Thanks

Also, recommend you choose a filter that only interpolates the horizontal since 5x crop will be a vertical integer.

Thanks for the tip

For example, if you’re running a 256x240 core on 1080p, you could set 1280:1080 for a five times horizontal integer upscale (and a pixel aspect ratio of 5:4.5).

This just now clicked with me, this should work, I'll try this.

Hi everybody! I tried kernels with 5x scaling - great at 1080p! Make sure to drag it to the main branch! I'm having some problems with the NES core - it doesn't scale correctly in PAL / Dendy mode. Works normally only in NTSC .. Can I fix it somehow?

Not an easy fix because PAL actually has more vertical resolution. Although not impossible to make a core that does the same cropping in PAL and hope that no game takes advantage of the extra PAL resolution.

C64 could really do with some X5 love.

Sorg released a test build of 5x cropping for NES core and its working fantastically. Most importantly custom aspect ratios work with his test build!!!

Here is NES running in glorious 5x by 6x integer scale via custom aspect ratio setting (64:45). Thank You Sorg for considering this feature.

I just tested it out and I'd like to report a bug, I can't see all of the pixels that I should be able to see!

When I created this thread, I had one goal, to try and make a convincing case for 5x crop.

Well today 5x crop option has become an official feature on NES, SNES Genesis, SMS, Mega CD, Neo-Geo and TG-16 cores. Not only that but there is a feature called "crop offset" that allows you to move the image up or down a few notches to gain back any critical information a direct centered crop might lose. Thanks to everyone who gave their thoughts on my thread and most importantly thanks to Grabulosaure and Sorgelig for making it happen.

Now time to have some fun.

all the cores have that 5x crop and offset options greyed out even though I'm running video_mode=8 (1080p) ?

Option is enabled when all these conditions are met:

• Resolution needs to be 1920x1080
• vscale_border isn't used (or vscale_border=0)
• vscale_mode isn't used (or vscale_mode=0)
• forced_scandoubler=0
• in OSD menu Scandoubler Fx:None

got it thank you, Im an idiot

You probably are using something other than vscale_mode=0

I've just tried it with the Megadrive core and it looks fantastic. Only a bit of the overscan area is cropped, the resulting full-screen image has perfectly clear scanlines, really nice.

The new 5x crop option is excellent. Thanks to all who advocated for it, and a special thanks to those who implemented it. Can someone please specify the custom aspect ratios that are needed to get full integer scaling with a 6:5 pixel aspect ratio on NES, Genesis, and SNES? I see 64:45 posted above - is that value correct (I've seen 64:49 posted other places), and does it apply to SNES and Genesis also? Thanks.

Bob at retrorgb gave his take on this, and brought up the idea of shifting the image up or down.

64:45 for 6:5.

This was implemented. The setting is "Crop Offset".

I recently posted a build of the Genesis core with a menu option for automatic integer horizontal scaling. See this post. I made it with the current Genesis code from GitHub, so although I haven’t tested it it should work with the 5x crop mode. I’d be interested to hear feedback on if it’s working for people.

I’m kind of confused to see that SMS has a 5x crop option. Again I haven’t tested the latest version, but the SMS’s vertical resolution is 192 so it already fits five times multiplied at 1080p. Is it just for border mode?

Just tried this with 5x vertical crop on and both AR settings in "Original": this is AMAZING! I've got no shimmering on both Narrow and Wide options you gave. No more pursuing the right custom AR settings manually, I believe! I really think Sorgelig should consider adding this to the package, as this will come in super handy for games changing horizontal resolution! Great job!

I just updated and tested the 5x crop in NES, Genesis, and SNES so far, and it look great, and scrolls much smoother. It also makes things easier to see on the sofa furthest from the TV (about 18' away.) I also saw that there is an offset option which I'm sure will come in handy for some edge case games, but what isn't clear is if the offset setting is per-game or applies core-wide ? The former would seem to make the most sense since most games don't seem to need any offset adjustment from what I've seen thus far, and those that do might need it in different amounts and/or direction.
