Well, at this point I would tell you to upgrade to 3.03 OE-C and start loading homebrew apps and games. You can also play iso's right from the XMB. Then you could pimp out your psp with custom background and icons and gameboots. Check around the forums and you will find all the info you need.
i have done it... thank you everyone that has helped.. got my ta-082 from 27.1 > 1.5 >3.02a, b >3.03a then C!! awesome.. now for games and what not... YYYYYYAAAAAAAAAAAAAAYYYYY
