I am completely new to RPI and I just purchased a PI4 for gaming usage, planning to use for GBA, PS1,2,3,PSP games.
Here is my DF -H, how do I get that extra 26GB from /dev/mmcblk0p9?? As I do not have enough space for my games. The retropie folder is in the /dev/root directory while there is a 26GB in /dev/mmcblk0p9. Pls Help, Thank You.
