Hello i cannot finish my game in tomb raider the legend in my psp.. im stop at the dragon outside the king arthurs tomb what will i do?

Are you using an official firmware or custom firmware?umd or memory stick?normally,if you're using official firmware and umd and given your issue,there might be something amiss with the psp console.if you're using on the other hand a custom firmware and memory stick,make sure that the configuration under the recovery menu (turn on psp while clicking the R button) is set to memory stick.or still,try playing the game on another psp console and see if you will encounter the same problem.if yes,try reinstalling the game on the memory stick,it might have been corrupted,and see if it will work.use caution,no guarantees.hope this helps.
