Description

When I use it on the Wii via GBS-C, the image is distorted; it gives an error in the modified version, but thankfully the SS-Hexaeco version has a setting that corrects this, unlike your standard version. Furthermore, I would love for you to improve the implementation of the NTSC filters; they are very poorly implemented, to the point that some of them simply don't work.
In the image, the proportion is what I'm saying is wrong.
I use GBS-C scanlines; if the NTSC filters were properly implemented, it would be perfect. Two things could be done: optimize the filters or use the Genesis Plus GX filters, as they are already perfect and suitable for the Wii; it would just be a matter of adapting them for other consoles.

Research direction

No files or tests are named. Start by reproducing the distorted image on Wii with GBS-C scanlines, then compare the standard, modified, SS-Hexaeco, and Genesis Plus GX filter behavior; done means correcting the image proportions and making the NTSC filters work across the affected consoles.
