RDB file type is a database file type. This file format is used by Nintendo64 game console.
The emulators which are created to run Nintendo64 games require ROM files to load the actual game. RDB files provide referencing for such ROM files. These files do not contain actual data of the game but are required for running the game while using emulator. Generally RDB files contain list of games which are created for Nintendo64 emulator applications and emulator references the game name and other details from RDB file when loading the game content from the ROM file of Nintendo64 game.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .RDB file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .RDB file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .RDB file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
There may be several reasons why you cannot open the file with .RDB extension. Directly on this website you can find a solution of the most common problem with the .RDB file – that you do not have on your computer the appropriate program to open the file.
