Sega CD help needed

I've dug thru the forums and found some info to help....
But I'm still having an issue....

It's Sega CD using Fusion.

All games I have work except for Star Wars and Dune.
You press start... It goes to the CD Player.

All other games work fine....

I've tried 4 different bios file for US which are:
us_scd1_9210.bin
us_bios.bin
us_scd2_9306.bin
Mega CD BIOS V2.00 (E).bin

All have the same result... Well except for the mega one....
It just simply gives me an error stating it's a PAL/SECAM-Compatible mega cd that will no work in NTSC Regions

Anyway..... As I mentioned before it's only those two that won't work....
I've tried those 4 bios files.... I've done the ASPI thing....
Both files have been ripped and are on the hard drive.
And the controls have been properly mapped.

I'm at a loss now and don't know what to do....

Is it that these two just don't work? Or am I doing something wrong?

I'm sorry i don't have any answers for you but i was wondering if you could help me you said your games work. Are you using the actual disks or using the rom files if your using roms could you tell me how to set my emulator and Night Breed game file to work. Thanks
