Product Name: 412 In 1 Game Elf (Vertical) + English Jamma store + Power
My son wanted to mod a 1Up Countercade? So we waited for them to drop from $200 to $100 and unfortunately for me? I picked the wrong tutorial to follow? Some guy named Retro Ralph as in Barf. He mislead us with a very convoluted way to mod one of these cabinets? Anyway? Long story short? We wound up using a different tut? With a Rasberry Pi and these pieces here? Are the pieces I ordered due to me blindly trusting Retro Barf's Tut. But? People use these game elfs for the bigger cabinets and an English Jamma is not always easy to find? So I've read in Chinese somewhere? Molex Power Brick that was not included, I had to order that separately too? Then to find out? I did not need any of it? Well that was annoying. Anyway? It's all “like new” store as we never used it. It just sat in my countercade till we finally found a tutorial that made sense.
