do you know if there is no way yet to add dithering + rainbow on Sonic Mania like the original Genesis games ?
This is already achievable through Guest’s NTSC preset but for RetroArch.
Thanks for the help. Nothing of what could get through CRT guest NTSC preset or NTSC adaptive from ReShade is what brings the desirable result
It’s all about setting the input resolution right, which can be a challenge sometimes.
Also not to be forgotten:
IMPORTANT -
Resolution settings ( Resolution_X and Resolution_Y ) can usually be found at the bottom in Preprocessor Definitions .
is there another shader being required in order to use preprocessor definitions ? i set number values for X and Y but nothing happens. These parameters have 320 X and 240 Y set on grey by default
(crt guest NTSC shader being used here)
This is the closest I can get.
Guest NTSC shader seem to not been fully updated to your most recent version for RetroArch.
Any chance to update it with Rainbow parameters like your wonderful current version @guest.r
Great work still. At least the dithering still can be present for modern-retro-based games ! Please dont let the rainbow been forgotten in the name of nostalgia !
First one is Guest advanced + NTSC shaders. Second one is just Advanced
Hopefully @DevilSingh or maybe @Jobima update the NTSC port to the latest. I really appreciate the work on the ReShade port, guess will be eventually updated, since the latest RA version should do for some time.
it should be updated since weeks https://github.com/Jobima1st/ReShade-Shaders/blob/Backport-update/Shaders/NTSC-Adaptive.fx (but as I said “I wait feedbacks from both users and devs”)
i tested up again, like this morning with ntsc adaptive from you and this is the best that can get.
One of the best Rainbows that have ever got recently is like the one from Guest, in his now default NTSC guest preset for RetroArch.
The version for DX9 seem like the one I used to see about 2 years ago or more
this is Guest advanced blur + NTSC adaptive, the best that could get
ynnad4, your last post in reply to me? I cant tell since this forum dont mention that if you reply under the person you reply to (or I missed how it work)
anyway, in case you dont know, guest.r did update NTSC shader after 2023-11-18-r1 (see here New CRT shader from Guest + CRT Guest Advanced updates), so the output will never be same
@Jobima oh sorry, yeah it is to you. ntsc adaptive from you and it says that is from 2 weeks ago.
The way Guest has improved Genesis rainbow is just way too good.
The current guest NTSC shader is outdated and i remember those parameters being like 2+ years ago
what I meant was, neither guest NTSC or ntsc adaptive in DX9 have the same rainbow results as Guest’s current NTSC version for RetroArch.
In ReShade, I can see guest NTSC options that are about 2 years ago. This is why asked if can be updated to current version which has a much better rainbow result + dithering
guest NTSC? https://github.com/Jobima1st/CRT-Guest-DX9/tree/Backport-update/Shaders https://github.com/Jobima1st/CRT-Guest-ReShade/tree/Backport-update/Shaders ?
@Jobima ok rechecked for the 3rd or 4th time in case i messed it up.
Yes, its your last version from 2 weeks ago.
This NTSC version has missing parameters that are available for composite Rainbow that were added up by Guest like 1 year or less ago.
This is guest advanced + guest NTSC. Cant get something closer to genesis here. The current NTSC preset version from Guest in RETROARCH is VERY accurate in contrast
I asked on this same thread many months ago if could be updated but unfortunately seem to be on the same spot.
I remember this parameters order by Guest about 2 years ago, like stated above.
This is the actual most modern way to properly allow to use Rainbow in NTSC preset for RetroArch.
Even on the screenshot you see, its how can be portrayed as it should be
NTSC Phase 2 or 3 dont give a remotely close result to what Genesis Rainbow should be.
I had this same issue earlier years ago with other presets that were offered by RetroArch developers.
Solutions to this are presets like the one being presented by Guest or Koko Aio NTSC preset. There’re others that deliver a proper Genesis rainbow. NTSC adaptive was also modified to RetroArch as far as I saw months ago. Hyllian’s NTSC preset also fixed it i think since last time checked
I think that not uptodate maybe it’s from New CRT shader from Guest + CRT Guest Advanced updates and I think it changed to “NTSC/Rainbow Effect (2-phase)” here New CRT shader from Guest + CRT Guest Advanced updates
so sorry, it’s not related to my update, maybe ask guest.r since I will not downgrade (maybe you can try older https://github.com/HelelSingh/CRT-Guest-DX9/commits/main/Shaders/CRT-Guest-NTSC.fx I think what you need is Feb 1, 2024)
thanks for your time bud
I’ve done this just recently using the Window Cast core and one of my Sega Genesis presets from my miniLED preset pack.
This is from the first time I got it working using the Window Cast Core:
I had to use the CTRL-ALT-T shortcut to switch focus back to the Game.
will have to look up on that at some point, buddy.
@Cyber orry, i was not trying to avoid your Project with different presets. Its just the fact i already have a 14 years old computer and the few times I tried with even 1080p presets I would require tons of CPU and GPU, but also slowdowns to load between each one of them.
Seem like across the months and years, your project is well feed up with different type of looks.
Always worthy, at least from here, to give a try to composite-video looking preset/shaders !
It would be a good idea to test using vulkan too or OpenGL
Thanks a lot for updating the port!
I’m getting some kind of moire effect with mshift = 1.0. No matter the preProcessor resolution, on a 1080p monitor I see moire on certain dark spots when an image moves (on Resident Evil 3 FMV, moving the camera around in Thief 1-2, System Shock 2, Serious Sam 1-2…) Is 1080p too small for a proper Shadow Mask?
Your best option for “mshift” and 1080p is to use mask 10 without any mask size changes or mask zoom.
Alternate and finer options are mask 0 or mask 5, or maybe mask 7.
