How do I make Romans playable in custom, the FAQ doesn't help...

[D.B. Cooper]

What did it mean, moving EDU files from RTW over to the EB data folder? Someone elaborate.

[MarcusAureliusAntoninus]

There is a folder called "mp custom game edu". In it you will find a file.
Go into the "Rome - Total War/EB/Data/" and find the "export_descr_units.txt". Rename it. Take the file out of the "mp custom game edu" folder and name it "export_descr_units.txt" and move it to the "Rome - Total War/EB/Data/" folder. Then play multiplayer.

If you want to play singleplayer again, exit, rename the newly placed file and change to original back to its original name.

Don't ever delete anything or save over anything.
