@hitmaker Your SD card is probably corrupted.
You can try to recover it with Windows, but, it may be necessary to reinstall the system and, perhaps this will not even solve ...
The recommended is to use a small SD card for the system, and put the ROMS, BIOS and other things in external storage.

@lcm_br what don‘t you know? Look for msx and decide.

@voljega I found the Roms, they were saved onto the windows hdd instead of the flash drive. The issue I'm having now is no boot. Saying something about not able to write no space. So since things were saved to the hdd I'm trying to reset with grub but I don't think its possible.

@Leech i don't trust windows to read ext4 partitions. And your story proved it ...

Still i'm glad you recovered everything this way, congratz 🙂
