[gmx-users] Retinal and Schiff base parameters for ffG53a6

I would like to simulate bacteriorhodopsin embedded into a membrane. I
think ffG53a6 is a good choice - force field is quite new (at least
newer than ffgmx) and there are topologies available for the most
popular lipids, for example the set developed by Andreas Kukol.
To run a simulation I will need parameters for retinal and Schiff base
connecting Lys216 with retinal. I have those parameters for ffgmx,
however they are incompatible with ffG53a6 (and that's no surprise).
Does anyone know where I can get parameters for ffG53a6 force field
(or compatible with it)?
