This has to be some incredibly simple problem, but I just got NullDC and tried loading ikaruga as a .cdi file. After the Dreamcast intro, I reach a screen that says "Ikaruga" on it and has a ton of Japanese text. And it stays there--the emulator hasn't frozen, but none of my buttons do anything, either on my keyboard or through my Xpadder-enabled joypad. Am I missing something incredibly simple here? Is this just some sort of VMU startup deal or something? Any help would be appreciated.
