Emulator Problem: emulator detects my Game CD as a music cd

I have problem abount Dreamcast Emulator

I use DAEMOON Tool Lite 4.30.1 Mount Image file of Resident Evil : Code Veronica (.nrg)

I run Chankast 0.25
Configure Drive ==> i: ( My Virtual CD Drive)
Option ==> Capcom Hack
Run

but I cannot play game the emulator detects my image file (.nrg) as a music cd

I change to use nulldc to Play game but result same as Chankast


Fig 1 from Chankast 0.25





fig 2 from nulldc

Have you set the correct region for the system (If its a US version of the game afaik you need to set the console as US).

Thank you.

the Answer is my image file(.nrg) corrupt.

when I down load new image file(.cdi) from new Source.

the Emulator can play Game.
