[External compressor:xtool]
header    = 0
packcmd   = xtool.exe precomp { -moption} -c32mb -t100p --dbase --dedup - - <stdin> <stdout>
unpackcmd = xtool.exe decode -t100p - - <stdin> <stdout>

-mxtool:zlib,m3:ue4,m1,k0x115E...

If you plan to add -d1 option via command line, you then have to modify the arc.ini to something like

[External compressor:xtool]
header    = 0
packcmd   = xtool.exe precomp { -option} -c32mb -t100p --dbase --dedup - - <stdin> <stdout>
unpackcmd = xtool.exe decode -t100p - - <stdin> <stdout>

-mxtool:d1:mzlib,m3:mue4,m1,k0x115E

which equates to -d1 -mzlib,m3 -mue4,m1,k0x115E
then -d1 -mzlib+ue4:m1:k0x115E when it reaches xtool
