Ciao, anche io ho problemi con amiga.
Ho seguito questa guida: https://github.com/recalbox/recalbox-os/wiki/Amiga-on-Recalbox-(EN)
Io ho un po' di rom in formato adf, per le quali sembra sufficiente avere le rom copiate nella cartella corrispondente.
Ho installato i bios, sembrano corretti (allego l'immagine da dove si vedono checksum e spunte verdi:

Quando entro nella sezione vedo l'elenco dei file ma quando faccio partire uno dei giochi dopo qualche secondo di schermo nero, si ritorna alla lista.

Ho fatto una prova anche con qualche file in formato whd.
Scompattati i file in una cartella, eliminati i file .info, creato un file vuoto (txt) e rinominato con il nome del gioco .uae

Anche questo sistema non mi funziona.

Dove sbaglio?
Grazie!

@boxcarpilot now it is working. I've done a fresh installation after downloading the full image.
I guess the problem is noobs.
Thanks.

I've found my version: 18.2.09... is it possible?!

Hi @boxcarpilot,
I'm new to recalbox and raspberry world, but immediatly seems to have problems.
I just installed recalbox using NOOBS and after a couple of tries I've came up with your same problem.
My saved files are overwritten at reboot. This happens to roms, configurations (language, date/time, controllers).
And this happens if the changes are made through the ui of recalbox, via ssh or via webpage on the local lan.

By the way, I've a couple of other things:

1. the partition at the end of the installation has not been enlarged, so it is too small to host roms - is there a way to take all the space available?
2. haven't managed to use these instructions https://github.com/recalbox/recalbox-os/wiki/Load-your-roms-from-a-network-shared-folder-(EN) to load from a NAS my roms, I guess because at reboot everything is gone. I'll double check this.

Then i found your post. I will stop trying to understand and will wait for updates.

A last question. How do I know my exacly installed version of recalbox? Nothing emerges from the web page...
