I booted up my DS today to play some Sonic when suddenly. *LOADING...* A couple of minutes later I returned to my DS and it was STILL loading. So I thought, "This is when my R4 Backup comes in use!" So I inserted the Micro SD reader into my PC and it asks me to format it. So I tried. "Windows could not format." "Please make sure the disk is inserted right." Being me, I blowed at the reader and tried again. Same results. Then I went downstairs and tried it on my dads PC. It crashed. I can't afford a new MicroSD card so what can I do? - He lives in my R4..
