Considering my first post, no. ^_~ But I am tempted to do that, just to have a more "regular" resolution.
I actually got this from taking the PSP's screen resolution, and multiplying it by 1.5. 480x272. Interestingly, the Vita would later come out, and have a resolution that exactly doubled the PSP's: 960x544. So my project's resolution now fits right in-between those two.
And I wouldn't mind having an option for fullscreen mode, if it could handle it without breaking. ;_;
