Title: Backport overlay failed with "Operation not permitted" on ShadowMountPlus 1.6test8-fix1

Hi,

I am using the latest version: ShadowMountPlus 1.6test8-fix1 (12.00 fixed), but backport overlay is still not working for me.

My PS5 firmware is 10.01.

My game folder is here:
/mnt/usb0/homebrew/PPSA17525

My backport folder is here:
/mnt/usb0/homebrew/backports/PPSA17525

Inside the backport folder I placed the backport files, including:

- fakelib/
- sce_module/
- eboot.bin
- EOSSDK-PS5-Shipping.prx
- libPlayFabMultiplayer.prx
- Party.prx

So the structure is basically:

/mnt/usb0/homebrew/PPSA17525
/mnt/usb0/homebrew/backports/PPSA17525

I also attached screenshots of my folder structure.

However, ShadowMountPlus fails to apply the backport and shows this in the log:

[00:19:56] [IMG] backport overlay failed: /mnt/usb0/homebrew/backports/PPSA17525 -> /system_ex/app/PPSA17525 (Operation not permitted)
[00:19:56] NOTIFY: Backport overlay failed: PPSA17525
/mnt/usb0/homebrew/backports/PPSA17525
0x00000001

From the log it looks like ShadowMountPlus does detect the backport folder, but it fails when trying to overlay it to /system_ex/app/PPSA17525.

My current config.ini is:

debug=1
mount_read_only=1
scan_depth=1
stability_wait_seconds=15
kstuff_game_auto_toggle=1
kstuff_pause_delay_direct_seconds=15
kstuff_pause_delay_image_seconds=25

Am I using the wrong folder structure for backports, or is this a bug with overlaying to /system_ex/app on my setup?

Thanks.
