Any way to specify retroarch shaders for the device?

[Tony]

I found a nice shader for gameboy and it seems retroarch allows per-emulator config settings but the same emulator Gambatte I use for both color and regular GB. How do I specify which shaders to use for each?

[RetroArcade]

Not sure if you can unless using a method like rocketlauncher does where it loads the config per whatever actual system you are using

[Tony]

Still searching but being a noob, I just learned there's a way to switch shaders using "m" or whatever you set. It didn't work for me but I may have to change my config file in some way. I'll keep searching and update when I figure it out.

Edit: Still no luck. Maybe tomorrow.

Are you wanting to use 2 different shaders for 1 game ?

[DOS76]

@Tony to cycle through shader presets you have to either save the shader which will make a copy of the preset inside the root shader folder or you can copy and paste the ones you want to use in the same location and then you can cycle through them with your keyboard or your controller if you setup the hot keys for it.

What I would do is duplicate your Gambatte_Libretro.dll (or whatever it's called) and rename the duplicate to "Gamebatte_Libretro_Color.dll" (or whatever you want) and then update your Retroarch emulator entry in LB to direct your Game Boy Color platform to that .dll instead of the normal one - now the two can have their shaders set separately. Load up a Game Boy game and set your shader. Load up a Game Boy Color game and set your shader. Done.

Normally I would just create an entirely separate "emulator" entry in LB for the purposes of dividing out certain options that I want to be able to quickly switch between (as mentioned in the post below) but so long as you have Game Boy and Game Boy Color divided into separate platforms, you wouldn't even need to do that - that method is what I use when I want to divide out the same platform for a number of different options.

I'm still working on setting this up but in the meantime, I found some Atari Lynx images, edited them and created a simple Lynx shader package for anyone interested. I couldn't find one anywhere on the internet. 

Also google drive link for visitors because I hate having to make an account to download things I come across on the internet. There's 2 versions, one for both models.

Edit: Still can't figure out how to switch between shaders on the fly, I did the above. Things would be so much faster with setting up my shaders if I didn't have to keep going into the RetroArch menu and manually choosing for each system. I'm addicted to trying out filters and after using emulators for years, it's great that we have some universal shaders to emulate bathing in the golden light of crt's, to paraphrase Bad Religion there. With Hyperspin, frontends were getting the love they deserved. With Launchbox + RetroArch, this is something else, *Hank Hill voice* I tell you hwhwat, it's taking it to another level. If I was 10 again, I never dreamed we could have such awesome setups.

Add image & fix folder structure

Also one I did for Virtualboy if anyone wants it. It's by no means accurate but makes it more fun to play than no shader. Thanks to this guy for the overlay.

I think I'm getting the hang of this. Here's another shader/overlay I did for the Turboexpress for those dozen of us who owned one and like to remember playing it in school when we shouldn't.

Here's another one I did for PSP. As you can tell, I'm not the greatest with photoshop. Sorry to keep bumping, thought I might as well share even though they're kind of amateurish.

The per core config functionality has changed to 'per core overrides'. As a result the duplicate dll trick doesn't work. Using tgbdual_c_libretro.dll and tgbdual_libretro.dll they both write their overrides to config\TGB Dual\TGB Dual.cfg. Can't figure out a workaround. Edit: Got something, sort of. Alternative suggestions welcome:

1. use the same dll core file

2. on the extra system, ie GBC for TGB Dual, add a command line switch like:

Nintendo Game Boy Color

-L "cores\tgbdual_libretro.dll" --config "config\TGB Dual\tgbdual_color.cfg"

True

3. Then disable core overrides, choose your shader and go to Configuration, Save New Config.

It still works based on the last nightly I tested which had per core overrides:

 

[dingodan]

Confused - I'm on nightlies too, and both my TGB Dual dlls write their overrides to config\TGB Dual\TGB Dual.cfg. Wonder what I'm doing differently. 

[Zombeaver]

Maybe try creating/directing to separate cfgs as well?

[dingodan]

That'll have to do until we get per core and per system - cheers. This was my initial work around - I put the details of it above in case others run into the same issue. 

[Tony]

Not sure where to put this but in case anyone wants to use this overlay, they're welcome.

Been looking for a Lynx shader - super old thread but just wanted to say thanks!
