(HANs does not work with Super Street Fighter IV unfortunately).
Wait, WHAT!? Could you provide more information about that? I am fairly interested but can't find any decent results.
If you have updated your 3DS to 10.2 or 10.3, you're out of luck. Nintendo has pretty much blocked the easier hax and the only way to do it from there is to have physical versions of either OoT3D, or Cube Ninja, the later has skyrocketed in price from $5 to nearly $90.
If you have not updated,
here is the original thread of the homebrew. The homebrew was updated to 2.5 and with it came HANs. Hackers found that N3DS's clock speed is actually at 804MHz, over the O3DS 268MHz, however, when a N3DS plays O3DS games, it plays them at O3DS clock speeds. With HANs, compatible games get boast in frames and stability if they aren't badly capped (MGS3 is strictly capped at 20fps, but it won't dip lower than that). Games like Luigi's Mansion and Pokemon see better results. It also takes screen shots.
Resident Evil: Revelation never really had frame rate issues, but would stutter when enemies would spawn or when new areas load (in an elevator or giant door way). The enemy stutter is 100% gone. Enemies load in seamlessly (which actually made the game a little harder as I didn't know when enemies had spawned in) and while the stutter is still there when an area is loading in, it's significantly shorter/fewer stutters, it's nearly unnoticeable.
