I think ill start by making a list of games that work/semi-work/dont work with psp remote joy just so its clear,and im sure we all have a lot of games to try and help him makethis better if possible.
Ill try and update it with all the umd games i have.
Mach - Works
Dragon ball z AR- works but slow
Metal Gear Solid:Portable Ops - Works with Method B
Need for Speed Most Wanted - Doesnt Work
Need For Speed Carbon:Own The City - Doesnt Work
Ridge Racer - Doesnt Work
Burnout Legends - Doesnt Work
Medal of Honor:Heroes - Doesnt Work
Tekken 5: Dark Ressurection - Doesnt Work
Star Wars Lethal Alliance - Freezes after gameboot
Wipeout - Doesnt Work
Method A:Start everything up,insert UMD and play
Method B:Start Everything up,insert umd,unplug usb,start game,start "level" then plug usb in again.
UPDATE:Im going to try my games again with Tors method,so the only game tested and updated with method B is Metal Gear Solid Portable Ops.
UPDATE 2:Ive tryed Tors method but no matter when I unplug usb my games will only go as far as loading in the xmb,then freeze after the gameboot.
P.S.Please mention your firmware that you are running,as I test mine on 3.40 OE-A.
