I can't answer your first question about Project Zero 4, but I can answer your config question.You can't specify a different config file for each game. HOWEVER there's a way to get your use-case to work. The way I do it is leave "Force Widescreen" and "WiiU Widescreen" turned on in my configuration file for games that support it, and when I'm building the title, force 4:3 for the games that don't. That way the forwarder is forcing "Force Widescreen" and "WiiU Widescreen" off despite what the configuration says.If you have a game that works better in widescreen using an ISO patch or a gecko code as opposed to built-in nintendont hack, check out this post where I posted about my widescreen setup , also including a custom compiled forwarder dol that forces "Force Widescreen" to be off but not "WiiU Widescreen" so that I could patch the games to be widescreen with other methods.
