Hello there!
I have nullDC as my Dreamcast emulator and have been trying to run Resident Evil 2. In the US version it just takes me to a screen with the Sega and Microsoft logo and in the European version it takes me to the console main menu. I use the standard version of LaunchBox and Hyperspin so I have disc one and two on separate .rar files. I did the same for Code Veronica and it runs fine so I don't know why RS2 is giving me problems. Any wisdom you can share on the subject is greatly appreciated.
