Kernel panic not syncing on Batocera (Pi 500 and Pi 5 16gb)

Hello, just swapped my old batocera microsd to new Pi 500 i have, and it wont boot, ending on Kernel panic - not syncing, the same happens on Pi 5 with 16gb ram. The sd card works on Pi 8gb.
What can I do to get it working (eeprom on all Pi's is on latest version)?
