It's not the fact that you are a girl that I noticed first, it was the proper spelling and grammer.
Okay, the Genesis shouldn't be that hard. Most people use a clone or a Genesis 3 or a clone, but it would be interesting to see one using a Genesis 1 or 2. Those are huge though, so your best bet is the Genesis 3. You will also need a screen, lots to choose from. Most people use the PSone screen, which is 5" and takes composite and RGB. It's nice but I can't find any locally, and none cheap online. Really, any screen that takes composite in will work; I'm using an Intec Wii screen for my YAP64/2. You will also need a case. There are a lot of options. You can buy a premade case from Polycase or another company; some people call these uncreative but they are relatively cheap, work great, and can look good with not a lot of effort. There's frankencasing, where you glue and Bondo things together into a case; usually it starts with something resembling a case. Vacuforming is a great technique, you can get any shape you want (within reason), and it makes a nice case. Unfortunately you have to build a vacuum table and it can be cheap or expensive depending on how good you are at salvaging things. Lastly, you can build a case from plastic or other materials. Usually acrylic (Perspex or Plexiglass) is used because it is relatively thin, relatively strong and easy to glue and paint. Wood can look nice but is difficult to use and requires a lot of skill to do right. You will probably also want batteries; Li-Ion or LiPo ones have become the standard- we used to use Ni-XX or even alkaline cells but Lithium ones are a lot better.
Of course, you will need some tools. A soldering iron for sure, get a 30W or so electronics one. I wouldn't recommend a cheap one, I have a Weller WP25 and it's a lot better. But if you are just starting out and not sure, or on a budget, it's only $9 or so into the trash when it breaks (and it will, one way or another). You will also need solder (of course), and a desoldering tool. I use a desolder pump and it works great. Some people buy a desoldering iron or solder braid. I can't say about the iron but the braid doesn't work for me. Apart from those tools you will need wire strippers (the cheap kind is fine, you don't need auto adjustment or a lot of little holes), small needle-nose pliers, and some screwdrivers. For casemaking you will need at least an x-acto knife, hacksaw (smaller is better), files (mini ones are essential), and sandpaper. A Dremel tool, drill and bits are useful as well. Some people use bandsaws and drill presses but it's not necessary.
Confused enough! Great! Oh, and welcome to ModRetro!
just kidding.
I'm sure I can figure it out.
