Best Compression Methods for 'Specific' Games. Q&A

[KaktoR]

However I guess srep will most likely fail. I was asked this by some users in the last days.

I told them to find the correct srep settings / srep version or use rep before, like this
xtool:manvil:core_2.9.12+rep+xtool:dd3+LOLZ_NORMAL

Edit:

 17:25:24 - Selected ARC/DS method for Data1a-01.bin was: xtool:manvil:core_2.9.12+rep+xtool:dd3:l10,d128mb
 17:25:24 - Selected ARC/DS method for Data1b-01.bin was: xtool:dd3:l10,d128mb
