Sorry no, but there is a way that most of the times work.
First load MyBIOS, so you have the reset-menu behind SHIFT+CONTROL+TAB.
Then go back to the cartridge (SHIFT) and do your FAT32-thing.
When the game loaded is polite and leaves the MyBIOS running you can use SHIFT+CONTROL+TAB
or when not perhaps hold-SELECT-down and do RESET.
Merry xmas
