First appearance

The development unit first appeard on 12/17/2018 when a user by the name of Trash_Bandatcoot started a conversation with a user by the name of ProtonX on NintendoAge. Trash_Bandatcoot asked about any DSi development units. ProtonX used to own 2 “Panda” DSi’s, but has sold them off. Immeadily after that comment, ProtonX has shared the first images, showcasing a Nintendo DSi Development Unit.
