#7373 closed feature request (outdated)
SCALERS: Old monitor rendering
|Reported by:||sev-||Owned by:||csnover|
I have some code to render natural picture. It is 3x scaler and picture it gives behaves quite realistic as an old TV.
I think that such mode would be interesting with old games like Zak and MM, as well as console ports like PCE Loom, NES MM, Sega MI1 and 3DO HE games. I.e. picture will be really close to what was back then with original.
I used code of Trevor Blackwell found at http://tlb.org/software.html (see Apple II mode for X Screensaver).
I'm still fighting with the beast and got only stetched B/W code. I'm attaching screenshot, but I'm not satisfied with the result.

I forgot to mention that realism achieved by emulation of analog DACs, so it's quite computation expensive, maybe even more than HQ3x (no, not compilation, code is not that big :) ). And due to nature of the scaler, each screen should be rendered as a whole, i.e. no partial screen updates or there would be artifacts. The reason to this is that random noise/ripples are added to the image, what results to that very realism.

These open source projects also feature some sort of "monitor emulation":
blueMSX : http://www.bluemsx.com/
VICE x64 : http://www.viceteam.org/
Might be worth taking a look at the code or contacting the authors. :)

Yup, the TV mode from Daniel Vik's BueMSX is quite terrific. It's fast, very configurable (Y/C, composite, with or without noise) and renders great even in 2x. Definitely worth a look.

BludMSX filter for ScummVM could be awesome :)

ANy news about this? Anyone contacted with the BlueTV author? Maybe he can be interested about adding it or helping on that...
