The Design and Implementation of laffer1

I purchased a copy of Super Mario All Stars on Ebay for the SNES.  I used to love the lost levels (Mario 2 in Japan).  So I spend $20 for this cartridge including shipping.  The game doesn't work.  The screen is black.  I've tried cleaning it with no effect.  I never leave bad feedback on ebay, but in this case I decided it was worth it.  $20 for a bad game is very irritating.  I could have purchased it from someone else.  Aside from finishing my essay, I planned to play that tonight.  I'm very pissed.
