I have a ms. pacman

(made in greece), I thinks its bootleg and searching on the web I find that its a Zolapac. The problem is that one of the 27128 eprom has been erased, and shows cubes instead of characters and words ( credit , record) , so I wanna ask you if anyone has this version of pacman, that way I can burn the memory with the exact hex.
Sorry my english, Im from Argentina.
Thanks
