every single thing of this nature would have to be dealt with on a case-by-case basis.

there's no 'easy' solution at all.

when it's bootlegs like this, or random gambling games that were never documented who even knows what is out there.

many you'll destroy just trying to work out what they are / how they work too.

then you've still got the problem of people killing off boards / chips on purposes / not looking after them properly because they know they can just put a de-suicide set on them, even if it's basically then running bootleg code instead of the original. (this is a problem for the FD1149 protected System 32 games, it's a battery backed MCU for which there is no dumping solution, but because it appears on the surface to just have a simple task everybody is just letting them die and running bootleg code - the last time I was told somebody was 'working' on this, it turned out 'working on it' meant just creating their own set of bootleg programs)

there are rare Japanese games using battery backup protection too eg. "The Bounty (set 2)" clearly uses some kind of RAM + suicide battery for the first 0x100 bytes of code, as what's there simply exists to draw the error screen when you boot it in MAME right now. Who knows if the code in the parent set is the original code or is really a desuicide / bootleg from back in the day with something bootleggers recreated. Again, no solution, no chance of something that rare being lent out, risk is too high.
