I updated the tutorial to reflect having 2 or more functional ps3 ports or just the right ps3 port functional, this is actually important. If you have 2 or more working you can just use reactPSN on 2.61 if not you have to follow the entire tutorial. I wrote the tutorial this way because I only have the right port working.
An easier way for me anyway without using reactPSN, that BahumatLord asked me to try is using rap2rif converter, if you know how to use cygwin its much faster and easier in the long run doing this than using reactPSN (especially with just one working ps3 port). I plan on posting a tutorial for this soon as well since there isnt any for this program.
