我正好想diy个迷你街机，前两天还发了帖子。楼主方便的话，能否详细说下过程？

我给你提供个成熟方案，不过需要比较高的DIY能力，要有耐心，有决心，有爱。

上面这个是图纸

http://www.koenigs.dk/mame/eng/instructions%201.1.pdf
这个是组装说明

都是英文的不过有爱的话就边学边看吧，我同学按照这个教程装了一个，只不过没用ITX改用树莓派，效果也不错


1 x Lilliput 10.4" LCD monitor
1 x Ultimarc UltraStik 360 joystick
      (UltraStik has build-in encoder)
3 x 24mm orange Sanwa pushbuttons
3 x 24mm black Seimitsu pushbuttons
3 x 10mm pushbuttons

Mini-ITX board - Intel D510MO
1 GB DDR-2 memory
30 GB SSD - OCZ Onyx
PicoPSU
80 mm FAN - Akasa UltraQuiet Amber

再提供一个摇杆连接教程。。。


How do I connect the controls to the dedicated encoder then?
This is actually much easier than most people think. You only need to know some basic things. The encoder has a lot of terminals for connecting your wires. Half of them is for Player One and the other half is for Player Two. Now we have already made it half as complicated

There's four terminals for a joystick, one for each direction, up, down, left and right. The rest of the terminals is for the push buttons. Sometimes there is separate buttons for Start and Coin, but it doesn't really matter how you hook them up because is depends on what function you configure them to in MAME or other emulators / games anyway.

Here is a sample of an encoder, the I-PAC from Ultimarc:


There is also a terminal called GND or ground. There can be one for both player one and two, or just one for sharing. The GND/ground is very important. This terminal has to be connected to every push button and joystick switches. You can just make what's called a daisy-chain, this is a wire going from on push button to the next like a chain or the lighting on a Christmas tree. I made this illustration for making it easier to understand, because I know this GND / Ground thing is what confuses most people and maybe ending up with abandoning the project or, even worse, buying a X-arcade stick . Here goes:






This is of course more simple than a two or four player encoder, but there really is no difference. There is one wire for each push button and one for each joystick direction. The GND / Ground is the same wire just going from one button to another. The order doesn't matter as long as everything is connected to a terminal and the GND / Ground. The encoder is of course connected to the PC via USB or PS/2.

You can connect the wires two ways. Solder them to the push buttons or using crimps like on the picture to the right. Just use what you are comfortable with. The crimps requires some tools, but so does soldering. Using crimps makes it very easy to change defective parts in the future.

Here is some words you might encounter while reading about encoders and wiring:

Crimps: A way of connecting wires to joysticks or push buttons without soldering
Daisy Chain: Often used for connecting your push buttons to the GND / Ground
Ground / GND: Every push button need to be connected to the ground to work
Harness: Ready made wiring or what you call your finished wiring
Micro switch: Commonly used switch used for joystick and push buttons

Sometimes you will encounter micro switches with three legs instead of two. The illustration shows where you need to connect your wiring. It doesn't matter which of the two you use for GND / Ground.






I recommend using different coloured wires for the different joysticks and push buttons and a black wire for the GND / Ground. A 4-player setup will be very confusing of you only use one or two colours.



If you need more information, find it on the different encoder manufactures homepages. I recommend  Ultimarc, home of the I-PAC and MiniPAC that I recommend, but most other encoders are fine too and works just the same.













That's it. - I looks confusing, but it really is very simple.

基本上，先淘宝上找个木工按照图纸把框体做出来（想要上面图片效果就用PVC板材，淘宝上也有），木头的好处就是可以自己喷漆，做做装饰，贴个SEGA标上去之类的（也可以直接用毛坯），然后按照说明书装就行了，过程很好玩。

淘宝上买一对3寸或5寸的立体声喇叭，稍微接个线到ITX机箱上，固定在框体里面，喇叭口位置可以在框体木板上钻几个眼。

多说一句，用树莓派方案更便宜，而且不用风扇，2代树莓派可以完美模拟各种街机，包括ps1. 整个16g的sd卡就行。不过需要一定的GEEK能力。。。
