Storage Management

The Storage Management page shows every ROM file the app has on the device, how much space it takes, and lets you delete files to free up space.

TODO: Storage management screen

What you see​

A list (or grouped-by-system list) of ROM files with:

  • Game title (or filename if no metadata)
  • System (NES, DOS, ARCADE, …)
  • File size
  • Date added
  • A row action to Delete

A summary at the top shows total ROM size and free space remaining on the device.

Deleting ROMs​

Tap the Delete action next to a ROM:

  1. Confirmation dialog appears.
  2. Tap Delete.
  3. The file is removed from device storage.

After deletion the game entry is still in your library — only the actual ROM file is gone. You can re-download it from the Game Detail page when you want it back. Your save slots for that game are preserved.

To delete the library entry too (for custom-imported ROMs), use the Game Detail page → ⋮ menu → Delete ROM (which also deletes the file).

Bulk delete​

For freeing big chunks of space:

  1. Tap Select in the top bar.
  2. Tick the games you want to remove.
  3. Tap Delete selected at the bottom.
  4. Confirm.

ROM file size limits​

There's no hard size cap, but very large ROMs (over ~500 MB) can fail to load on lower-RAM devices due to memory pressure. The app shows an error if a load fails. Performance:

  • NES, GB, GBC — ROMs are tiny (KB to a few MB)
  • SNES, GBA, Genesis — typically under 32 MB
  • N64 — up to ~64 MB
  • NDS — up to ~512 MB
  • Saturn, PSP, PSX, 3DS — hundreds of MB to over 1 GB

See Performance troubleshooting if you hit load failures.

What gets included in this list​

  • ROM files in the app's private game folders (one folder per system)
  • BIOS files (separate row when applicable)

What does not appear:

  • Save state files (managed separately)
  • Settings, caches, etc.

To inspect overall app storage including settings and caches, use Android's system Settings → Apps → DOSGamePlayer → Storage.
