Hi again everybody. I was lurking around this forum for far too long. Now it really got me, and I decided to start, building my own first 'arcade' machine. I put the word arcade in quotes, because it wont play any real arcade titles, but original GameBoy Games instead.
This project primarily serves as an exercise for me, for getting to know all the important stuff, when building an arcade – or at least some of it.
As for the design of the build, basically I am using someone elses. I really can not remember from where I got it, since I basically collected and downloaded all the stuff, which looked interesting to me for a few weeks and I didn't put it all in my browser favorites. For all I know, it could be from this forum. Someone was kind enough, to post plans of his design.

So, ok. Here is the first picture I did in foddoschobb. Since then I already did many changes. Probably gonna have to update this sketch.
Basically, inside this thing will be an SNES, halfway disassembled. I will take the upper half off of it, so that it fits better inside (less space). Then there will be a Super GameBoy adapter being inserted into it's slot, so that the upper half sticks out of the controls board. At first I was thinking to use one of those really sweet 'Super GameBoy Commander' joypads. They were never sold in europe, as far as I know, but you can buy them for a relatively good price in ebay, and have em shipped from japan. I would have had kind of a mold, so that you could have placed the controller inside that mold, after you where finished playing.
But, although I like that controller a lot and it really gives you a throwback to those original classic GameBoy controls, somehow the arcade machine didn't seem 'arcady' enough without a real joystick and some buttons. So I decided to scrap the part with the 'Commander joypad' and implement a real arcade joystick and buttons instead. I will have a disassembled super NES controller inside, which will be be soldered (solded?) to the arcade controls. Shouldnt be too hard I think. In addition, I would solder a power switch for on/off, so that you can actually switch the power on or off on the super nintendo.
I am planing to use a 19” TFT screen, which sits right there in the middle. In front of the TFT there will be a plate of acrylic glass ('Plexiglas' in german) on which I am going to place a sticker, so that you have the typical 'Dot Matrix with stereo sound' – stuff and so on, around the screen itself. I am also planning to use a small light indicator for the 'battery' thingy on the left side, so that when you switch the thing on, it also lights up. Just like as if you where using some AAA batteries with it and it shows you how much power you still have.
Of course, when you want to switch to another game, you would physically change it for another gameboy catridge and there you go. I know there are probably enough site where you could get ripped roms and stuff, but I like that idea of retaining some of that originality, by using the real original catridges. I have a nice gameboy collection of my own and I guess I wouldnt be the only one, thinking this way.
As for the side art, I came up with something already much better, than that filler 'gameboy' headline I used in that first sketch there. The best thing is, that my partner is very much a pro, when it comes to artistical stuff. He is kind of wizard with airbrush and nearly everything else, when it comes to painting and so on. So I did this in fodooschobb:

My main goal here was, to stay as faithfully to the original packaging, we had here in europe, when the GB came out. Then I added some of the most iconic figures from several gameboy games and there you go. Of course the screen of the gameboy there will not be showing tetris. Maybe it will just show the 'nintendo' logo, or it will be just blank, I dont know yet for sure. So my partner said, that he can do that, using airbrush. I am pretty excited how something like that would turn out, when done with an airbrush.
Regarding the marquee, I was planning to use a sticker I can put on a piece of acrylic glas. Behind it, I would put some kind of blueish light and leave a little bit of space around the letters of 'GameBoy', so that it could shine through there. Maybe make it more diffuse, so that you are not blinded by the glare or something.
