Definitely not since like I said on other posts I put a clean atmosphere 1.6.2 with latest Hekate and all the
@impeeza latest Hekate Sigpatches files with even his hekate_ipl config and 0 content added to atmosphere and still could only play games upto my FW 16.1.0 and every game requiring FW 17+ gives a error, same exact thing with just sys-patch added with everything ON (with off course everything needed to use it like salty, Tesla, Ovlloader...).
It can only be Hekate own boot method that breaks the feature of running games at a much lower FW that is present officially on atmosphere when using fusee payload since I always have done it for years and would only require updating Hekate+atmosphere+Sigpatches to play games requiring a much higher FW, Hekate fss0 simply seems to break it.
You can try your self making a new emunand on other mSD that you might have, update it to FW16.1.0, use Hekate with FSS0 and latest Hekate sigpatches and try a fw17+ required game to see If it works for you (mudrunner for example gives error, Kingdom come deliverance works fine as it needs a FW below 16.1.0 but after updating it gives error as the update also requires FW17+).
At least using fusee I guarantee 100% any latest game will run fine on FW16.1 and hell like I said previously even on FW 15.0.0 I could play some FW17 games fine but really had to update to 16.1 because of one that wasn't working which still requires fw17+ but everything runs fine on 16.1 so far...
