Yeah. There are also enough mmkv files in 3.5 to play with, just not eac_config.
Code:
BOOX:/data/data # find . -name '*mmkv' | xargs ls -l
-rwx------ 1 system system 8192 2024-10-28 05:59 cloud_note
-rwx------ 1 system system 4096 2024-10-28 05:59 cloud_note.crc
...
Lol. I don't know how your mmkv eac_config is but the mmkv's I have are pretty stupid. The idea of mmkv is supposed to be lean and mean key/value. If all your values are JSON structures formatted with whitespace there's not a lot of savings.
