Which patch files, 50d or 50g

[Busher]

I've been playing on green beta the last week and using patch file 50g, tried to log on to blue and got the message needing the proper patch file. Previous versions of the beta patch file were usable for either blue or green, now with patch file 50g installed, do I need to put 50d back into my Titanium folder to log on to blue? The getting started guide says 50d is the latest for blue.
Thanks
