Greedy bastards. SBPro2.0 was 40$ on ebay in 2016, when I was collecting. I have 2. DOSBox still doesn't produce accurate lowpass filter to emulate the SBPro2.0.

Dosbox PC speaker emulation is still broken in 2020. Any reason this patch which is accurate to real hardware is not part of the official dosbox yet?

Nuked OPL is accurate to the real hardware, and there are indeed cases where inaccuracies are clearly audible. Some examples: from nukeykt himself: DOSBOX fork with better FM synthesis?

@dosbox team What is the reason Nuked OPL is not part of dosbox yet? Many emulators and professional software adopted it.

Yes, thank you that worked. And thanks to Yesterplay80 for maintaining the ECE edition for years.

I think SVN 4352 broke OPL completely. No music in Doom, with Nuked-OPL. It also broke the stereo compatibility of OPL3, even with the Default OPL option. https://sourceforge.net/p/dosbox/code-0/4352/

The filter will apply to whatever resolution you set in fullresolution= or windowresolution=,, what you do with it afterwards is not dosbox's concern. How are you scaling back down to 320x40?

Yes, it is glorious. The higher you native resolution of your display, the sharper the image will look. When the upscaling factor is big (say from 320x200 to 1080p) the sharper the image will look with less and less blur, and accurate pixel geometry. There is no modern emulator with low resolution …

He's talking about "sharp bilinear": https://github.com/rsn8887/Sharp-Bilinear-Shaders Yep. This is exactly what a "big integer prescale then interpolation" does, and exactly what I am asking for. "sharp-bilinear-simple" This shader does an automatic optimum integer prescale (2x, 3x, 4x etc.), …

320x200 or 320x240 scales perfectly to 1600x1200 so no interpolation is used,, forcing 2x or 3x is no longer integer of 1600x1200 and it interpolates the image. I'm not sure dosbox is doing that, but rather my gpu,, need confirmation. The point of all my commotion is to make the pixels sharper yet …

I see there is some new magic going on with the official scaler. Using scaler=none and opengl, at certain resolution bilinear filtering is applied but on others not. Easiest to test with Quake that can switch all resolutions on the fly. 320x200, 320x240, 800x600 there is no bilinear filtering,, but …
