Does anyone know anything about these adapters? NES to Famicom

Sorry about the link for mobile eBay but I am not at my computer right now

They're being sold by someone in Hong Kong, I need it to play NES games on my Famicom AV was wondering if anyone had experience with the ones sold by this seller.

I actually just bought one to replace the one I was using, mainly because this is one of the few that has the NES cart facing forward. Not sure what the compatibility is like but I'll find out soon enough.

Alright, mine came in today (very surprising considering it came all the way from Hong Kong) and though I haven't tried much, I can confirm that Castlevania III is not compatible with this one. Should be easy enough to fix though. I also noticed it has holes for screw posts, which is strange considering there's no case with it.

EDIT: I just noticed that this is actually the exact same converter as this one minus the case (really hate to use one of Drakon's images though):

Oh the one I discussed modding with you. From my experience Fester's Quest didn't work either.
