Sonic Adventure / Chankast Crash at Mystic Ruins

[S12]

Heres the problem:
I run Chankast normally, using Daemon Tools for the Virtual Drive (uploading Sonic), and everything looks good. I start playing and things are fine. This all changes when I reach a train station in the game thats supposed to take Sonic to Mystic Ruins (very early in the game). After I get on the train, the screen goes totally black and my computer tells me Chankast is "not responding". I cant seem to change this and dont know what to do, so plzzz help me out.

P.S. I think its Chankast itself and not the game because the Sonic Adventure is a CDI file (which supposedly run perfectly on Chankast)

Did you try the game on nullDC?

[S12]

null DC wont work when I try to open it
the program says, "Unable too find bios -- exiting"
"C:\Program Files\nullDC 1.0 Public Beta Setup\data\dc_boot.bin"
and then crashes

It's because you have to rename the dc_bios.bin to dc_boot.bin

well turns out after a while i got nullDC to work
and Sonic Adventure runs flawlessly (with a memory card too)
soo my prblems are solved thnx
