E-reader only works on DS Lite because it doesn't fit on a regular DS x__x works on gameboy player if you have that though

I've got an E-reader and Tons of E-reader cards. I have most of the TCG cards that have E-reader features (lol I have collected the TCG cards since the first set) and I have 2 of the Battle E-card sets (stopped selling them before I could buy the last one

I think Hidden Ruins). I Also have all the E-reader nintendo classic games and of course the infamous Eon Ticket card

My sister also has like 2 packs of the animal crossing e-reader cards, she wanted more but they stopped selling them. I even had an extra eon ticket card but I gave it away to a friend in exchange for a legit mew from the toys r us promotion...
