For me if I use --diff=* in arc.ini it doesn't work, return:
ERROR: write error (disk full?) in compression algorithm xtool:c256mb:mbk2

Arc.ini

--cache=0
[External compressor:xtool]
header    = 0
default   = -c64mb -t100p
packcmd   = "{compressor}.exe" precomp { -option} --diff=* - - <stdin> <stdout>
unpackcmd = "{compressor}.exe" decode -t100p - - <stdin> <stdout>

pack.bat
arc.exe a -ep1 -dses --dirs -s; -lc- -di -i2 -r -w.\temp -m"xtool:c256mb:mbk2" data.arc "pack\*"

I also tested using it directly from the command line after removing --diff=* from arc.ini:
xtool:c256mb:mbk2:-diff=*
xtool:c256mb:mbk2:df*

Arc.ini

--cache=0
[External compressor:xtool]
header    = 0
default   = -c64mb -t100p
packcmd   = "{compressor}.exe" precomp { -option} - - <stdin> <stdout>
unpackcmd = "{compressor}.exe" decode -t100p - - <stdin> <stdout>

pack.bat
arc.exe a -ep1 -dses --dirs -s; -lc- -di -i2 -r -w.\temp -m"xtool:c256mb:mbk2:df*" data.arc "pack\*"
or
arc.exe a -ep1 -dses --dirs -s; -lc- -di -i2 -r -w.\temp -m"xtool:c256mb:mbk2:-diff=*" data.arc "pack\*"

If I don't use --diff=* it compresses normally.

Am I doing something wrong?

The --diff parameter in XTool sets a max size in bytes or percentage size of the stream in order for XTool to accept the stream.

The * character is just a placeholder (a wildcard effectively meaning anything/everything). My explanation meant you'd need to change this to an integer.

By default, XTool will not accept a stream if the generated XDelta patch is greater in size than 5% of the stream, but using --diff= allows you to increase this threshold.

You can use --diff=20p to set the max patch size to be less than or equal to 20% of the stream size for XTool to accept the stream. You can also use an integer to specify a max patch size in bytes (e.g. --diff=50000).
