All the SNES versions of Final Fantasy II/IV have a bug where the long range
(or ignore row) bit is set when a charcter equips a long range weapon, but it
is not removed when switching to a weapon that is not long range.

These two patches correct this behavior in all versions of the game. Just 
make sure you use the right patch for your version. Both patches are for 
UNHEADERED ROMs.

lr_bit_fix_10_J_J2E.ips is for:
Final Fantasy II (U) (V1.0) [!]
Final Fantasy IV (J)
Final Fantasy IV (j2e translation)

lr_bit_fix_11_ET.ips is for:
Final Fantasy II (U) (V1.1)
Final Fantasy IV - Easy Type (J)

I have tested these fixes in both US versions and have not encountered any 
problems. If you do notice any instances where the fix is not working (or if 
it's screwing something else up) send me a PM at the RHDN forums:
