Puzznic I dumped a few years ago from a freak chance where I got a board where the MCU protection bit wasn't set. This will help confirm if it's good or bad or faked or what.
Tokio was dumped a few months ago, not sure if it was added to mame yet, re-included here for completeness of the MCU stuff done by Shoutime with the 68705 dumper.
I'm guessing on Fairyland Story, it looks like an MCU dump came from the year 2000 so it's either a freak chance the MCU didn't have its protection bit set and this is confirming it's correct or not, or the MCU dump was taken from a bootleg version and this is confirming whether it's an actual dump the bootleggers extracted or whether they just faked it. I haven't heard any specific talk about it.
