@dochartaigh said in "Core Override" for Shader NOT saving + changes Video settings on its own:
• Arcade/Mame/FBNeo, to change 3-4 player settings: For "in-game system menu options" (i.e. hold Start), those should automatically save a .fs file I'll be on the lookout for. ------ ones where I have to go into (Select+X) RetroArch Menu > Options to change the 3/4-player settings I'll try the "Create game-options file" which should safe a .opt file in /opt/retropie/configs/all/retroarch/config/fbneo)
like i said, you don't need to create a game-options file in lr-fbneo if these are dipswitch settings, as it will create unique entries for every game in the global /all/retroarch-core-options.cfg, so just change the setting and it will save automatically.
