from the original purchaser of the unit. This system has boggled
my mind for quite some time and now i can give it a rest.

all my adapters are official nintendo products,not performance

concerning the “ac adapter” i guess i could’ve been more
specific.out of all my vb units with official nintendo
ac adapters (not the taps) that say made in japan,this one
came with a official nintendo ac adapter that says made in
china that has a different texture of plastic than the ones
made in japan.pluss the part that plugs into the tap is a
darker grey than the ones made in japan . both different
adapters mention snes and virtual boy on the plastic.
i also forgot to mention that the sticker on that unit is
alot shinier than the rest.
WOW check out the post before this one.
its another vn9 unit

Heres what the seller of the unit sent to me when questioned
about the serial

Well here it is, next to a normal serial #.here are the differences i could find between them.
1) the barcode,letters and the numbers are bigger in size
2) the sticker itself is a bit more rounded on the corners
3) its hard to see in the pics but there is old sticker residue
In the corners not fully covered by the rounded sticker,
indicating there was once a different serial# at one point.
4) out of all my other vb units with ac adapters made in jpn
this one came with an ac adapter made in china with different
textured plastic.
