The two carts look just like the scans of the Shancho games. They both have
"SANCHO tm presents" and then the name of the game. Then below the picture it says "For use with ATARI Video Computer System or SEARS Video Arcade" (in fact the labels on mine look better then the pictures on this site)
I got these two games at a thrift store along with a Panda Space Canyon. It looks like the picture posted for US. I don't know how they could work on my system if they are PAL. Weird.
