If you are trying to run the MASTERPIECE game from THE DREAM TEAM called BATTLE CHESS 4000 and can't bypass the protection just run this small little TSR patch before you run the game! Only 760 bytes... We doubt ANYONE could make it smaller.... Don't get fooled by others, fix yourself own misstakes ! A sticker on the box said:No copyprotection inside game... Hard Core [THE DREAM TEAM 1993] TDT'93 Even better/smaller/more efficient. Absolutely THE BEST
