So instead of checking each file in the main flashing routine, check first the files presence on the SDCARD, and if yes, indicate with a LED above the chip, using a color white, the presence of the file.
If the chip is there, but the rom file is abscent, then the LED above the chip should be GREY.
This is very handy to show the user before the flashing routine actually executes, which chips will be flashed and which not.
