Don't try to go into an empty directory with this device. I've managed to get the thing hardlocked with a beeping sound when I accidentally went into an empty directory on the sd card and scrolled down. I'm now trying to get the battery compartment open but am failing with any screwdrivers I have.
Try to update the latest firmware to solve your problem. Here is the link: www.k1gbasp.com/download/revo-k101-fw-fix-sav.zipThis is a K101 software problem and idk if it's the same as k1 GBA SP, but I'll post here anyway.
On the japanese version of Pokemon Emerald, when i view a pokemon's moves, the screen gets very glitchy.
Randomly colored pixels are scattered across various areas of the screen and it is difficult to discern the text.
