Based on the fe8 remove arrow wiggling advancing RN patch ([FE8] Remove Arrow Wiggling Advancing RN), I was able to create a version of this for FE6, FE7, FE7J, and FE8J using the febuilder disassembler and some guessing and checking. You could put these in a txt file and load it using ‘Insert EA’ in febuilder. Here they are:
FE6:
PUSH
// Remove arrow wiggling advancing RN
ORG 0x19730
SHORT 0x2000 0
POP
FE7:
PUSH
// Remove arrow wiggling advancing RN
ORG 0x19F90
SHORT 0x2000 0
POP
FE7J:
PUSH
// Remove arrow wiggling advancing RN
ORG 0x1A370
SHORT 0x2000 0
POP
FE8J:
PUSH
// Remove arrow wiggling advancing RN
ORG 0x1A44E
SHORT 0x2000 0
POP
Thanks for the patch implementation for FE7J, FE7U, FE6.
// patch already exists for FE8J.
I added it as a patch for FEBuilderGBA.
//for example.
//for FE7U
