There is potentially additonal issue depending whether the README.namelist is trying to show variables under the correct sections or not. The two variables below belong to, I believe, the &chem section. The README.namelist file makes it looks as if they belong under &time_control section. I could be wrong. Please, let me know whether you are interested in this kind of issues.
frames_per_emissfile = 12, ! number of times in each chemistry emission file.
io_style_emiss = 1, ! style to use for the chemistry emission files.
! 0 = Do not read emissions from files.
! 1 = Cycle between two 12 hour files (set frames_per_emissfile=12)
! 2 = Dated files with length set by frames_per_emissfile
