Re: Possible to emulate 15 kHz display on 31 kHz (480p) by using scanlines?

I think it was simply not thought about that use case. The MiSTer plattforms main focus is to bring old systems to modern hardware (modern Displays, USB Input etc ) and with the I/O boards purists can even use "original" periphery (PAL/NTSC CRT TV etc.). The target audience for this specific use case is small and from that small group onl...

I zipped the modified NES and SNES cores and attached the archive to this post :)

Seems my post was moderated and the links to the cores were deleted without a notification or edit message from the mod. I suppose links to external file service are not allowed?

Re: Possible to emulate 15 kHz display on 31 kHz (480p) by using scanlines?

My settings are "forced_scandoubler=1" and i've connected my VGA monitor to my MiSTer I/O Board. You'll have to set the "scandoubler fx" to 75% in the modified cores settings. This will enable 100% Scanlines in the modified cores despite the wrong labelling. I've also made two more pictures, as the previous ones weren't that goo...

Re: Possible to emulate 15 kHz display on 31 kHz (480p) by using scanlines?

I've implemented 100% scanlines in the NES Core (i just hardcoded it into "scanlines.v" to rapidly see the results) to test it out on a Sony CPD-420GS and it's looking great. The brightness could easily be compensated within the monitors settings. NES Core 75% Scanlines IMG_20210612_191943.jpg NES Core 100% Scanlines IMG_20210612_191843.j...
