Super Mario Bros. The Lost Levels Deluxe:
Here'* one, but it has a disclaimer:
I guess you came here for the Rom, so here it is: download. Since the game was only designed for the Japanese Nes (aka Famicom), you also need to extract the file disksys.rom in your rom folder: it works as an adapter. It'* all included in the zip, just don't forget to unzip both files. On startup, you will get a few seconds of black screen. It'* normal.
WARNING: Playing this makes my computer quite unstable (something to do with the Nes/Famicom rom adapter, no doubt)... There'* absolutely nothing a good reboot won't fix, but you've been warned... Save everything that must be saved before you try to play, in case it makes you crash
Here'* another one. It also comes with Doki Doki:
And this one says to put the disksys.rom in the emulator folder?? Don't know which is right, but it shouldn't be too hard to try both
