Krikzz has posted a (few) firmware updates for the Game Boy Advance Everdrive. They add support for the same savegame upgrade the other Everdrives have been receiving, which copies the savegame file back to the MicroSD card each time the menu is loaded: http://krikzz.com/pub/support/everdrive-gba/OS/
Another interesting feature added to this firmware is developer-focused; Now dev’s have the option to program their games to use a specific ROM ID to select save types. According to Krikzz:
If ROM isn’t exists in bram-db then first char of ROM ID can be used as save memory selector:
1 – EEPROM
2 – SRAM
3 – FLASH-64
4 – FLASH-128
Number should be stored as char, eg 1 equal to 0x31 in hex format
There were actually two small fixes issues after the initial v1.13 firmware, both fixing small bugs introduced by the firmware. Simply get the latest file from the link above for the most up-to-date version. The full list of changes are below:
