I know it's not NES, but the game we got in Mario All Stars for SNES was called "The Lost Levels", which I know was released in Japan as SMB2. Generally I just call the NES version Super Mario Bros. 2J.
What I wanted to know is was this game a Famicom Disk System game only or was there a Famicom port as well? I had heard somewhere it was ported and you could go to A-1 from the start. In the Disk System game you need to beat it 8 times before you can access level A-1.
If anyone's got any info, I appreciate it.
