The second article seems actually reasonable. It even links to the first article. What it’s saying is that a Chinese company is butchering the already extremely limited number of working Sega Saturns in existence to resell them for use exclusively with their own brand of flash cart. So they basically remove the CD drive and hook up the cart directly or something.
Well to be more specific, you don’t have to fuck up the console to use the cart itself, which doesn’t seem to be the issue. You can wholly approve of the cart while disapproving of how a certain company is making bad use of them.
