A colleague of mine from college works for the gaming commission in our state (not NV.) had a 'catch-up' dinner a little over a decade ago. She intimated that one of her duties was to take the ROMs from slot machines and run them through a device that calculated the hash [0], to make sure that the code matched an 'approved' code base.
[0] - I can't recall whether it was MD5 or SHA-1, but definitely one of the two. Hopefully that's changed by now!

The audit requirements were impressive, although most machines now are quite a bit more advanced (at least outside of Nevada), and basically run a gaming computer with a hardware root of trust and an RNG dongle.
