Can someone help me identify this game?

Hey everyone! This is my first post. I recently started collecting Nes stuff. I was at a flea market this weekend and picked up this Goonies game for 3 bucks. I am aware there was no Goonies 1 for the nes. I know this is a reproduction of some sort but does anyone know who made it or how much its worth? Thanks in Advance!

    Probably only worth $25. If you open it up, 99% chance it just have rewired ROMS on it. Still, great deal for $3 IMO.

    99.9% it's a repro, my question is what flea market did you go to? $3 is dirt cheap, in some cases that's more than the eproms cost lol



    I'm going to be blunt, most folks who say 'I found this at a flea market' are trying to pass off repros as prototypes acquired in the wild. All I can say is don't expect to sell it for more than $20-30 without opening it up. If it is a prototype, you got a hot deal dude. However all signs point to no.

    Might be under 20 if it's someone's old personal gyromite conversion cart. It's either that or a repro. Definitely not a prototype.

    ima go with 100% :-P

    Hey, I like to leave that .01 open for what I like to call 'flea market magic'. I did find a sealed SMB for $3 in NM condition so anything is possible



    Bounce is right too, might be a swap, didn't even think of that.

    @ seestes: Whenever you get the time, and if you can, open 'er up and let us see the insides so we can help identify it a little better.



    Also welcome to NA.

    I payed about $20-25 for my repro, it's a great game and a steal at $3. Enjoy playing. And yeah, open that sucker up for us so we can check it out.

    I've only been collecting a couple months so far. But man, the hunt has been the best part. I dont have the 3.8 mm bit to open it yet. I will order one off of ebay and we will just see what is inside! What is it that I am looking for exactly once inside? I honestly bought this game at a flea market about thirty minutes away from my house. I also went into an old video store today a few miles from my house and picked up a copy of MUSHA for sega genesis for five bucks in the box! I know that is off topic but I was very suprised to see it sitting there among the old games long forgotten.

    Inside you will find a production CNROM circuit board with the ROM chips replaced with EPROMs. EPROM chips are ceramic, and have an erase window in the top. Original mask ROMs are black plastic. There won't be any wiring, since the ROMs in CNROM carts are the same pinout as EPROMs already. Many repro games will have bent out pins and wires running around in them to adapt the EPROMs to the circuit board - and I've seen some *really* cruddy wiring/soldering in some!!



    A gamebit is a must for any collector - even if you do not know anything about electronics, you need to be able to easily open and clean game cartridges and consoles. Get both sizes. The 3.8mm bit opens NES, SNES, N64 and Gameboy cartridges. The 4.5mm bit opens the toploader NES console, SNES console, N64 console, and Sega Genesis cartridges. You'll want that larger gamebit when you find an N64 that someone spilled coke into and got the reset button stuck down. And being able to open cartridges makes them SO much easier to clean the contacts on.

    Could be a Flash EPROM or even an EEPROM just as easily as an EPROM.

    This is true. It is definitely possible, and he won't know without opening it. But very unlikely, especially in this case. An EEPROM (28c256)  would require more work, since the pinout does NOT match the pinout of the existing mask ROM (A14 is in the wrong place). And IIRC, the equivilent Flash ROM (28f256) has the same problem.



    Not to mention that EPROMs are significantly cheaper



    Now, there also exist OTP EPROMs, which are in a plastic package, but electrically the same as conventional EPROMs. Again, they're more expensive, and can't be scavenged from junk equipment (since you cannot erase them).



    I'm going to bet on UV EPROMs.

    Actually flash is much much cheaper than EPROM. And 29F256 should work fine in an EPROMS spot. I have never heard anyone using the 28 series. Seems like they're more expensive than 29F series too.



    I mean, I bet EPROMS too, but still. Could be a chip with the numbers scratched off to make people think it's a sample. Hmmm...that'd be crappy for somebody to try.
