Chinese nonsense do not read. I rely on myself. My knowledge and intuition.
I found a interessing video about fake chips.

There are fakes but they are obvious like https://www.ebay.com/itm/392188488327
I didn't notice the wider DIP64 package and bought them but when I got around to using them I noticed they where just painted as V9958, if you scratch the top they are revealed to be just M680000P8 CPUs and maybe dead ones from a very quick test I did.
I got one of those too, from a seller that calls himself adeleparts2010. I also bought two AY-3-8910's from the same seller, both are fakes. I got my money back, but they're still selling these fake chips.
What is the problem, if fake chip works properly?
A fake AY-3-8912 let the magic smoke out from my Tiki 100. Luckily it was quite easily repaired, but that was just that, luck.
The video explains how recognize fakes.
Be careful with the fake chips. I bought 6 fake v9958 and it seems like the package of toshiba 68000
Check for yourself:
This is leading to a price dispute. My first v9958 was about 10 usd some months ago... today I got a quote of 111 usd from utsource.
