Hey all, I decided to join this forum to see if there was any info on these carts. I got both of them on ebay. The purple cart with the crooked label is a Chinese (?) translation of Pokemon Yellow. It saves sometimes, but it's not reliable. The grey cart is Pokemon Crystal, the normal English version. It appears to be the regular game, I haven't found any changes while playing it. It doesn't save at all, despite having a battery. If y'all have seen these before, or know who made them, let me know.
