Yeah one thing I would like to get at some point is expose some arbitrary values from retroarch, like float values for led0, led1, led2 in the shading system, then we could drive some basic stuff in the shader.
@oneshout you are loading a layout in the mame core to get what we see here correct? So the layout stuff we see 8s drawn in the core image?
Here’s a new WIP…
The Palm m515 (Mu Core).
This is pretty hard to get running but the author has a discord and it is in active development so… fingers crossed. 
I have curated a TON of games for it so I will be watching closely.
Small OCD pass on the Palm. 
I worked on the LED a bit and changed the background. (Of course this can be replaced by the user in the new shader version.)
So… I didn’t like how the graffiti area stayed lit when the lights went out, so I created my own and used new shader magic to place & mask it.
I kept it enabled in the core (It can be disabled.) so the bezel would remain the same size.
Now it reacts to ambient light as it should.
BTW. Just to share a little about what my plans are. I am going to be working on some obscure systems…
and some not so obscure…
And then some handhelds…
I have decided that there are a few cores I will not do graphics for.
I think for these, (With the possible exception of PICO-8) that my DOSBox graphic will be appropriate, or any of the TV graphics.
I may reconsider this decision after I am finished with the rest of the cores.
Again, in deference to @TheNamec and his awesome, soon to be released Commodore package, they are at the very end of my list. (If I do them at all. )
I’ll need your C64 series C, C128, A1000, A2000 and A4000 macro details photographs sooner or later my friend can’t wait for next RetroArch to be out
Did you make any kind of geneic arcade cabinet?
If you scroll up you’ll see that I did a Naomi. You’ll also see that it’s color will be customize-able.
I have not yet done a generic arcade. I do have plans to do one sometime in the future. 
When I do, it will also have the custom color parameter.
Neither can I. I suppose I should get to work on converting my presets so they will be ready, if @HyperspaceMadness thinks the parameter names are pretty final.
That, combined with the roadmap I posted, should keep me busy for a while. 
OK… I think this is final.
I added some drop shadows to the buttons to give them dimension, (They were looking very flat. 
) and made some magic happen with the reflection.
If you look at the night version above you will see that the graffiti area reflects on the bezel, which wouldn’t happen, so I used the Gel layer to cover it with black at the crt level. All is better now.
I mentioned that this is hard to get running. Specifically, the coordinate system places the screen buttons relative to the veiwport so you have to click with your invisible mouse cursor on the screen where you guess the button would be if you were using the core at full screen. (NOT very elegant.)
The solution is to turn on “Left joystick as mouse” in the core options. This gives you an on-screen cursor that you can click with. The cool thing is, since I am covering the graffiti area with my own graphic, I can hide the cursor under it while playing a game. (VERY nice! 
)
There are a lot of well done games for the Palm!
Hey guys, just an FYI.
I don’t know about the stock version, but @hunterk’s Dolphin core build supports the new RVZ compression. I used the standalone emultator to convert from GCZ and saved 122GB on 300 games! 
@Duimon oh, it’s an excellent new, you guys are really amazing (tks a lot to @HyperspaceMadness for the hard work on shaders)
@TheNamec The idea come from Ms. Pacman (Animated) - MAME 0.227… just a modif of the pacman.cpp (Driver source), a mame recompiled (i’ve done a mame rebuild and a retroarch mame core to for the test) with the last version and the good animated overlay
If you want to test and don’t have time to recompile (take a long…long time, near a night for me for just 1 rebuild ), i share my rebuild here (mame64 + retroarch core 0.227 : Mame rebuild
The link for the animated overlay from the video : Ms Pacman Overlay
For the P-UAE, i prefer using FS-UAE (with Launchbox) to manage all my ADF roms, WHDload, CD32 and all my compils i’m using an overlay with all leds activated to. Of course, no shaders but this emulator is incredible
I know they were a WIP FS-UAE core for retroarch but he is based on the 2.8.1u5 version ( 4 years old), too old for me
@HyperspaceMadness yep, i’m loading a mame bezel in the mame core i love testing stuff that i usualy not to use
PS : Maybe it can help to test the new shaders incoming with this kind of bezel
@TheNamec FS-UAE overlay i’m using with full Leds + floppy sound but be sure i will test the new P-UAE core :
I’m. In. Love. 
we need this on libretro PUAE!
PS: am I the only one hearing Chris Huelsbeck intro theme in my mind as soon as this image popped out in the thread!? 
a bit off topic but …Chris Huelsbeck, one of the best composer for C64 and Amiga
Here’s a new WIP…
Fairchild Channel F!
Although I am happy with the result, I wish there was more that wasn’t hidden by the bezel. This is one of those times I felt I needed to modify the default bezel settings. Thanks @HyperspaceMadness that it is so easy to do.
A vintage monitor would work really well here.
I did a really quick OCD pass.
I did some work on the game cartridge, and actually dimmed the screen a bit using grade parameters. (This system is REALLY bright.)
Here’s another new WIP.
Elektronika BK-0010!
These simpler systems all seem to beg for some brightness reduction. (They hurt your eyes.)
Here’s a real work in progress! (And a first for this project.)
I’ve been having so much fun with the PICO-8 (retro8 core) that I thought I’d see what kind of imaginary handheld I could create for it. (The screen resolution is so low I thought this would be the perfect way to play these games.)
Lots of details still missing but I like it enough to commit to the idea.
