Note: The Leapster2 was last sold in 2012 and is no longer supported. The LeapFrog Connect software for this product is offered as-is.
**This question and answer is not applicable to Leapster2's that come with a built in SD card. Leapster2's with built in SD cards do not have an accessible SD card slot in the battery compartment**
LeapFrog recommends an SD card of 2GB or smaller(physical dimensions of a standard SD card are approximately 1 inch wide and 1 1/4" high)
The Leapster2 does not support the new SDHC (Secure Digital High Capacity) cards or mini or micro SD cards inserted into the L2 device with an adapter.
The Leapster2 will overwrite any existing files written on your card from another device. Be sure to use a new card or a card with data that can be erased.
