Pico-8

hi! i bought a MIYOO MINI V4  to play pico 8 games

i've followed these instructions:
Drag the app folder from the releases page into /mnt/SDCARD/App/ (so it becomes /mnt/SDCARD/App/pico). Warning: If you use FTP and Filezilla, you must set your transfer type to binary or it will corrupt binaries on transfer.

Drag your RASPBERRY PI pico8_dyn and pico8.dat into /mnt/SDCARD/App/pico/bin (If the directory doesn't exist, you can create it). You can purchase Pico-8 here.

and i cannot manage to see pico 8 in the apps menu as the tutorials say.
also instead of all the apps they show i only see 4. instead of multiple apps as in the tutorial i followed
