XML: request sourcefile attribute

[ghost]

Hi

In the XML of MAME is an attribute "sourcefile" for example

<machine name="005" sourcefile="sega/segag80r.cpp" sampleof="005">

We can use it to see which source file is used and also know what pinball system.

In pinmame there is no attribute "sourcefile" so we can't see what code the machine is using and don't know the system.
Example:

<game name="genesifp" cloneof="genesis" romof="genesis" sampleof="pinmame">

I'm writing a small pinmame frontend to see information about the pinballs.

Would it be possible to add the attribute "sourcefile" in the XML?

Thanks
