1 year ago Duplicate of #1960. There are also a bunch of complexities for this that aren't obvious, such as the inherent limit of 256 pixels wide that would need modifications in the MMIO API to bypass.
Would it be possible to add an extended viewport functionality like in bsnes-hd or Genesis Plus GX Wide? By using the
Adjust layer placement...menu, I noticed that you could already get extra pixels in all directions (just not at the same time), so it shouldn't be too difficult to extend the resolution like that, right?
