I think the only keyboard inspired in a real one was mine, inspired on blackwidow from razer.
You will need a picture from you keyboard (I recommend getting it from the official website, the pictures used for showing the keyboard are really good taken), then you will need to get the different kind of keys from that image. So, get any normal key, for example “A”, then “Shift”, “Ctrl”... they are all different sizes, so you need to take them. Then you erase the thing written on it, using Photoshop, so you can use that image to put any letter on it using NohBoard.
You will also need the font used on your keyboard. I personally
made mine from scratch because there was no good one out there.
Then you will have to edit all together on NohBoard. You can use my keyboard as a base, just replacing the images keeping their names...
That version of my keyboard is with a default font because Noh didn’t want to put a custom font inside the folders making the users to install it if they wanted to use my keyboard. But you certainly can set the font to whatever you want if you will use it personally.
