Just tried this out. I really appreciate the hard work to move this porting forward. My initial feedback:
-I was greeted with white text on a light background on the login screen. This might be window manager-specific or no-background specific.
-Apparently spring had trouble finding a font that comes with spring upon launching that was inside 91.0/cont/fonts rather than 91.0/fonts. This does not happen with just the engine running. This folder location is representative of grabbing the 91.0 source and compiling it in place.
-Widget info was strangely set to the spring default rather than zero-k default.
-F11 did not bring up widget menu ingame. Worse, running spring by itself now seems to do the same. (now I am really confused)
Anyone have an idea on the widgets?
Edit: Found the issue with the widgets, it was similar to fonts: the source folder has a cont/LuaUI folder which wasn't being seen when launched by zero-k lobby. Moving it down one folder "fixes" that.
