R4 Video Games Memory Card，3DS Game Flashcard Adapter Support for NDS MD GB GBC FC PCE

The blank r4 cards worked best for me as I was able to customize each card specifically for each kid. They have enjoyed playing each of the different games Ive added. You just need to know where to get the software program a d the games to download and reddit is a good source for information. Im planning on buying more for the my other kids and myself.

Arrived looking just as it appeared in the listing. Took under 5 min to set up. I downloaded software kernel from ace3ds (.com) There are two options, a simple one, and one with preinstalled emulators. Both worked fine. I tested .nds .gb .gbc .gba .nes .sfc and .md files and those all seemed fine. I found another site gbatemp where I found some other themes and emus etc
