i've been looking for these two ROM packs for NES forever First mystery ROM: It was called 101-in-1 or one of those bootleg multiple games in one cartridge and there is a menu list of all the games you can play and at the bottom there is two crab like characters walking towards the center from the left and right and when they meet they pull away from each other but different color. The games in this cartridge were insanely tough. Second mystery ROM: side scroller but there is this weird dune like worm monsters, definitely not kid friendly as the game had creepy images but it was the hardest game I ever played on the NES
