I got into retro arcades just a few months ago. This was my first serious mod. I know nothing about electronics at all. But the 51-minute tutorial breaks it down step-by-step so even a fool like me can do it. These guys are the real deal. I will definitely buy from them again.
The kit itself is amazing, it comes with all the screws, and even jigs for where you cut things. Incredibly thorough.
The buttons and joystick it comes with are great quality too.
I have one small but important complaint: the kit comes with everything you need EXCEPT a power cord. I know you guys sell them, so just add one to this kit and raise the price $4. Or at least let us know we'll need to add one to our shopping cart the way you let us know we need to by the LCD driver separately. When I realized there was no power cord included, I went to Best Buy and Home Depot and neither sells them. I had to order one online.
Also, the video is very thorough but it doesn't show how to replace the LCD driver, and I needed to see that. I know there's a video about how to flip up that little plastic piece, but I am a fool and had no idea that all I had to do was slide the ribbon in there, close that piece, connect it with the white cord to that other piece, and mount it with the tape (which is a great touch) and I'd be done; I had to go down a YouTube rabbit hole to find a video of someone replacing their LCD. If you add that one piece of explanation to the tutorial, there's nothing missing at all.
I am still shocked I got it to work. If I can do it, anyone can.
I modded mine into a Donkey Kong, and used my original control panel (it was a Frogger). I drilled the On/Off and Sound switches into full button holes because there was nowhere else to put the buttons that would fit.
Since we end up with no volume control, the only way to change the volume is with the Test button, or turning the dipswitch 4 on inside the machine, both of which require opening the back. But I came up with a cool workaround: the Test button is exactly the size of the hole that the original power cord came out through the back from, so I mounted it back there (see the second pic below) and now I can get into the Dipswitch settings whenever I want without opening the machine. I didn't have to drill at all.
