Does IRQ-loaders work on emulator?

Hi, I try to figure out how to get an IRQ-loader to work on my ccs64 emulator. I tried several loaders, even the one on this database from Agony, but everytime I try it the system crashes. Is it not supported by the emulator or must I set the drive emulation in a certain way?
I don't have a real c64 to test it at the moment :( so I'm kinda stuck here.

Yep, IRQ-loaders works.

In Vice be sure to check "True Drive Emulation".
In CCS64 i guess you should set 1541 Emulation to "on"

Also, if CCS64 fails, try VICE. It's got somewhat better emulation of most C64 features.

Even with CCS64, I've never had any problems... The latests betas are almost as good as VICE (and for NTSC emulation, even better) I wonder what you could be doing wrong to NOT have IRQ loaders working...

Thanks for the hint, Johan, I just have added a routine to check for more than one active device on the bus to my 2bit+atn loader's init routine. So now the init routine will return an error with more than 1 turned-on device on the bus. That won't help for the systems where already more than one device _connected_ to the bus will screw the protocol, though, but it will help most users who have no idea of the 2bit+atn protocol's big disadvantage. (So now please add error screens to your demos) :D

Thanks for the replies.
I got it working though, it was a device setting in the emulator after all.
It works realy smooth now
