Stern still using a hardware lockout like with the LOTR LE that could theoretically be bypassed with a chip? Just seems odd to me that it doesn't really look like anyone's investigated this. I'm not a coder or engineer so I'm just throwing my interest in the subject out to the wind, and frankly the difference in most of the games isn't enough to justify going to the trouble to bypass the lockout, but I see it as an interesting technical issue.
If you can't build in all the LE mechs, the odds are you game isn't going to work properly anyways, so it's not like you could install LE code on Metallica just to enable proper spinner functionality...you'd still be missing all the other playfield differences and the code would just be like "Well none of this crap works!" You'd never be able to get a coffin lock, lol.
