Nostalgic film mode, anyone?

Hello there.

Ever since I moved from GH1 to EM5 I'm looking for something similar to Nostalgic film mode on Olympus.
I tried art modes, but none are as subtle as I like (although pinhole without vignette would be nice).
I have Camera raw and Optics Pro presets, which works all-right but I'm wondering if there is any in-camera trick to achieve this look.
All suggestion are greatly appreciated.

Best regards,
