marko maybe you lose it because of the softreset:
if u don't use it and your G6 battery is dead to mantain your save you have to turn off your ds and then on before flash erases! (2 or 3 secs.)
I used: no soft reset, no trim, DoFAT force R/W and game works fine.
The save from last night loaded fine this morningÂ
No need for arm7 fix
Config: Kernel 4.8/u-disk 4.8D with iND release
update both pc and g6 >< not just one of themhm, and did you do anything special when you wrote it out? Save, trim, configs ?
