Ok so i'm a total newb i hope this question hasn't been asked 1,000 times, but with the x-ecutor2 chip do i need,or is there any benefit in flashing the bios? i've put evox on and it plays every type of disk i throw at it, connected it to pc & it copies so easy i can't belive it, but evox just shows bios unknown on my screen, so is there any point in flashing it if all is working well? a mate said it opens up new features on evox but i have my doubts, any advice peeps?
