[Techtoolslist] Fluke on Mario Bros.

[John Robertson]

It appears this is normal (not saving Free Play setting) - oddly enough. 
Some online searching shows up that others have run into the same thing, 
game won't keep Free Play setting when power is cycled. To be honest I 
haven't tested the High Scores if they reset or not as I am not a good 
enough player. That feature may actually work.

Arcadeshop offers a kit for saving Free Play for Mario Bros. So that is 
another clue that it is not kept in the CMOS RAM for some reason...
