There's a new linker called ULINK available for BCB that is much (much) faster and reliable than the BCB one. (It can be downloaded from ftp.styx.cabel.net)
However, I don't think its MAP files are Eurekal Log compatible. A sample ULINK map can be had from : http://www.profotosoftware.com/PFSPreviewWk.map
This is using its 'detailed' setting. Is it detailed enough or do they need to enhance it?
