So I've been collecting for the 2600 for the past few years, and recently acquired a heavy sixer. The console came with a bonus of several games, including "Laser Blast". A game that I've been trying to get for years, but every time I try, I get out bid. Unfortunately this cartridge does not work. All I get is black screen (sometimes vertical lines), and no sound. This isn't the first time that I've run into a cartridge like this, I had similar issues with a copy of "Donkey Kong", "Venture", and "Fast Food". The difference is that I have working duplicates of those. I know that this isn't a particularly difficult game to get, I've just had some trouble acquiring it.
I've cleaned the contacts with rubbing alcohol, and opened the cart to inspect the board (given the condition of the table, I know that I was not the first to do it), but everything seems fine. I'm guessing that the ROM chip's just bad, but maybe someone a way to resurrect it?
