Upload a ROM from Your Phone

Select the upload area and choose the game from Files, Downloads, or your device's file picker. On a computer, you can also drag files onto the upload area.
For a supported game with multiple files, choose the files together.
Select Upload ROM.
Keep Rebit open until the upload completes.
Open the game from Library.

Only upload files you are allowed to use.

Large Upload Progress and Cancel

Watch the upload progress and keep your device awake. Use a stable connection for large games. If you chose the wrong files or the upload stops, cancel it and start again after checking your storage.

ZIP Extraction

ZIP behavior depends on the game:

Cartridge games: Rebit looks for a supported ROM inside the archive. Keep one game per ZIP.
MS-DOS: choose MS-DOS to keep the ZIP intact as the game's DOSBox Pure package. Do not extract just one executable from a game that needs the rest of its files.
Disk-based games: include the complete supported media set, including files referenced by a CUE file or playlist. You can also select the extracted files together.

Upload a ZIP by itself; do not mix it with loose disk files in the same upload. If an ordinary ROM archive fails, extract the ROM and try uploading it directly.

Multiple Disks and Playlists

Keep a multi-disk game's files together as one upload. A .cue or .m3u file refers to other files; include those files with names matching the references.

For supported computer disk sets, use Disk Drive in the in-game menu when the game asks for another disk. See Amiga for Amiga disks, Kickstart BIOS, and saves.

Import Games from RomM

Connect your own RomM server in Settings.
Open Upload and select Import games from RomM.
Search for a game and select the items to import.
Select Import and wait for the queued imports to complete.
Check Library for the imported games.

If an Upload Fails

Check the file type and choose the correct system.
Check Storage and Pro for available space.
Check that disk sets include every referenced file.
For DOS ZIP files, select MS-DOS explicitly.
Retry a large upload on a stable connection and keep the app open.
