I have a ta-082 and i downgraded from 2.71 to 2.6, so yea it does work. Its not hard just follow the readme. u need to copy the game folder into the game folder on ur mem stick, btw u need to make sure u run henc before u do this. Next, download mthe eboot to watever u want to downgrade to. Next, rename the eboot as UPDATE in all caps. put this into the folder in the game folder witht he rest of the stuff. Then run henc and then run the downgrader, it worked great for me
