I'm thinking about buying a SEGA 1L panel and fit on my Xiong Ba cabinet as I never play 2 player games or Robotron anyways.
I don't know how to go about finding a 1L panel though, but.... since Xiong Ba is clearly a knockoff of SEGA cabs, perhaps the panel will fit it.
So, the panel on my Xiong Ba(sheet metal) is 110 mm high and approx 645 mm wide (actually, the metal part is only about 105 mm high, but it needs to be 110 mm to be all snug against the mounting space in the plastic. Is this a close match of SEGA's panels? Like Astro/VS/Blast City and the likes?
Sega (New) Astro City (2), Blast City, (New) Net City, Naomi Uni, (New) Versus City, Megalo 410, Capcom Impress, Konami WIndy (2), Namco Cyberlead are interchangeable sizewise.
Actually, someone once mentioned that Sega panels fit into Egrets (with gaps of course) - so if you test to put in your Xiongaba panel into the Egret, you might see if the bolt holes align
