User Reviews

John DataSync2 functions as a Dropbox-based hub to back up and sync emulator game saves. Users praise its concept and portability, centralizing saves across games and devices (like a memory stick). However, there are recurring Dropbox linkage issues, permission loops, and 'currently disabled' errors, plus data loss risks when unlinking. Reliability is inconsistent, with freezes during saves and setup headaches. There’s strong demand for Google Drive/Box support. When the cloud link works, the backup flow is praised and can be very useful.

Dropbox-backed hub for backing up and syncing emulator game saves

Cons

Recurring Dropbox integration failures: 'currently disabled' errors and permission loops across devices
Data loss risk when unlinking or re-linking accounts, leading to lost saves

No Google Drive/Box support and requests for alternative cloud storage

it's like having a memory stick 😅

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.
