I actually looked to see if Fenrir Loader Kai supported it, but I honestly thought it was just not part of the Loader-only iso and didn't think too much about it. That'd be awesome once supported.@cafe-alpha was working on integrating a Fenrir Save Data Manager into Pseudo Saturn Kai and Fenrir Loader Kai, which would allow you to export the whole of BRAM and individual save files. However, that project was suspended once we realized that save dumping is broken in the firmware itself. I look forward to returning to that project with @cafe-alpha once Ced releases a fixed firmware. And yes, it would be cool to have Fenrir support in @slinga's tools too
I've never actually installed PSK on any of my carts since I've lacked a reason to do so (I went from a using a modchip since the 90s directly to trying an ODE) and had just assumed it was exclusive to that.
