DOSBox with Mala

[Narcissus04]

Ok so I've searched and searched but can't find this.

I'm assuming people have been able to set games on Mala using DOSBox. I've been attempting to with .bat files.

I'm targeting Mala at DOSBox and have set up under autoexec so it automatically mounts C:\ to the same place where I have the .bat files stored.

The Bat file reads as such:
cd Metal
ML.bat

Malas execution reads : %rom%.%ext% although I have tried other variations

I'm probably missing something pretty obvious here but if anyone would tell me what it is I'd be pretty grateful.

While I'm on the subject of crying out for help has anyone had luck getting WinUAE to work?
