Fails to access local storage and stuck in an infinite loop of requesting access to the same crashing file app. Possible issue only on Samsung phones.

Seria bom usar o Google drive para sincronizar, o dropbox tem limite de dispositivos para conexão na opção gratuita.

Para quem ta perguntando onde estão os apps John NES e SNES, não se preocupem, pq agora criaram o app que emula nes e snes se chama John NESS, assim como os de gameboy que é o John GBAC que emula gameboy classic, color e advance num app único. Reclamação: Os anúncios após fazer qualquer ajuste nas configs são realmente desnecessários.

Absolutely love that this is a hub for the games and save files to upload to using Dropbox. Really added to the impression I had when I found this.

Unfortunately it's not working. I don't know if it's an issue with Dropbox itself or the app, but when linking it it just reloads the "allow" page and the app just closes itself, so i can't enable sync anymore.
