[nibbles27`]

Hey im working with the nesterj 1.11 source trying to add a resolution that renders the pixels properly just like full screen setting but shrunk to 4:3. The source actully looks quite easy to manipulate i just need to change about 5 lines ive worked with NesDS (this looks like cake compared to it) if i could just get a bit of help would be nice ive got the right idea a bit of proof reading would help here is the lines i have changed
