

problem is i do not have a 2600 PAL system, i do not know what this game is or what the possible value. so any help would be appreciated, thanks a lot.
