\"Famicom<\/a>It’s not a myth if it’s true. Yes, Mario, there might be a Famicom to NES adapter in your copy of Gyromite<\/em>. In fact, there might be an adapter in other early NES games, but so far, Gyromite<\/em> is the only game cart I have personally found adapters in. Recently Jake at 8-Bit Joystick was bustin’<\/a> on the well-known NES fan fact that there are NES to Famicom converter boards in some early NES games. Well, I’m here to try to set that straight. For the record, I’ve bought eight copies of Gyromite<\/em> in my life, and two of them had Famicom converters in them (25% rate so far). I’m not going to speculate on the absolute ratio of Famicom to non-Famicom Gyromites<\/em> out there, or even why the adapters are in there in the first place. Instead, here’s a quick guide to show you how to determine if any copy has one of these hidden treasures inside.<\/p>\n

Method #1: Label Variations<\/strong><\/p>\n

\"Gyromite<\/a>I’ve noticed that there is a small difference on the labels of my two copies of Gyromite<\/em> with Famicom adapters in them (henceforth to be called FA Gyromites<\/em>) and the ones without adapters (henceforth to be called regular Gyromites<\/em>). The difference is subtle but noticeable if you can compare the two, or if you have a really good eye for color. Take a look at the picture on the right. Click on it and load the full-sized image. Notice the “Robot Series” logo on the cartridge on the right (the FA Gyromite<\/em> copy has a piece of tape on it so I know which is which). <\/p>\n

\"Gyromite<\/a>The color of the purple in the FA Gyromite<\/em> is a different hue than the regular Gyromite<\/em> on the left. The two FA Gyromites<\/em> I have have less red in the Robot Series color, making for a softer, deeper “grape” color, whereas the regular Gyromites<\/em> have more of a “plum” color to them, with more red in the label. Also, the black background in the regular Gyromites<\/em> is of a lighter, more washed-out looking color than the deeper black in the FA Gyromites<\/em>. Also to the right is an up-close comparison of the two labels. Note the difference in red content in the half-toning pattern and the difference in the surrounding black background.<\/p>\n

I can’t promise that this color difference will hold true for all copies of Gyromite<\/em>, but my two copies of FA Gyromite<\/em> and five copies of regular Gyromite<\/em> all follow the same color differences described above, so I thought I’d mention it.<\/p>\n

Update:<\/strong> Shortly after writing this article, I noticed another difference between FA Gyromite<\/em> and regular Gyromite<\/em> labels. On the label spine where it says Gyromite<\/em> in purple, my FA Gyromites<\/em> have a tiny “TM” trademark symbol after the title. All of my Gyromites<\/em> that don’t have TM symbols are regular Gyromites<\/em>, indicating that they changed the label later in the production run. But this is where it gets slightly complicated: I do have one regular Gyromite<\/em> with a TM symbol, so the TM is not a guaranteed indicator that it’s a FA Gyromite<\/em>. But I’m willing to bet a lot that if it a Gyromite<\/em> cart doesn’t have a TM on the spine, you can rule a FA<\/em> out — it’s a regular Gyromite<\/em>. Further experience will be necessary to make sure this is completely true, but I think it’s almost assured. And before you start complaining that I’m wrong, make sure you’re looking at the label spine<\/strong> (the edge of the cartridge opposite the connector), not the main label face.<\/p>\n

Method #2: Center of Gravity<\/strong><\/p>\n

\"Gyromite<\/a>This is the least scientific test of the bunch, unless you want to go to the trouble of precisely balancing the cart on a specific pivot point. In lieu of such complicated measures, you can use your hand. Pick up a copy of Gyromite<\/em> and hold it in your hand like the picture on the right. If the center of gravity is more towards the middle of the cartridge than toward the connector (and the weight is spread out a little more evenly), then it’s likely that you have a FA Gyromite<\/em> in your hand. You’ll see why in a minute.<\/p>\n

Method #3: Weight<\/strong><\/p>\n

\"Regular<\/a>This test is my favorite of the bunch, because you can quantitatively tell if your Gyromite<\/em> has an adapter without opening it up. If you happen to have a scale that can read in ounces, you’ll find that a regular Gyromite<\/em> cartridge weights about 3.5 ounces, and a FA Gyromite<\/em> weighs about 4.5 ounces. The extra ounce comes from the converter hardware inside, which you’ll see in a minute. I tested my other early NES games and they all weighed 3.5 ounces, telling me they don’t have adapters inside. Also worth noting: I just realized that the pictures of FA game carts (one is Gyromite<\/em>, one is Hogan’s Alley<\/em>) on this page<\/a> and this page<\/a> have full-size DIP<\/a> ROM Chips on the boards instead of glob-tops<\/a> like mine (which you’ll see in a minute). That would definitely make a copy of FA Gyromite<\/em> with DIP chips heavier than 4.5 ounces.<\/p>\n

\"FA<\/a>I also weighed a later NES game (Kirby’s Adventure<\/em>) and found that it weighed about 4.5 ounces as well. Does this mean Kirby’s Adventure<\/em> has an adapter inside? No — it has a bigger board to make room for a battery and likely heftier ROM chips since it’s a bigger game (in KB terms). So keep that in mind if you’re planning on doing a hand weight test in a store. Pick up a copy of Gyromite<\/em> and compare its weight to another early NES game (like Pro-Wrestling<\/em>, but not Zelda<\/em>, which is also heavier because of its battery). If it feels slightly heavier, then you’ve probably got a FA Gyromite<\/em> in your hand.<\/p>\n

Method #4: Open the Cartridge<\/strong><\/p>\n

\"Gyromites<\/a>Unlike Jake<\/a> and Ben Heckendorn<\/a>, I actually have an array of screwdrivers on hand, arranged nicely in a toolbox. \ud83d\ude42 There will be no smashing\/ripping open NES cartridges today. All it takes is a small flat-blade screwdriver to open your Gyromite<\/em> cart. All Gyromite<\/em> carts have at least five screws (unlike the later three-screw NES carts), but if you have a FA Gyromite<\/em>, you’ll be surprised to learn that it actually has seven screws in total! In the picture on the right, I have two copies of Gyromite<\/em> open. The one on the top is the regular Gyromite<\/em>, and the one on the bottom is the FA Gyromite<\/em>. Notice how the adapter\/game assembly is screwed down to two posts inside the cart. Ah-ha — so that’s what whose posts are for! If you unscrew the adapter assembly, you’ll notice that it’s in three pieces. There’s the top board, which is the Famicom board with the ROM data on it, then there’s the 60-pin pass-through connector, and then there’s the bottom adapter board. Here are some more pictures:<\/p>\n

Some Notes on Using Your New Famicom Adapter<\/strong><\/p>\n

I did some simple testing using the FA Gyromite<\/em> ROM board and the adapter itself. First of all, I plugged a Famicom cart, Zippy Race<\/em> into the FA Gyromite<\/em>‘s adapter and tried it in a top-loading NES. It worked perfectly. Then I put the FA Gyromite<\/em> ROM board (the Famicom part only) into a Famicom, and no surprise, it played perfectly as well. It is very important to make sure the board\/cartridges are facing the right way when you use them in a NES. The front of the Famicom cartridge should be facing opposite the front of the adapter (the side with the IC on it). Then, the front of the adapter must be facing either up (on a front-loader), or forward (on a top-loader). Also, you’ll have to flip the 60-pin connector on the adapter around so a Famicom cart will fit on it, and you might even have to trim a bit of the black plastic off the sides so it fits correctly. You might be able to chop off the top of a standard NES cart and screw the adapter into it, as it was in the Gyromite<\/em> cart, so that you don’t have to handle an unprotected PC board all the time and you can use the same adapter with different Famicom games. Also, the mountability of the adapter in an NES cartridge case brings about the possibility of making a permanently converted Famicom game<\/a>. That is, you could disassemble your Famicom cart, take out the ROM board, mount it in a NES cart case (ala FA Gyromite<\/em>), and screw it back up. Then you’ve got a sturdy Famicom game ready to play any time that you want on your regular NES! Whether the adapter works perfectly with later Famicom games is unknown by me. You’ll just have to test that yourself.<\/p>\n","protected":false},"excerpt":{"rendered":"
