There was a reddit post about a month ago where several people found some re-sellers on shopee. So there are obviously still people selling these. I'm sure most people understand the context of these chips. That won't prevent people from seeking them out. As far as possibly being Nintendo, yeah lol I'm definitely nintendo.
I searched around everywhere for weeks, finally found an SX Lite switch, spent days researching/setting everything up... and then found the screen to be too small for detailed games lmao RIP. Back on the hunt again for a V2.
They are out there, you just gotta turn over every stone. The ones you can find on alibaba/taobao are all crazy expensive now. Close to $200 for just the chip.
