• RomCenter Platform Databases Location: When Default is checked, RCDBM uses the Settings / RomCenter databases path to find this platform's databases. When Default is unchecked, the user can select a different path, in which all databases for the selected Platform must exist (in the same folder, not in any subfolders).
• Base ROMs path: The path in which the actual ROMs of the selected Platform are located. The organization of the subfolders in this path must match exactly the folder structure of the respective Platform, as shown in the tree at the main screen.

Last-level nodes in the tree also contain the TOSEC version of the dat (i.e. “Amstrad CPC\Applications\[BIN] (TOSEC-v2014-10-28_CM).dat”. This part must not exist in the respective folder name in the ROMs path. RCDBM will try to match the treenode “Amstrad CPC\Applications\[BIN] (TOSEC-v2014-10-28_CM).dat” to the actual folder “Amstrad CPC\Applications\[BIN]” under Base ROMs path later-on, when the “Start Process” button is clicked and the actual work begins.
