Yes, there are grey market pirate converters. However they don't use an official 10NES lockout chip inside and the higher quality Nintendo connectors, shell construction, etc. To get around the lockout they use the same methods the non-Tengen unlicensed NES games use - sending different voltages to the 10NES chip inside the NES. So many of them have "flip the switch on the back to..." or "it is normal for the screen to flash 11 times..." and so forth. These = cheap construction and buggy design.

There's a reason that say, a Wisdom Tree game can take awhile to get going, and a licensed cartridge or an unlicensed Tengen cartridge will start up no problem - that difference is the 10NES chip. (Tengen used an illegal clone they made of the 10NES chip called their "rabbit" chip, works exactly the same though)

I wasn't trying to harsh on your work, it looks very nice.

Technically you own no Famicom games now, instead a FC-NES Goonies conversion. Just like NeoGeo MVS to AES stuff.
