Bung
From PHWiki
Legendary Chinese company that made backup units and flash cards for a wide variety of game consoles, both stationary and portable.
Nintendo got an import ban on Bung's GB XChanger cards in the late 90s early 00s, which caused Bung to rebrand their cards to Mr Flash, and since then they have scattered and their presence has become less obvious. For instance, Bung sold GBA flash products under the name Visoly.
