Save Type is the type of memory that a ROM uses for saving your games. If an incorrect type is chosen, the ROM may not save game data and only save states will work correctly. This option is by default set to All Used Types, this allows the ROM to save all feasible types, but it will use more disk space. However, this is typically best for maximum compatibility if the save type isn't known in the INI. The other save types are:
- SRAM, EEPROM, FLASHRAM.
These are various types of Non Volatile (stays resident without power) RAM that are used to store game save data. What type the cart uses is based on what the manufacturer placed in the cart during production. Setting this to any of the wrong settings may prevent you from using internal game saves. - MEMPAK: This uses the a MEMPAK file, or this is overrided by the MEMPAK attached to the controller, depending on the settings of certain input plug-ins.
- First Used: This sets the ROM to use only the first detected save type. It will not use any others.
