Notes
Example code to import "game.8xp" in the root directory to RAM:
ld hl,sFilename xor a ;do not overwrite existing variable and create in RAM U_CALL MSD_ImportVariable ... sFilename: DB "/game.8xp",0
If you are writing an application, you must copy the strings you use to RAM first, or else usb8x will not be able to see them.
