They should be stripped
THERE IS NOT 8MBIT OF DATA INSIDE OF THEM
There's not even a valid argument for this any other way, any time you see data duplicated in the dumps it's coming from the exact same physical bits inside a rom due to address lines going nowhere.
I respect your work, but you really are making yourself look like a fool with this one.
MAME currently completely misrepresents the storage capacity of each cart for any dump that isn't stripped, a grand total of 0 of them can actually store 8MBIT, that physical capacity does not exist inside of them.
You wouldn't stick a 1MBIT rom in a reader, read it as 8MBIT and claim the duplicate data is correct, that's what is being done here, just because there's a bunch of epoxy etc. around those roms doesn't change their capacity.
