i ordered it of ebay and it was in us packaging but not correct one. the game cartridge has the wrong picture and the same with the booklet. it looks stretched and it wont fit in properly. any help wantedWhy wont mario and luigi partners in time work on the dsi?
ask the guy you got it from if it is playable on dsi. I was looking all the time on ebay for this game and we asked and they always say you cant play it on the dsi.

For the picture there are two different pictures, one with mario and luigi close to each other and one where there is a mega mario. it does not affect the game.

All the game's I saw that had US post said you cant play it on dsiWhy wont mario and luigi partners in time work on the dsi?
it's a dud. Send it back.Why wont mario and luigi partners in time work on the dsi?
Is it mario and luigi superstar saga for the GBA?

that would explain that

if it doesn't fit in the cartridge its either that or a dud

but just be careful, if u import games from overseas, the dsi is region locked anyway

and it wont let u play those games
