I
have tested the games on an original Japanese Super Famicom. The games loaded fine and I could play the games without any issues.
I do not test to see how well the battery works if the game
includes a battery.
Please remember that this is an old
vintage game so it may require extra cleaning and repositioning so the
cart can get a good enough connection for it to work.
It
comes with the original boxes. Super Mario collection has its manual but it is dirty and damaged. Mario Kart is missing its manual plus it is inside a plastic shell instead of coming with the plastic blister. The
games have wear, marks, scratches and discoloration. The Mario Kart has a sticker with someone's name on top. The
boxes have wear, creases, bends and scratches. Please see the
included pictures for
an idea of the condition of the game.
