Hi there guys need a bit of advice??

Purchased a DreamCast recently to play shenmue.. on playing it the

dream cast sometimes can't read the disc. Also on the rare

occasion when it does manage to load up and play a little bit of

the game the game just stops and goes back to the main screen with

the 4 options on it to update time etc.

Dunno if this is a common problem or if theres a way to solve it.

Tried cleaning the laser and elevating it but still nothing.

Cheers
