Hello!
I obtained two of these recently from a seller that was also selling some copiers. As you can see from the photos below the adapter is unmarked, and has what seems to be a slot for a Famicom cassette, but the PCB does not have a Famicom connector. I tried it on a Super Famicom. Playing a Super Famicom game works, playing a PAL Super Nintendo game does not work, so it does not circumvent regional lockout. The IC is marked AG B9230 GAL16V8-25LNC.
I have two, so if you want one to figure out what it does, I am happy to give it to you free of charge.
