I have yet to see an old existing game get a patch to use the extra New 3DS power

SmileBASIC is one that has been made to take advantage of the new 3DS power, which is why there is a difference in performance.

old 3DS games like pokemon perform identically on both types of system. loading times might depend on your SD card speed (if it's digital or something).

but old games like pokemon don't suddenly have better 3D, they run like they did on the old 3DS.

chances are you don't own two 3DS systems, both with SmileBASIC. if you're wondering what MP TEST did, this is it.

oh and these numbers might be meaningless. I don't know what you'd do to SmileBASIC to cause it to lag on Old 3DS. but also don't take this as "every game runs faster on New 3DS!" because that's not the case, games have to choose to use that power. SmileBASIC just happens to ;)

i feel spoiled having three 3DS systems
