If it converts the day of the week correctly, you are a savior of much hard work!
0 = Monday in FSX
0 = Sunday in FS2004.
I updated the software to add a -1 day offset to FS9 weekly flightplans, so it should do the job now. download here : http://lc0277.nerim.net/bglfpfsxconvert02.zip
It won't change files already in FSX format, so you may want to reconvert your FS9 files.
I did'nt really optimize memory usage. I tested it with a large PAI traffic file (65 mb), but bigger files may cause some out of memory errors.
