One of the few programs that keep me from leaving windows behind completely is Romcenter. Romcenter rocks! I am certain i am not the only full time linux user that 'wished' Romcenter was avalible on our platform. If the developers of Romcenter do not want the extra work, one of the KDE developers or Gnome developers would love to port Romcenter to linux.
Another possible solution is running Romcenter in Wine. I have done this, it installs fine, runs fine, but will not open the DAT file. Maybe making a version of Romcenter compiled with winelib would do the job! Anyone ever get Romcenter working in wine?
If anyone else would like to see Romcenter running natively on Linux, post below and show your support!
