The box has some damage. It started up without any problems on a SwanCrystal. (There is the issue specific to the WonderSwan where it won't start if you insert the cartridge all the way in.) It comes with the instruction manual and postcard, so it's likely a complete set. There is a line written on the inside of the top lid. I also found a WonderSwan Color that has been IPS-modded, so I've added photos. Shipping will be via Takkyubin Compact. Please take a quick look at my profile. "Moero!!
