I mean, if you're willing to settle for a generic upscaling filter applied to JJ2's graphics output, instead of a prettier but inevitably doomed redrawing project, then sure, that's something that we'll probably look into at some point. Most of those filters are kind of terrible, and JJ2's graphics are much more complicated than Sonic 2's so I don't know how good any of them would actually look, but it's not outside the realm of possibility.

For all I know, there might be existing standalone programs that will apply an upscaling effect to another separate program? I don't want to try to google that but maybe someone else does.
