A. The newer Vewlix and Namco cabs that are made now are all in some form of HD.
Cards like the one you linked to is for cheap Arcade owners/operators to install older arcade boards into newer cabs.
Cards like these are so Arcade owners can cheap out on repairs and use a standard Flat Screen PC monitor instead of getting the better made and more expensive flat screen options that are actually built with arcade cabinets in mind
Still Most Arcade cabs have the video systems completely separate from the sound.
Some Cabs don’t even have audio amps, as they expect the the Arcade boards to have their own audio amp.
Hence why so many SuperGun users use resistors to bring the attenuate the audio back down to line level so they don’t accidentally blow their speakers or sound systems.
Like what The Phantomnaut said, it looks to be a GBS-8200 variant or something along those lines. Yes the Device works, I never said it woudn’t work. but you be getting what you pay for, which isn’t much.
B. And Older Arcade boards only output at 240p. You get no benefit of forcing 240p content to upscale at 4k. Also if you go the cheap route it can look and feel like ass.
Only reason to force something to 4K is to match the native resolution of the Display, as HDTVs often have shit scalers that adds lag to the video.
C. Well we might not know for sure, but based on past experiences with every other $50 HDMI video scaler on the market I can make pretty educated guess how this is all going to go down.
If you want to take the plunge and spend $50 on a sub par solution, go for it. It’s your money. But if you want the best advice out there, I would take a pass.
Also the eBay seller you link to only has a 98.7% Positive feedback rating, that is actually terrible feedback for a seller.
154 Negative feedbacks in a month, 709 in the last 6 months and 1729 in the last year. That is a ton of unhappy customers.
If you have to buy this board, buy it from a seller with a better reputation, Minimum 99%, preferably 99.5% or better.
