PAL

In 1990 Nintendo released the Super Nintendo Entertainment System (Super NES, Super Nintendo or simply SNES) to the Japanese market. In the following year distribution began in the United States followed by Europe and Australia in 1992. If you're looking at the pictures and thinking, 'that's not a SNES!', you probably grew up in the US where the console's casing was redesigned to be more anglar. As the PAL versions were modeled after the Japanese Super Famicom design, this also affected the cartridge shape. US versions being more boxy and the Japanese and PAL region versions maintaining the more curved shapes. This also means that in some instances in addition to the regional lockout chip, cartridges can't physically be used in a console they weren't designed for without the use of a physical adaptor. While the US version was reportedly intended to give the console a more, mature or serious appearance, in 1997 it was again re-designed giving it a more rounded look before being discontinued in 1999.
