I think if they were really test market prototypes that they would have the printed labels like all the factory conversion chips. Second they would have the name of the game in the menu.
Even if they were in house prototypes they should have the name in the menu and instructions so they know what game they are testing.
I agree with Rory. Looking at the closeups you can see the remnants of the previous chip info sticker. These seem as repurposed chips. If they were proto they would have clean chips not repurposed chips.
