Thank you!! and I can see the difference between no-drop shadow and drop shadow now! 
Awesome!!
Ok! I have deleted the next preset lines:
HSM_BZL_COLOR_HUE = “357.000000”
HSM_BZL_COLOR_SATURATION = “80.000000”
HSM_BZL_COLOR_VALUE = “30.000000”
Niice!!! thanks!!
I would like to but I have a kind of steadfast rule that if I can’t successfully get the emulation working I don’t do the graphic. While the SEGA Pico is supported by PicoDrive, I haven’t had any luck getting the “Magic Pen” to work. 
If anyone else has had some luck then maybe you can help me out. 
Just a general comment, the best way to manage these presets is to save a new Simple preset, e.g. load the preset, make your changes, save - save preset (With simple presets on). I say this in contrast to taking the original preset and changing stuff in there.
This preset you saved now references the original preset from Duimon, and has your parameter changes which will override what was in his preset.
What happens now is that if Duimon needs to update the preset he can and you can get this and you get his new changes with your parameter adjustments on top.
I understand @HyperspaceMadness maybe It’s a clean way to do the same. Thank you very much.
@Duimon Let me investigate about the Magic Pen functionality with Picodrive on RA.
Good advice! The new preset will save to the root shader folder. I would suggest saving it as a core or content directory preset.
As @HyperspaceMadness says, this would get the changes for you and any updates to my presets wouldn’t break yours. (You gotta love simple presets! 
)
I tried Sega Pico with Genesis Plus GX and “MD Mouse” controller and seems to work, I’ll keep trying to see which emulator works best. 
Did you try it with an actual Pico rom that requires the Magic Mouse?
Taking a closer look at this system I think it would be a challenge to create a graphic for it. Essentially, the TV shows the game and the console has no display. (Which is no different than most other systems I have done.)
In this case I think it would be fun to do some kind of hybrid that has an integrated display, but still reflects the original system. (Complete with the front cover of the booklet that comes with each game.)
Another challenge is that the Mega Bezel shader performs scaling that the core doesn’t know about. This throws off mouse calibration. (The core still sees the screen in it’s original scale.)
Unless the core has the ability to paint a cursor on the screen and map the mouse to a joystick, (Think ScummVM or the Palm Mu core) it may not work well in the shader.
Hmmm. 
So much fun to be had.
While I couldn’t find a mouse setting in PicoDrive, I did manage to get a Pico rom to run in GX and the mouse does work!
I was able to fill the colors where I wanted. (I would have liked to be able to map a joystick to the mouse but I have a “Couch Mouse”.)
I think it’s a go on this system. I’ll put it near the top because there are a few requests in the queue.
Duimon by chance you won’t have it for MSX, Supergrafxt, Amstrad GX4000 and Famicom Disk System? They are the only systems that I lack to have reflection.
Thanks
Not yet. I haven’t actually committed to doing the FDS because it is really just an add-on for the Famicom, and I have done a graphic for that system.
If I do one it will probably be a bit like my SegaCD graphic and use the Famicom graphic as a base.
The SuperGrafx is something I want to do but it will be kind of strange to work on, a big part of what is going on with the console would be hidden by the bezel, were I to simply slap a SuperGrafx on the screen.
The MSX and the GX4000 are both graphics you will see sooner than later. (They are on my shortlist.)
The challenge with the MSX and MSX2 will be the same as the NEC PC-98. Which of the many systems to use as a source?
While you are waiting, it is fairly simple to take an existing overlay and use it as a background in the shader.
I agree with you with the FDS one, something simple like the mega CD would be enough.
Supergrafx I have never understood why the five games have different resolution, perhaps the solution would be to make a bezel for each one.
The others I am glad to know that they are on your list, by the way how many more are there on your list? 
Commodore I’m waiting for Namek to bring out his package which looks amazing.
One last thing, are you uploading all the updates to your github or do you hang it here directly?
Thanks for everything
I told you!! No rush, it was just a proposal for (I think) a beautiful-design console which I have not seen too many overlays out there.
Just in case you consider It’s interesting and fun to recreate it into graphics someday!! I’m happy that you showed interest on it!! Thank you!!!
All my graphics are 4K so they are distributed from my GitHub. I post WIP and Final version screenshots here for feedback.
Welcome to the world of the Mega Bezel shader, it doesn’t care what resolution the game is, it handles all the scaling for you. (Unlike overlays, the bezel and frame are dynamic.)
I’m still not quite sold on doing a graphic. Unlike the 32X and SegaCD (Which brought with them enhanced CPUs.) The only thing the the FDS brought was enhanced sound and save states. It’s a little like doing a graphic for the Disney Sound System, Adlib, or Turtle Beach.
Though I probably will do a graphic.(Sometimes it’s about having fun too. ) My TurboExpress, SEGA Nomad, and PSone are each just an alternative way to view the same games.
Doing these graphics brings me great joy, so of course, the pleasure is all mine my friend.
Another thing I REALLY REALLY enjoy is doing obscure systems. My goal is to create the most comprehensive set of graphics available.
So… thank you for the suggestion and, please, keep them coming!
Thanks I didn’t know, I had never used shader presets, only individual shaders.
I understand you perfectly, I could use the Famicom preset since the FDS was below, the same goes for Satellaview and Tsufami Turbo.
Maybe I’ll consider making them myself even if they don’t fit that well, are you planning to make the missing laptops? I think they are the neo geo pocket, Wonderswan and VirtualBoy, I am also very surprised that there is nothing from Atari ST and Atari 800 or XE, I understand that others like the X1, the Spectravideo or the Thomson that are less known do not have but from Atari I thought there would be.
Sorry if I ask for a lot, it’s the desire to have a perfect and beautiful Retroarch 
Patience my friend. From the second post in this thread:
I have been working on this project for only about a year.
The Neo Geo Pocket and Pocket Color are done and the WonderSwan Duo are on my shortlist.
Actually, the list of remaining systems is pretty short so they are all on my shortlist.
Just one year? Incredible, I will wait for the next updates to see what you surprise us with. 
Surprise! 
Here’s a brand new WIP.
The LowRes NX virtual console!
I may make some changes as I spend some more time filling in the details, but I think the concept is fairly complete. I may have some fun with details.
