The rebase

The rebase

The rebase copies the checked games to the destination, following the chosen target architecture. Rebase to…, in the main window, opens the window below.

The table at the bottom tells what will be written for each game, before anything is copied.

---

Destination and architecture

• Destination: the SD card, the USB drive or the folder that will receive the games
• Preconfigured target architecture: sets the folder names and the rules of each system. See Target architectures

---

Files

Setting	Role
Archives	Extract as the architecture requires (recommended): only the systems whose emulator cannot read archives are extracted. Never extract: everything is copied as is. Extract everything (except romsets): every archive is extracted
Extracted files	Automatic: a single extracted file takes the name of the game, several files go to a folder named after the game. One folder per game: always a folder
Convert files with external tools	Enables the conversions of the Conversion column. See External tools

---

Metadata

Setting	Role
Copy covers	Copies the cover of each game to the folder set by the architecture
Generate…	Writes the metadata file of the target. The label carries its name: gamelist.xml, miyoogamelist.xml…
Back up the existing file	Keeps a dated copy of the existing file, for example gamelist.xml.20260920
Metadata language	French or English. A description missing in French is taken in English

An existing metadata file is merged: the games already listed and the favorites are kept.

---

Copy

Setting	Role
If file exists	Ignore: the file already there is left alone. Overwrite: it is replaced
Concurrent copies	Number of games copied at the same time. On an SD card, 2 to 4 is enough
Retry attempts	Number of new tries after a failure
Retry delay	Wait, in seconds, between two tries

---

The games table

Column	Content
Romset	The archive is copied under its original name, with no extraction and no M3U. Required for arcade
M3U	A playlist gathers the discs of the game
Extraction	The archive is extracted instead of being copied
Conversion	The external tool that will convert the game, or None
Output	What will be written. On hover: the list of files
Status	Ready, then Copying, Extracting or Converting, and finally Done, Skipped or Failed
Error	The reason of a failure, or a warning about a cover, followed by its error code

The button at the end of the row removes the game from this rebase and unchecks it in the library.

Values of the Output column

Value	Meaning
Copy	The file is copied under the name of the game
2 discs + M3U	The discs are numbered and gathered in a playlist
2 versions	Several versions of the same game (PAL, NTSC, revision), named after their RomStation label, with no playlist
Game folder	DOS or Windows game: its whole folder is copied
Converted to .chd	The game goes through an external tool
No mapping	The architecture has no folder for this system: the game will be skipped

Setting one game apart

Romset, M3U, Extraction and Conversion are pre-filled by the architecture and can be changed row by row for the current rebase, without modifying the architecture.

A rule that does not apply to the game is off and greyed out, and its tooltip tells why.

---

During the rebase

• Start launches the copy, after checking the destination, the available room and the systems with no mapping
• Pause suspends copies between two files
• Cancel stops everything. A running extraction or conversion is cleaned up, a plain copy may leave an incomplete file: see Limitations
• Show log opens the rebase log

---

At the end

A message sums up the result and the table keeps the status of each game. Open folder shows the destination in Explorer.

    .Chrono Cross\
        Chrono Cross (Disc 1).cue
        Chrono Cross (Disc 1).bin
        Chrono Cross (Disc 2).cue
        Chrono Cross (Disc 2).bin

• A cartridge stays in its zip
• A Playstation game is extracted. With the Hidden folder option of the architecture, its files go to a folder whose name starts with a dot and EmulationStation lists only the M3U
• The internal names of a multi-file archive are kept
• A character that Windows forbids in file names is replaced: Castlevania: Aria of Sorrow becomes Castlevania- Aria of Sorrow
• RSRebase never deletes anything on the destination. See Limitations
