Override scaling mode using keypresses on startup #147

Open patters-match opened 8 months ago

patters-match commented 8 months ago

Sometimes I like to play a game hardware scaled, but sometimes not. Editing a text file on-device to change this behaviour is a bit tricky. Would it be possible for open_agb_firm to copy the behaviour of the Virtual Console emulators which will display unscaled if Start or Select are pressed during startup?

It's not really mentioned in the README but per game configs can override all settings from the global, default config if that helps. Otherwise i think it makes more sense to handle this via a GUI eventually.

I do think the Start/Select pattern would be ideal to force unscaled, since that's the established pattern (even for Twilight Menu++) and it's probably a lot easier to implement than a full GUI will be. Whether or not to use a different key combo to force bilinear Vs hardware is kind of a secondary concern. I'd judge it's possibly less likely a person would want to alter that, as people tend to be fans of one mode over the other.
