Hi HtheB

On page 44 is the 0.3.5 release. You need to download the deb and run from root. by entering: dpkg -i --force-depends psx4all_0.3.5_armel.deb

there are newer versions on this website somewhere but I had to google search to find it... and follow the above process.

hope this helps.

EDIT: run the above code in terminal with root access. the deb file needs to be in /home/user
