Homebrew Emulator Snes9xGx new video filters

[PacBunnyXV07]

If you find the differences between the original scale2x and this scale2xEX, maybe I can derive a version in C. I have never seen a description of scale2xEX.

Couple of years ago I talk about this on the Snes9x Mushroom post and Extrem posted a link to the code for Scale2xEx.
"The relevant code is available here:

• https://github.com/extremscorner/emgba/blob/main/source/gx.c#L65-L92 (required setup)
• https://github.com/extremscorner/emgba/blob/main/source/gx_packed.c#L174-L221 + https://github.com/extremscorner/emgba/blob/main/source/gx_packed.c#L61-L106 (first pass)
• https://github.com/extremscorner/emgba/blob/main/source/gx_planar.c#L282-L413 (second pass)

You'll need to compile with https://github.com/extremscorner/libogc2 due to libogc bugs."

As I said before, It uses some TEV unit and I don't have a clue how it works. I had already found where Scale2xEx function is defined:

https://github.com/extremscorner/emgba/blob/main/source/gx_planar.c#L282

I can't understand the implementation done there. I need a pseudo algorithm code to know what's the difference between scale2xEx and scale2x. Scale2x is very simple and I know what it does.

It looks too harsh on image, IMO. Too much artifacts. I doubt someone would really use it on snes games. Maybe blargh's filters would be more suitable for snes.
