i have found out a way to load *.lua with the eboot loader v0.85.
you will have to download the lastest loader luaplayer v0.13 from this link
unzip to your psp at \psp\game.
then delete the file
go to this website and download the special eboot.pbp (it was on www.luaplayer.org but they have taken it off)
replace the eboot in the loader with this one.
now the luaplayer will work on 2.0 eboot loader 0.8.5
i have yet to get psp millionaire to work,
to get psp revolution to work, you have to rename the file the contents to
and delete the folder
it should run
here is the luaplayer off my psp that runs well
thanks Fanjita you are the man
