Hello,
I would just like to say prs+ is a great piece of software.
I installed it on an 'always-rebooting' PRS-505.
It works perfectly (even with error messages at installation, i forced it, and if it is asking me for startup installation after each usb-disconnect...)
I took a try at chess and won (the 1st time i won against a computer !
It's a good job, thank you.
