It was definitely 100% unplayable, there were no targets to shoot at and the game would hang as soon as you attempted to start it or if you let it play the demo. The dallas does all the calculations and maths for the targets appearing and movement of the targets.

I guess somebody felt UNEMULATED PROTECTION was a 'more accurate' way of saying MACHINE NOT WORKING or something since both give red screens.

The fact it wasn't marked as NOT WORKING in previous releases is definitely the mistake here, it's very much something that has been promoted to working in 0.191.

The unemulated protection flag seems ambiguous anyway, if the protection simulation on a game isn't trusted well enough to be sure the gameplay is correct, then the driver should be marked as NOT WORKING anyway. If it is instead intended to be used for all cases where protection is simulated, not emulated, even if that simulation is 100% (eg silly cases like Semicom 0x200 byte code transfer) then it shouldn't be a red screen (and needs adding to a LOT more drivers)

I've even seen cases where it seems to have been used to tag things like hardware collision detections being wrong, which isn't protection at all IMHO while in the case we've seen here it was simply (inappropriately) used as a substitute for a proper NOT WORKING flag.

Given all that, I'd say the most important thing to apply in cases like this however is common sense.
