This is a hacked version of Star Fox Command it allows you to move with the D-pad instead of the stylus. Works properly on real hardware only, on desmume i think only v2 works as intended v3 and v4 behave same as v2 and on no$gba nothing works.

There are 7 ROMs in this pack:

-sfcu.nds – Clean ROM, un-patched moves with stylus.
-sfcu-dpad-normal-v2 – D-pad to move, removes the firing with left/right.
-sfcu-dpad-reverse-v2 – Same as v2 with inverted Y-axis controls.
-sfcu-dpad-normal-v3 – D-pad to move, remaps A to boost and B to brake.
-sfcu-dpad-reverse-v3 – Same as v3 with inverted Y-axis controls.
-sfcu-dpad-normal-v4 – Fixes v3 side effect of infinite boost.
-sfcu-dpad-reverse-v4 – Same as v4 with inverted Y-axis controls.
