No, its none of the above...
Some newer nintendo games like ben 10 alien force and metal slug 7 have a protection code on them built into the arm 7 part of the coding.. These games are to stop trying cards like r4 and m3 from playing.. and it works.
Do a google search for arm 7 fix and you will find a few programs that can sort it out, but it can be a real pain in the butt trying to find the arm 7 from another game that will work.. a bit hit and miss but if you try enough you will get most newer games to work
