I am trying to use a .cdi CodeBreaker or Game Shark file so I can use cheats in my DC .cdi games. I am using NullDC ver. 1.0.4 with the default plugins. I downloaded the CodeBreaker & CodeBreaker Loader .cdi files from another topic in this forum. The CodeBreaker .cdi loads-up fine, but when I need to switch to the game .cdi file, it doesn't recognize the disc change. I select GDROM->Swap Disc and then select my .cdi file. It says that the lid has been opened and to insert the new disc, but it never recognizes the disc I swap. I tried using the CodeBreaker Loader, but I have no idea how to use it. If I boot-up NullDC with the loader, it just hangs on a Sega logo screen and the command prompt window says "CE: Block will be demoted to manual for the CE pass
i-cacher invalidation requested! (12 total)

How do I use a CodeBreaker or Game Shark cheat device (.cdi ver.) with the NullDC emulator? Any help would be greatly appreciated.

Thanks.
