Homebrew Emulator Snes9xGx new video filters

[Hyllian]

Greetings!

I thought it'd be the place to share something I was working. I've implemented two new video filters using Snes9xGx sources: 2xBR and DDT. These filters won't work in 240p, they need at least 2x the original snes resolution to work properly, so 480i or 480p are fine.

No screens for DDT. It's a kind of bilinear filter without jaggies.



And many thanks to @SaulFabre for helping me to setup the wii devkit.

A build can be found here: https://github.com/dborth/snes9xgx/actions/runs/6284311903

Hey, Didn't expect you here! I appreciate that! BTW, I intend to add other ones in the future.

I thought it'd be the place to share something I was working. I've implemented two new video filters using Snes9xGx sources: 2xBR and DDT. I just made a Pull Request to the original repository. Let's see if it'll be incorporated. If not, the sources can be seen in my fork. These filters won't work in 240p, they need at least 2x the original snes resolution to work properly, so 480i or 480p are fine.

How wonderful, congratulations bro.

Great work

I made some optimizations and got a major speed up in DDT filter (60fps in all games I tested). Fixed the DDT logic too and now it outputs a sharper picture. Other than that, added 2xBR-lv1 filter as a faster alternative to the main 2xBR.

Do you have a github?

Yes, but I made a PR to the main repo and it was accepted already: https://github.com/dborth/snes9xgx/commits/master

So maybe we are going to get a new update soon

There's a new build automatically made, so you don't have to wait for a release to try it out. You can find it here.

More speed optimizations! Now 2xBR, 2xBR-lv1 and DDT run at 60fps on most games!

Wow!
I think I'll better wait for the proper "official update".
Can't wait to try it out!

Will EPX/Scale2×/AdvMAME2× work?

It's already available as Scale2x.

This is an enhanced version of Scale2x thats used in Enhanced mGBA, its called Scale2xEx https://www.gc-forever.com/wiki/index.php?title=Enhanced_mGBA

 

[mrcroket]

Joking! It's great to have options for people that like this kind of filtering. Just not my liking.

 

[SylverReZ]

Now my games can look super blurry and smudged. Not my type of filter, imo, but good work.

Looks like it uses some kind of shader language that accesses the TEV unit on WII and GC GPU. I don't have a clue how it works, though.

Ok, thought it looks better than Scale2x because Scale2x kinda looks blotchy.

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.
