I believe you guys of course, I just have no idea how it works. Take a game like Ico, which ran at sub SD resolution. There's no option in the game to alter that. I don't doubt if you could hack the game you could alter the native resolution, but I don't understand how the emulator would be able to do that.
Because a game's output rendering, from what I'm aware, isn't largely controlled by the game itself, but the hardware, firmware, and OS of the system it's running on.
It's why you can't just play console games on a PC off the bat. There needs to be some kind of software that
renders the game files, hence the existence of emulators.
Because the software is emulating it its own way on different hardware, it has complete control over the way the game is rendered. An emulator built to render at a higher resolution can in turn render a game, art assets and all, at a higher resolution.
Doesn't mean it will run well or there wont be graphics issues.
