I have download the 4 CD Set of Shenmue 2 here from emuparadise. Now when i will start the game, the emulator starts normally and the bootlogo of the Dreamcast are show me animatet. After the bootlogo comes a Sega Logo and then a "Loading" text. While the "Loading" text the Demule crashes and windows close it. What is the problem.

The ISO are in MDF.

Other Games like Sonic Adventure or 18Wheeler runs perfectly (but they are in CDI format). On Youtube i seen videos about Shenmue2 where the game is run really good.. but why it don´t run on my computer?
