mega memory card from interact, see-throug yellow

[Milk Watermelon]

I forgot to put in the title, for Game Boy Color and Pocket.

Does this thing use flash or run on internal battery?

Also, do Dreamcast cards run on internal battery (I mean only to store saves, not to play the games.)

i *think* the mega memory card is flash, not sure though. the dreamcast memory card/vmu is defiinitely flash though. battery in the DC cards is just for minigames and the date/time
