The games i played:

Duck hunt: i remember that i suck playing it because of the bootleg gun not working properly

Super Mario bros (pirated): the title screen was changed to a image of mario giving a peice sign drawn poorly next to a castle next to a 2 and marios name is replaced with score

It turned out to be a hack of the pal version because the music is fast and high pitched

I also suck at it because i constantly keep dying from that first goomba

I later improved playing it again on my pc

Hope i could get a nintendo switch years later

Before anyone asks im gonna get the original version
