No.

uelr+srep_new+lzma2

I think you have to work with file list to avoid errors with uelr (only include tfc, upk, ... files for uelr) if I'm not mistaken. Long time not worked with uelr to be fair. To achive that you have to open up config with _DiskSpan_GUI_CONFIG.bat file and go to the file lists. Make 2 file list files somewhere (1.txt, 2.txt). In 1.txt write all files which have lzo streams inside (mainly tfc, upk, I think). You can use wildcards (for example: *.tfc, each file type in a new line). In 2.txt write just a "*" (without ").




Save, close, start the GUI, select game folder, start.

You can also use a freearc archive with masking data compression, but I have no compatible files on hand atm. Maybe someone else can hep you otherwise.

------------------------------------------------

There are currently only 2 installer scripts comptaible, namely "Lite Installer" and "CIU beta 7". The diskspan GUI will create a "Setup.dll" file which contains all used settings to install the files.

Compression speed depends on some more things then drive speed. First of all CPU speed and input.

UltraArc make a SFX only if you check the box "Self-Extractor". Keep in mind that this way you have to done things a bit different and you have to use/edit a mask method inside Config0.ini and maybe change arc.groups file. PS: In next update UltraArc will be removed because you can do all of this things directly inside diskspan GUI (testing atm). I'm sure my friend Masquerade will tell you more on how to config mask groups and methods properly (otherwise this here will be a whole book soon and I'm not in the mood to write one).

Using xtool or any other precompressor depends on input you have. Unreal engine games which use lzo codec aren't compatible with xtool (or vise-versa) because they use some special codec (if I remember right).

If you want to avoid the split file in UltraArc, open UltraArc.ini and change

FirstVolumeSize=9999999999
CustomVolumeSize=9999999999

or something even bigger, don't matter.

If you want max compression use lolz instead of lzma2.
