why do i have to keep factory resetting my trimui smart pro s with knulli installed to play games

Hi, I have KNULLI installed on my Integral SD card, and I’m having a strange issue that happens every time I cold boot the device.

If I factory reset the device, everything works perfectly. The games launch normally, the front-end works, and my custom front-end music plays correctly. I’m using custom music in .ogg format.

However, after I completely shut the device down and then cold boot it again, KNULLI loads normally and the menus appear to work, but the front-end music stops playing. More importantly, when I select a game, the game will no longer launch. The games are still visible, but clicking on them does nothing or they fail to start.

The only way I can get everything working again is to perform another factory reset. Once I do that, everything works perfectly again until I perform another cold boot, at which point the exact same problem comes back.

I have not intentionally changed any system settings between the factory reset and the cold boot. This makes me think something is happening during the boot process that is affecting either the front-end, the audio configuration, the emulator configuration, the filesystem, or the permissions/mounting of the SD card.

One other important detail is that my SHARE partition is formatted as exFAT. I specifically use exFAT because I want to be able to remove the SD card, put it directly into an SD card reader, and access the SHARE partition from a Windows PC without needing any additional software.

Could you please help me work out what is causing this? Ideally, I want to keep the SHARE partition as exFAT so I can continue managing my ROMs, saves, BIOS files and other files directly from Windows.

The main symptoms are:

  1. Factory reset KNULLI.
  2. Everything works perfectly.
  3. Games launch normally.
  4. Custom .ogg front-end music plays normally.
  5. Shut the device down completely.
  6. Cold boot the device.
  7. KNULLI loads normally.
  8. Front-end music has stopped playing.
  9. Games are still listed but will no longer launch.
  10. Factory reset again and everything immediately works.
  11. Cold boot again and the problem returns.

So I’m trying to find out why the system is breaking specifically after a cold boot, rather than immediately after the factory reset.

My setup is a TrimUI Smart Pro S with KNULLI installed, using an Integral SD card, with the SHARE partition formatted as exFAT for direct Windows access.
