the contents of the 32X box. the only thing i left out of the pic is the video cable, as some of you may be using an RF unit instead. either will suffice.
here again is the 32X, installed on a Genesis 1. and here is the rear view, showing the cables. REMEMBER: if using the 32X with a Genesis 1, you will REQUIRE the conversion cable (shown in the contents pic, above). this basically converts the 32X connector cable to the larger input on the back of your Genesis 1.
your 32X/Genesis 2 combo should look something like this. you'll have a wealth of cables running from the systems, wall, and your tv. here is the rear view. here is the spacer which should be installed if you are using your 32X with a model 2 Genesis. this helps the 32X to rest flush with the Genesis, and keeps the unit from flexing. here it is fully seated.
a lot of people have been asking what the rf shields ("little metal thingies") are for. they insert into your Genesis in order to cut down on outside interference, or distortion received by the Genesis and 32X units. you DO NOT need to install them. however, i've been told by many people that their reception was improved significantly once the shields were installed. personally, i've never noticed any difference, but it's recommended that you install them if they're available. the larger shield clips in the back, while the small one goes in the front (with the Genesis facing you). here is a pic of both shields in place.
another curious piece included with the 32X is the extension unit. it replaces the plastic slot panel on the rear of your Genesis, and is to be used if you do not have a Sega CD unit attached to the Genesis. here is the piece oriented properly, and here is the extension, fully installed. note: i can't tell you whether or not your Sega CD-less Genesis/32X combo will require the extension unit. i have several Genesis systems, and out of them, one REQUIRES that the unit be attached in order to function. i have been told by most that the piece is not required, and the 32X will run without it. however, if you've got a Sega CD, you're all set and needn't worry about the extension unit in the slightest.
once installed, you usually won't need to remove the 32X. you can leave it in to play both Genesis and 32X cartridges, as well as Sega CD and Sega CD/32X games. unfortunately, you can't use the 32X along with the Power Base Converter, so in that case you would need to remove it. one other thing to note: i have learned that many 32X systems tend to be or become faulty. i own one non-working 32X myself, and after inspecting it thoroughly, have come to no conclusions as to why it does not perform. many people on the ASG newsgroup have complained of faulty or non-working units as well, and a friend of mine once returned 3 units to Toys R Us before receiving a functional system. i don't really have a solution to this, just thought people would want to know.
