This configuration file is for changing default game settings. 
First number for save type, second number for game config. Game config options can be mixed using addition (1+2=3 for rtc+region).
ROM ID or CRC HI can be used for game detection. (check "ROM Info" menu for details). Identificators should be entered without space.
Upper records has priority over records below.
Begins from OS 3.07 supported full ID length (2-6 symbols)
Also there is specific ID reserved for developers 'ED' With this ID cart will load config from ROM header (one byte at offset 0x3F)
Few samples below.
------------------save type
0 - OFF
1 - EEPROM 4k
2 - EEPROM 16K
3 - SRAM
4 - SRAM 768K
5 - FLASHRAM
6 - SRAM 128K
------------------game config
0 - OFF
1 - Force RTC
2 - Regio free ROM. Use native system region for game launch. For applications without region lock
