alright, when you change filters you should see a noticeable difference. There may be an option in your emulator to 'allow filters' that you should check for to make sure is ticked. Your system is going to be a small factor in how well you can make this game look. Assuming you have a new-ish monitor, you are stretching a very small resolution to a 1080p or higher resolution, so there is only so much you can do to make it look less pixelated. You are usually also going from a native 5:4 ratio to a 16:9 aspect, which means further stretching. Depending on your graphics card, there may be an option (like in Nvidia control panel) to force anti-aliasing upon the program, which may make the edges look better. Also, applying a lot of filters can make the picture look even worse than no filters, giving everything a liquidy look, or very dark outlined edges on everything. I would try starting at a low resolution, and slowly raising it til it doesn't look terrible, then finding a filter or 2 to touch it up a bit. You may also consider playing in the default ratio of 5:4 with letterbox sides for a little bit of a crisper look.
If you need further help, please provide some details, such as system specs, monitor size and aspect ratio, along with the emulator you are using. Hope this helped some.
