 ## Getting started
 Using your PC, insert the SD card and ensure it is formatted for compatibility (We recommend FAT32 in most instances).
 
+### Save files
+By default, all save files (whether `FlashRam`, `SRAM` or `EEPROM`) use the `.sav` extension and match the filenane to the ROM.
+Each save file can be found in the `/saves` folder located in the same directory as the ROM and shares the same file name, apart from the extension.
+If transfering a file from a different flashcart such as the ED64, it will be necessary to change the extension of the file to `sav`.
+i.e. for `Glover (USA).eep` you would need to change the extension to `Glover (USA).sav`
+**NOTE:** certain emulator saves may be incompatible.

 ### ROM Boxart
 To use boxart, you need to place png files of size 158x112 in the folder `/menu/boxart` on the SD card.
