That Mean that gonna explode in 20min if you don't buy a super rare limited Charger!... that's only you can get if you visit the super rare Nintendo Event in Japan!.....
NB:Just Kidding.... is mean is perfect and you should start playing....
Uhmm Is a Download Play Support.... that you can send the game demo to other people.... (Like in Mario Party Ds or Mario Kart you can send the Game Demo to another friends via the wireless connection to play with them....)
I think the CyCloDS work with all the download play support game...
First i Have a SuperDsOne V.2 (This card is my back up game card)
Second i have a two R4 (This card is my Main Card for Gaming)
Maybe soon i buy A CycloDs i not sure....
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
