It was just a multidisk of some SNES games on an emulator for PlayStation 2, titled "Super Mario 4". I bought it circa 2007-8 and then I had NO (I SAY NO) knowledge of Mario series. But who thought that it makes me later (since about 2013) a die-hard Mario (but specially Wario) fan and also pirate? (oh, another characteristic of Wario.)
The games that it had:
SUPER MARIO KART U (U in all of the following ones stand for universal, I think. Seen this in brackets when you download a ROM dump?)
MARIO (it was Super Mario World)
MARIO S EARLY YEARS - PRES U
MARIO S EARLY YEARS - FUN U (... with numbers, eh.)
MARIO IS MISSING U
MARIO S TIME MACHINE U (why so unlucky to have 4 edutainment games in a row?
)
SUPER MARIO ALL STARS WO
SUPER MARIO ALL STARS U (you may know the difference.)
SUPER MARIO RPG U (sadly, it was freezing after the title screen.
)
SUPER MARIO WORLD U (Why it's so repeated?
)
TETRIS DR. MARIO U
YOSHI S ISLAND U
YOSHI S SAFARI U
YOSHI S COOKIE U
P.S.: Ow, I found its cover art also. here it is:
