Also don't understand how to change location to cellar. Only Saiko's room and dungeon.

indeed,
if you are trying dungeon EX, it was not made for XSP 3.5

you have to install XSP 3 (another location again)
the modpack install procedure is the same.

Gotcha, thank you. I'll try now.

or try to edit story.txt in the pack folder.
and change
app_version = (3,0);
to
app_version = (3,5);

maybe it will work

Easyer if you install winrar to unzip then you simple rightclick the packed file and select unpack to "filename\"

Everything worked, but girls don't understand commands. Simply writing "monica, suck" and she replies "I don't know". Same with Saiko. In any location. They have some special commands there?

Also when changing location from dungeon to cellar (for example), Im appearing there alone, without girls.

never use this mod.

but I think that you have to say girl name alone, to select them. then use commands

Wondering how people doing puppet mode in this locations or how to put girl on cross in cellar. Any ideas?

puppet mode, try "relax"

I understand about puppet mode. Wondering how to turn it on in dungeon_ex mod.

That's what im getting mostly from girls. No idea how to make em move or follow commands.
