In your situation, just ignore the CIRC problem of your GAME - "Operation Flashpoint", I have tried to burn it last week. It is okey if you are using CD Mate or Fantom CD.
And your writer is capable of copying SD2 , just burn it.

If you still be wondering about the accurate of data, just use Fantom CD to dump it first and emulate it with Fantom CD. If everything is okey for playing game/running program, use the Fantom CD to burn it.

Fantom CD support DAO/SAO, RAW SAO, RAW SAO+SUB, RAW DAO now and the TAO support will be soon.
