I cant get the -home flag to work. I want to store every thing in the pico8 directory so i can make it dynamic and portable. But pico8.exe - home .\ dose nothing. Neither dose hardcoding the path like pico8.exe - home c:\pico-8\

With quotes or without, does not seem to make a difference.

Your BBS message has a space between the hyphen and the word "home". If that's the way it's typed on the command line, that won't work.

I confirmed that this works on Mac OS:

./PICO-8/PICO-8.app/Contents/MacOS/pico8 -home ~/Desktop/picotemp

The space was an accident. There is no space when I was trying it for real. I'm on windows, so I'm wondering if that's the problem.
