I appear to have solved the issue - I changed the emulator to lr-pscx-rearmed and it works fine!

Thanks for reading

Or, if you need Windows compatibility without third-party drivers, use NTFS or ExFAT. Both are better than FAT32 and can be used out of the box in Windows and RetroPie.

Which features do you need the FS to have exactly?

Can you try adding over_voltage=1 to config.txt?

Why don't you transfer your ROMs over the network to the new SD card ? You should be able to access your ROMs on the USB from your PC, just copy them to \\retropie\roms\<system> and that's all. See the docs page on transferring ROMs.

For the missing icons - re-install the retropiemenu package, it probably stored its artwork on the USB drive.

Sorry for being vague.

The games go through the usual runcommand launch menu, then black screen, then back to games list.

The runcommand log for a nes game look like this:

Parameters: Executing: /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-fceumm/fceumm_libretro.so --config /opt/retropie/configs/nes/retroarch.cfg "/home/pi/RetroPie/roms/nes/Metroid (USA).zip" --appendconfig /dev/shm/retroarch.cfg

And for a PSX game look like this:

Parameters: Executing: /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-pcsx-rearmed/pcsx_rearmed_libretro.so --config /opt/retropie/configs/psx/retroarch.cfg "/home/pi/RetroPie/roms/psx/Alundra.PBP" --appendconfig /dev/shm/retroarch.cfg Memcard 2: disabled Starting PCSX-ReARMed Running PCSX Version 1.9 (May 28 2019). psxMap: warning: wanted to map @80000000, got 0x6f50a000 Init new dynarec testing if we can run recompiled code.. test passed. warning: RAM is not directly mapped, performance will suffer Mapped (RAM/scrp/ROM/LUTs/TC): 77000000/1f800000/1fc00000/08000000/7018f000 found BIOS file: SCPH101.bin RGB565 supported, using it plugin: plugins/builtin_gpu plugin: plugins/builtin_spu plugin: plugins/builtin_pad plugin: plugins/builtin_pad Plugins loaded.

Both these games work on a fresh mount, but not on my current library.

Thanks.

Thanks! that was exactly the problem!

@chuckyp said in Games on USB-Drive are not refreshed:

@clyde not trying to make things more difficult. Just giving another option in-case he can’t get the official method to work.

And I mistook you for the TO, that's where my last paragraph about helpful details came from. :*)

@BuZz I already have my two systems set up and working after the manual copying. I'm actually out of extra Pis and USB drives at the moment. If it's broken it's not bad enough that I wasn't able to fix it so it didn't really bother me.
