 +===== Flashcart errata =====
 +
 +==== Last sector access crash ====
 +
 +Some flashcarts crash upon trying to access the final sector of the microSD card. This generally appears to affect R4/Ace3DS and their clones.
 +
 +Workaround: Partition your card in such a way as to leave a few kilobytes/megabytes of space unused at the end.
 +
 +Reproduced on:
 +
 +  * R4 Revolution
 +  * Gateway Blue
