Hi Lyndel, nice to hear from you!

PCF is not supported, since it uses an encrypted form of the Pronto Hex codes. (Opening in PEP and exporting in another format might decrypt it though...)

For the XCF: while my work is based on reverse engineering, it is quite possible that either there are different versions of the XML format, or that I have missed something. I will be happy to have a look at any XDF file that is not accepted. Please send/upload it, for example with personal PM. (Actually, ConfigEdit.xml will be sufficient if size is a problem.)
