So I'm my very slow escapade of trying to add games to my NES Classic, I've found some games just will not work. So far, (as best as my memory serves me) the ones I cannot get to work are:
Not booting
Batman Return of the Joker
Bible Adventures
Bible Buffet
Deadly Towers
Final Fantasy 7
Glitchy:
Battletoads (runs glitchy and acts like it's in slow mo mode.)
Mega Man 4 is a little glitchy on the stage select screen but plays fine
Mega Man 5 same as 4
Fixed:
Final Fantasy 3 (finally found an English rom that worked)
Anyone else having problems like this that they have overcome?
Edited to show my current problem games.
I do realize these are all mainly mapping problems. I just figured if they originally worked in the first place, they should still work now.
